President Donald Trump has extended the Iran conflict ceasefire by an unspecified duration, linking the extension to Tehran's submission of a proposal and the conclusion of negotiations. However, the US maintains a naval blockade, which Iran deems a violation of the truce. Meanwhile, regional violence persists, Lebanon faces a $587m humanitarian crisis, and oil flows through the Strait of Hormuz remain critically restricted. Key Developments Conditional Ceasefire Extension: Trump stated the US would maintain the ceasefire until Tehran submits its latest proposal and negotiations conclude, keeping diplomacy open while simultaneously applying pressure. Naval Blockade Remains: Despite the truce, the US naval blockade of Iranian ports continues. Iran’s Foreign Minister Abbas Araghchi described this as an "act of war" and a violation of the ceasefire agreement. Regional Violence: Violence has not ceased in the broader region. Israeli settlers killed two people, including a child, in the occupied West Bank, and Israeli strikes in southern Lebanon have wounded civilians despite a 10-day ceasefire. IRGC Threats: The Islamic Revolutionary Guard Corps (IRGC) warned that oil production across the Middle East could be targeted if attacks were launched from Gulf neighbours' territory. Humanitarian Crisis in Lebanon: Lebanese Prime Minister Nawaf Salam announced that Lebanon requires $587m to address the ongoing humanitarian fallout from the conflict. Data & Market Impact Oil Flow Restrictions: Shipping through the Strait of Hormuz remains severely limited, raising immediate concerns over global oil supply chains and potential price volatility. Humanitarian Funding Gap: Lebanon’s request for $587m highlights the economic devastation in the region, a figure that underscores the scale of infrastructure and social damage beyond military targets. Economic Support Mechanisms: Reports indicate the US is considering a currency swap with the United Arab Emirates to support the Gulf ally’s economy amid war-related strain, signaling a shift in regional financial strategy. Why This Matters This standoff represents a critical juncture in Middle Eastern geopolitics. The extension of the ceasefire without a clear end date creates a precarious atmosphere where diplomatic engagement is possible but highly conditional. For the global economy, the continued restriction of the Strait of Hormuz is a major risk factor; even a minor miscalculation could trigger a supply shock that drives oil prices higher, affecting inflation worldwide. For the people on the ground, particularly in Lebanon, the ceasefire has not translated into stability. The $587m humanitarian appeal reveals a deepening crisis that requires immediate international attention, separate from the high-level diplomatic chess being played in Washington and Tehran. Expert Insight The core of the current stalemate lies in the fundamental disagreement over the definition of a truce. The US views the blockade as a necessary pressure tactic to force Iran to the negotiating table, while Iran views it as an act of aggression that negates any diplomatic goodwill. This disconnect suggests that the current ceasefire is fragile; it relies on the restraint of both parties rather than a mutual agreement on terms. Furthermore, the strategic messaging from both sides is polarized. While President Trump oscillates between conciliatory and hardline rhetoric, Iranian officials are doubling down on their refusal to negotiate under "the shadow of threats." This indicates that Iran is preparing for a long-term containment strategy rather than a quick resolution, potentially forcing the US to choose between a prolonged economic squeeze and a return to military escalation. What Happens Next The coming days will be decisive. If Tehran does not submit a proposal by the extended deadline, the US may be forced to choose between lifting the blockade to save the ceasefire or maintaining it and risking a breakdown in talks. Additionally, the planned ambassador-level negotiations in Washington between Israel and Lebanon will be a litmus test for the broader regional de-escalation efforts. Failure in these talks could reignite hostilities in the south, further destabilizing the already fragile Gulf security architecture.

