The Shadow Fleet's Triumph in HormuzOn March 11, the Thai cargo ship Mayuree Naree was struck by two projectiles while crossing the Strait of Hormuz, one of the world's most important waterways located between Iran and Oman. A fire broke out in the engine room, and while 20 sailors were rescued, three remained trapped inside the stricken vessel. Their remains were found weeks later when a specialised rescue team boarded the vessel, which had run aground on the shores of Iran's Qeshm island.At about the same time, a "shadow fleet" of tankers continued to navigate the very same waters safely. Operating with fake flags, disabled signals and unspecified destinations, this covert armada survived because it operates outside the traditional rules of maritime trade.Iran threatened to block "enemy" ships passing through the Strait of Hormuz – a crucial chokepoint for a fifth of the world's oil – in the wake of the United States-Israeli war launched on February 28. Soon, navigation through the strait was disrupted amid fears of attacks.Following a temporary ceasefire on April 8, the United States imposed a full naval blockade on Iranian ports on April 13. Theoretically, traffic through the strait should have come to a complete halt.However, tracking data reveals a remarkably different reality.How Iran's Covert Maritime Network OperatedAn exclusive Al Jazeera open-source investigation tracked 202 voyages made by 185 vessels through the strait between March 1 and April 15, navigating both under fire and across blockade lines.To understand how the strait operated under extreme pressure, Al Jazeera's Digital