The Race Against a Vanishing Ceasefire Window As JD Vance prepares to fly to Islamabad, Pakistan is scrambling to persuade Iran to sit down with the United States before the cease‑fire expires on Wednesday evening Washington time (early Thursday in the Middle East). Pakistani officials remain cautiously hopeful, but a series of US actions over the past 48 hours have injected fresh scepticism into the mediation effort. Escalation on the Ground: US Deployments and Naval Seizures In the last three days, at least nine US aircraft have landed in Pakistan carrying personnel and equipment for the Vance‑led team. The US delegation, including Special Envoy Steve Witkoff and Jared Kushner, previously led the first round of talks on April 11. Simultaneously, US naval forces have intensified pressure at sea, boarding the Iranian‑flagged cargo ship Touska in the Gulf of Oman and a second vessel, M/T Tifani, in the Asia‑Pacific. Tehran denounced the actions as “extremely dangerous” and a breach of the cease‑fire. Numbers Shaping the Standoff Eight weeks into the US‑Iran war. Two‑week cease‑fire set to end Wednesday evening (US) / early Thursday (Middle East). Nine US aircraft deployed to Pakistan. Two Iranian‑linked ships seized by US forces. Iran’s parliamentary speaker Mohammad Bagher Ghalibaf publicly rejected negotiations under threat. Regional Ripple Effects: From Islamabad to the Strait of Hormuz The blockade of the Strait of Hormuz remains the central bargaining chip. Analysts note that Iran’s willingness to soften its stance may hinge on a tangible easing of the naval blockade, while the US seeks to remove the “Hormuz card” entirely. The internal split between the Islamic Revolutionary Guard Corps (IRGC) and Tehran’s diplomatic corps adds another layer of complexity, with the IRGC pushing for a hard‑line stance and threatening attacks on passing tankers. Pakistan’s unique position – maintaining security ties with both Washington and Tehran – makes its framing of the negotiations critical. A successful mediation could preserve regional stability; a collapse risks a rapid return to full‑scale conflict. What Lies Ahead: Scenarios for the Next Round of Talks If Iran sends a delegation, a second round is slated to begin on Wednesday. Possible outcomes include: Breakthrough: A limited agreement on the blockade and a temporary pause on uranium enrichment, allowing limited Iranian oil shipments. Stalemate: Iran refuses to attend, the truce expires, and hostilities resume, potentially escalating across the Gulf region. Partial Deal: Both sides agree to extend the cease‑fire while continuing back‑channel talks, keeping the door open for a comprehensive settlement. Analysts warn that failure to secure a deal could lead to “devastating destruction,” as the war has already demonstrated a high willingness on both sides to employ military force to achieve strategic objectives.

The Escalating US-Iran Standoff United States President Donald Trump has claimed a second round of negotiations with Iran will take place in Pakistan on Tuesday as mediators try to revive negotiations before the end of an ongoing yet fragile two-week ceasefire. The announcement on Sunday came alongside a sharp escalation in rhetoric. Trump warned that Iran must agree to a deal "one way or another – the nice way or the hard way" and threatened to target key infrastructure if negotiations fail. He also renewed his threat of striking "bridges and power plants", which experts said could amount to war crimes under international law. Iran, however, has so far denied it will participate in the talks, accusing the US of "armed piracy" after US forces struck and seized an Iran-linked tanker on Sunday, further heightening tensions between the longtime adversaries. US Position and Demands On Sunday, Trump announced that US negotiators would travel to the Pakistani capital, Islamabad, on Monday for talks aimed at ending the US-Israel war on Iran. In a social media post, the president did not say which officials would be sent to the talks. Last weekend's first round of talks, at which Vice President JD Vance led the US delegation, ended without a deal. Trump accused Iran of violating their two-week ceasefire, which is due to expire on Wednesday, by opening fire on Saturday in the Strait of Hormuz. The US president threatened to destroy civilian infrastructure in Iran if it doesn't accept the terms of the deal being offered by the US. "We're offering a very fair and reasonable deal, and I hope they take it because, if they don't, the United States is going to knock out every single power plant, and every single bridge, in Iran," Trump wrote on his Truth Social platform. In a further escalation, Trump said an Iranian-flagged ship called the Touska was "stopped" by US forces in the Gulf of Oman "by blowing a hole in the engine room". He said it was trying to get past the US naval blockade of Iranian ports. US forces boarded the ship and took physical control of the vessel. Iran's Response and Position Iran's Khatam al-Anbiya military headquarters confirmed the US attack on the Iranian-flagged tanker and said it would "respond soon". Then, Iran's Tasnim News Agency reported that Iranian forces had sent drones in the direction of US military ships. Ebrahim Azizi, the head of the Iranian parliament's National Security Committee, told Al Jazeera that Iran's actions during talks with the US are strictly guided by national interests and security. When asked if Tehran intends to participate in the talks in Islamabad, he said, "Iran acts based on national interests." "We see the current negotiations as a continuation of the battlefield, and we see nothing other than the battlefield in this," he said. "If it yields achievements that sustain those of the battlefield, then the negotiation arena is also an opportunity for us … but not if the Americans intend to turn this into a field of excessive demands based on their bullying approach." Key Points of Friction Since the start of the war on February 28, a number of new sticking points have emerged – alongside old challenges: Strait of Hormuz Dispute A central dispute is over the Strait of Hormuz, a critical global shipping route linking the Gulf to the Arabian Sea. One-fifth of the world's oil and liquefied natural gas (LNG) supplies were shipped through the strait before the war began. Iran insists on sovereignty over the waterway, which lies within the territorial waters of Iran and Oman and does not fall into international waters, and stated that only "nonhostile" ships could pass. It has also floated the idea of levying tolls while Washington demands full freedom of navigation. After the war began, Iran in effect closed the strait by forbidding transits, attacking ships and reportedly laying sea mines. Shipping traffic has since dropped by 95 percent. A week ago, the US implemented a blockade of its own. Its Navy has been blocking Iranian ports to pressure Tehran to reopen the vital waterway, adding another obstacle to the talks. According to Rob Geist Pinfold, a lecturer in international security at King's College London, Trump's stance on the strait has shifted during the conflict and remains unclear. "We've had Trump say that he would be open to jointly controlling the Strait of Hormuz with Iran, where both sides collect a toll for shipping," Geist Pinfold noted, calling this "completely different to the demands of the US on paper but also the demands of the US's regional allies like the Gulf states and Israel, … who would regard any deal that entrenches Iranian control of the Strait of Hormuz … as a stab in the back". "This isn't just between the US and Iran. It's about the US having to keep its regional allies on side," Geist Pinfold told Al Jazeera. Nuclear Enrichment Standoff Another core issue is Iran's nuclear programme, particularly its stock of enriched uranium. The US and Israel are pushing for zero uranium enrichment and have accused Iran of working towards building a nuclear weapon while providing no evidence for their claims. Iran has insisted its enrichment effort is for civilian purposes only. It is a signatory to the 1970 Treaty on the Non-Proliferation of Nuclear Weapons (NPT). In 2015, the US was a signatory to the Joint Comprehensive Plan of Action (JCPOA) under then-US President Barack Obama. In that agreement, Iran pledged to limit its uranium enrichment to 3.67 per cent, which is substantially below weapons grade, and to comply with inspections by the International Atomic Energy Agency (IAEA) to insure it wasn't developing nuclear weapons. In return, international sanctions on Iran were lifted. However, in 2018, during his first term, Trump withdrew the US from the JCPOA despite the IAEA saying Iran had complied with the agreement up to that point. In March 2025, Tulsi Gabbard, the US director of national intelligence, testified to Congress that the US "continues to assess that Iran is not building a nuclear weapon". A month later, the IAEA estimated that Iran had 440kg (970lb) of 60-percent enriched uranium. While that is also below weapons grade, it is a short jump to achieve the 90-percent purity needed for atomic weapons production. On Sunday, in strongly worded comments, Iranian President Masoud Pezeshkian said Trump had no justification to ⁠⁠"deprive" Iran of its nuclear ⁠⁠rights. Maryam Jamshidi, a law professor at the University of Colorado in Boulder, said Iran's position on enrichment is based on Article IV of the NPT, "which recognises that all state parties [to the treaty] have the inalienable right to research, develop and use nuclear energy for peaceful purposes". "In demanding that Iran have no enrichment, the United States is denying Iran its rights under this treaty," she told Al Jazeera. "In insisting that its right to enrichment be preserved, Iran is expressing a reasonable desire to be treated the same as any other state under international law." Lebanon Conflict Complicates Talks Two days after the first US-Israeli strikes on Tehran on February 28, in which Supreme Leader Ali Khamanei was killed, the Iran-backed Hezbollah group in Lebanon began firing rockets and drones into northern Israel, and Israel struck back, launching an invasion into southern Lebanon. Iran is adamant that its ceasefire with the US extends to Lebanon and is demanding Israel end its offensive against its ally Hezbollah and its invasion of Lebanon. After initially denying the two-week ceasefire included Lebanon, Israel accepted a 10-day truce starting on Thursday night after direct Israel-Lebanon talks. However, that ceasefire is also teetering on collapse amid renewed hostilities. On Monday, the Israeli military claimed that it struck a loaded launch system in the Kfarkela area of southern Lebanon overnight while Hezbollah claimed responsibility for multiple explosions that it said hit a convoy of eight Israeli armoured vehicles, also in southern Lebanon. Hezbollah is Tehran's most powerful ally in the region and a central part of its "axis of resistance", a network of armed groups across the Middle East aligned with Iran against Israel. The network also includes Yemen's Houthis and a collection of armed groups in Iraq. Evolving US Demands Before the US-Israeli war on Iran, Tehran had always insisted negotiations be exclusively focused on Iran's nuclear programme. US demands, however, have extended beyond the nuclear file. Before the war, Washington and Israel demanded severe restrictions on Iran's ballistic missile programme. Iran has said its ability to maintain its missile capabilities is non-negotiable. On February 25, US Secretary of State Marco Rubio warned that Iran's refusal to discuss its missile programme was a "big problem". Yet, since the two-week ceasefire was announced on April 8 and the Pakistan-brokered negotiations began, the US has not made any mention of Iran's ballistic missiles, which have been a major feature in Iran's retaliation against US and Israeli forces. Regime Change and Proxy Support The US and Israel have also made no secret of their desire for a change in Iran's government. Asked two weeks before the war began if he wished for a toppling of the government in Tehran, Trump said: "Seems like that would be the best thing that could happen." After the killing of Khamenei and multiple other senior Iranian leaders, Trump claimed the US-Israel war had in effect brought about "regime change", claiming key leadership layers were "decimated". Experts, however, disputed Trump's assertions, saying the government was very much intact, if not stronger. Salar Mohandesi, a professor at Bowdoin College in Maine, argued that despite US claims, what is happening in Iran does not meet any serious definition of "regime change". "The fundamental structures of the Islamic Republic are intact, and the new leaders are regime loyalists who are arguably more hardline than their assassinated predecessors," he told Al Jazeera. Mohandesi said the war has arguably strengthened the Islamic Revolutionary Guard Corps (IRGC), something that is an "acceleration of an existing" trend and does not necessarily amount to regime change, "certainly not in the way Trump means it". "Trump's declaration that he has succeeded in 'regime change' is just a rhetorical move to try to claim victory where none exists," he added. Proxy Group Support Three days before the war began during his State of the Union address to the US Congress, Trump accused Iran and "its murderous proxies" of spreading "nothing but terrorism and death and hate". The US and Israel have long demanded Iran stop supporting its nonstate allies – primarily Hezbollah in Lebanon, the Houthis in Yemen and a number of groups in Iraq. Tehran to date has refused to enter into any dialogue about limiting its support for these armed groups. But on Friday, Trump claimed Iran had agreed to almost all of the US demands, including support for its proxies. A statement by Iran's Ministry of Foreign Affairs rejected that any such agreement was in place, saying: "The Americans talk excessively and create noise around the situation. Do not be misled!" Prospects for a Breakthrough On Sunday, Iran's top negotiator and speaker of its parliament, Mohammad Bagher Ghalibaf, acknowledged that while "conclusions" had been reached on some issues, "we are far from a final agreement." Analyst Geist Pinfold told Al Jazeera that deep divisions between the US and Iran make a comprehensive deal unlikely in the near term despite some openings created by Trump's shifting positions. "The primary complication that would mean a deal is less likely but also one of the potential curveballs that would make a deal more likely is the Trump administration's equivocations regarding what its red lines actually are," he said. "At the moment, the gaps look insurmountable," Geist Pinfold added, noting that "the best-case scenario would be the extension of the ceasefire rather than the actual deal." The US-Iran talks face major structural obstacles despite growing speculation about a negotiated end to the current crisis, according to Bowdoin College's Mohandesi. "Donald Trump feels that he needs to somehow convert this disastrous defeat into some sort of win," he noted, adding: "It's unclear what that would look like at the negotiating table." On the Iranian side, Mohandesi sees little room for compromise on the core strategic issues. "Iran will absolutely not abandon its missile programme. It will not stop supporting its allies in the region, and it will almost certainly not agree to zero enrichment," he said. The academic questioned whether even a restoration of maritime traffic would constitute meaningful success for Washington. Even if Trump "were to somehow convince Iran to return the Strait of Hormuz to the pre-war status quo, it's unclear how that would be a major win since the strait was open before he started the war", Mohandesi said.

The LAX Arrest and the Scope of the ChargesShamim Mafi, 44, was apprehended at Los Angeles International Airport (LAX) on Saturday, marking a significant escalation in US efforts to curb Iran's global influence operations. Mafi, who became a lawful permanent resident of the United States in 2016, faces a maximum sentence of 20 years in federal prison if convicted. The Department of Justice alleges she acted as a broker for the sale of drones, bombs, bomb fuses, and millions of rounds of ammunition manufactured by Iran and sold to Sudan.Financial Ties: The $7 Million PipelineThe investigation into Mafi reveals a sophisticated financial network designed to bypass international sanctions. Court documents indicate that Mafi and an unnamed coconspirator operated a company called Atlas International Business in Oman. This entity received over $7 million in payments in 2025 alone. Furthermore, the complaint details a specific transaction involving the sale of 55,000 bomb fuses to the Sudanese Ministry of Defence. Crucially, Mafi submitted a letter of intent to Iran’s Islamic Revolutionary Guard Corps (IRGC) to facilitate this purchase.Exacerbating a Humanitarian CatastropheThe trafficking of these weapons has direct and devastating consequences for the people of Sudan. As the civil war between the army and the paramilitary Rapid Support Forces (RSF) enters its fourth year, the United Nations has warned that the country is at risk of slipping into “full-scale famine and collapse.” By funneling weapons to the Sudanese army—backed by Iran—Mafi’s alleged actions are prolonging the violence. UN officials have stated that weapons from outside sources deserve part of the blame for the crisis, complicating diplomatic efforts to stabilize the region.Geopolitical Ramifications and Future OutlookThis case highlights the deepening entanglement of regional powers in Sudan's conflict. While the United Arab Emirates is often accused of arming the RSF, Mafi's indictment provides concrete evidence of Iran's direct involvement through a US-based conduit. The conviction of a resident for such high-level sanctions evasion suggests a tightening of legal pressure on Iran. Moving forward, this case will likely serve as a precedent for increased scrutiny of financial transactions involving third-party nations like Oman and the monitoring of dual-use technologies.

President Donald Trump announced that a U.S. negotiating team will travel to Islamabad, Pakistan on Monday for a second round of talks with Iranian officials. The move follows a failed session led by Vice President JD Vance and comes as the two‑week cease‑fire, set to expire on Wednesday, is under strain.The administration’s ultimatum – “knock out every single power plant and every single bridge in Iran” – signals a potential escalation that could cripple Iran’s electricity grid, which supplies roughly 20 million people. If all 23 power plants (the approximate number in Iran’s grid) were disabled, the immediate loss of electricity could translate into an economic shock of several billion dollars, given the country’s $150 billion annual GDP.Iran’s foreign ministry, via spokesman Esmaeil Baqaei, condemned the U.S. naval blockade as “unlawful and criminal,” labeling it a war crime. The blockade has already forced 23 ships to turn around, according to U.S. Central Command, tightening pressure on the strategic Strait of Hormuz.Key developmentsMonday – U.S. delegation departs for Islamabad.Tuesday – Expected phone call between Pakistan’s Foreign Minister Mohammad Ishaq Dar and Iran’s Foreign Minister Abbas Araghchi.Wednesday – Two‑week cease‑fire expires; risk of renewed naval confrontations.Iranian officials, including Deputy Foreign Minister Saeed Khatibzadeh and Parliament Speaker Mohammad Bagher Ghalibaf, warned that “significant gaps” remain and described U.S. nuclear demands as “maximalist.” The IRGC Navy announced the re‑closure of the Strait of Hormuz, stating it will stay shut until the blockade is lifted.Takeaway: The upcoming Islamabad talks are a critical diplomatic juncture. Failure to reach a deal could see the U.S. expand its blockade, further disrupt global oil flows through the Strait of Hormuz, and potentially trigger large‑scale infrastructure attacks in Iran.

Key BackgroundThe Strait of Hormuz channels about 21 million barrels of oil per day, roughly 20% of world oil trade. A complete shutdown would cut global supply by around 5%, potentially adding $10‑$15 per barrel to crude prices.What Iran Has SaidAbbas Araghchi (Iranian Foreign Minister) announced the strait would stay open for commercial traffic until the cease‑fire ends on April 22.The Islamic Revolutionary Guard Corps (IRGC) later reversed this, declaring the waterway under "strict management" and warning that it will remain "tightly controlled" until the U.S. restores full navigation freedom.Mohammad Bagher Ghalibaf, Iran's Speaker of Parliament and chief negotiator, called the U.S. blockade "ignorant" and said Iran will not allow passage without its consent.What the United States Has SaidDonald Trump (U.S. President) vowed to keep the blockade until a deal is finalized, warning that failure to accept a "fair" offer could lead to "knocking out every single power plant and bridge" in Iran.Trump announced that U.S. negotiators will travel to Islamabad, Pakistan to seek a settlement.In a Truth Social post, he accused Iran of violating the cease‑fire and promised "very good" talks.Current Situation in the StraitLloyd’s List reports that traffic has halted after Iranian forces fired on several vessels on Saturday.The UK Maritime Trade Operations agency confirmed a tanker was hit by two gunboats linked to the IRGC.India summoned the Iranian ambassador after two Indian‑flagged ships were reportedly fired upon.Broader Sticking PointsNuclear EnrichmentThe U.S. claims Iran’s enriched uranium stockpiles (about 440 kg) constitute "nuclear dust" that Washington will retrieve. Iran’s President Masoud Pezeshkian rejected the claim, asserting Iran’s nuclear program is civilian and compliant with the NPT.Lebanon FrontA fragile cease‑fire in Lebanon, tied to Iran’s demand, remains under pressure. Hezbollah, Tehran’s regional ally, denounced the truce as an "insult" and warned of continued resistance.Potential ImpactIf the strait remains closed, the immediate effect would be a 5‑10% rise in global oil prices, pressuring economies already coping with post‑pandemic recovery. Financial markets could see a $200‑$300 billion hit to oil‑related equities, while shipping insurers would likely raise premiums for Gulf transits.Analysts warn that escalation could trigger broader military engagement, drawing in regional powers and further destabilising global energy supplies.

The Strait of Hormuz has been closed again amid the ongoing standoff between Iran and the United States. Iranian parliamentary speaker Mohammad Bagher Ghalibaf indicated that a conclusive peace agreement is still far away, despite some progress in talks.Iran's Islamic Revolutionary Guard Corps (IRGC) warned that any attempt to pass through the strait without permission will be considered cooperation with the enemy, and the offending vessel will be targeted. The current two-week ceasefire is set to expire on Wednesday unless it is extended.US President Donald Trump has no justification to deprive Iran of its nuclear rights, Iranian President Masoud Pezeshkian said. Iran's valiant navy is ready to inflict new bitter defeats on its enemies, Supreme Leader Mojtaba Khamenei said.The US military forced 23 ships to turn around near the Strait of Hormuz since imposing a naval blockade on Iranian ports. Trump accused Iran of getting a little cute with its recent moves and warned Tehran not to try to blackmail Washington.In Israel, another soldier was killed in combat in southern Lebanon. The Israeli military established a so-called yellow line in southern Lebanon, similar to a measure in the besieged Gaza Strip.United Nations Secretary-General Antonio Guterres condemned the attack that killed a French soldier serving with the UN mission UNIFIL in Lebanon.

US President Donald Trump's recent announcements about securing major concessions from Tehran have sparked rejections and clarifications from Iranian authorities. Trump claimed that Iran had agreed to stop enriching uranium on its soil and would jointly dig up enriched uranium buried under the rubble of bombed Iranian nuclear sites with the US.The Iranian government quickly responded to Trump's claims, with Parliament Speaker Mohammad Bagher Ghalibaf rejecting all of them. The Khatam al-Anbiya Central Headquarters of the Islamic Revolutionary Guard Corps (IRGC) also released a statement saying the Strait of Hormuz is once again heavily restricted and under 'strict management' of the armed forces.The dissonance was clearly on display on state television and other state-linked media, with multiple hosts and analysts harshly attacking Foreign Minister Abbas Araghchi for tweeting that the Strait of Hormuz was 'declared completely open for the remaining period of ceasefire'. The Iranian economy continues to suffer, with oil prices dropping and the Iranian currency experiencing volatility.

Iran's Islamic Revolutionary Guard Corps (IRGC) Navy declared the Strait of Hormuz closed on Saturday, April 18, 2026, warning that any vessel attempting passage would be targeted. The announcement came less than 24 hours after the waterway had been briefly reopened, reigniting concerns over maritime security in the Persian Gulf and the broader U.S.-Iran standoff.The IRGC statement, relayed by Iran's Student News Agency, stipulated that the closure would remain in effect until the United States lifts its naval blockade on Iranian vessels and ports—a move Tehran labels a breach of the cease‑fire agreement linked to the ongoing U.S.-Israel conflict with Iran.Speaker of Iran's Parliament Mohammad Bagher Ghalibaf emphasized on television that “the Strait of Hormuz is under the control of the Islamic Republic,” condemning the U.S. blockade as “clumsy and ignorant.” Meanwhile, Supreme Leader Mojtaba Khamenei warned the navy was prepared to deliver “new bitter defeats” to its adversaries.Just hours earlier, Iranian Foreign Minister Abbas Araghchi had announced the strait “completely open for all commercial vessels,” prompting a brief surge of more than a dozen merchant ships and a dip in global oil prices. The sudden reversal underscores the volatility of the region’s energy markets, where even short‑lived openings can sway price benchmarks.According to the United Kingdom Maritime Trade Operations (UKMTO), Iranian gunboats fired on two commercial vessels, and India’s Ministry of External Affairs confirmed that two Indian‑flagged ships were involved in a “shooting incident.” Some merchant crews reported receiving radio warnings from the IRGC Navy that no ships would be permitted through the strait.U.S. President Donald Trump responded by stating Tehran could not “blackmail Washington” and warned that the naval blockade would “remain in full force” unless a cease‑fire deal is secured before its Wednesday deadline. Trump also hinted at ending the cease‑fire if Iran persists with the closure.Al Jazeera analysts described the situation as “two competing blockades,” noting that the brief reopening had raised hopes for a confidence‑building measure, only to revert to a stalemate. Correspondent Zein Basravi observed that the strait has become “the only space for engagement,” even if that engagement is hostile, serving as a platform for Iran to signal leverage to the United States.
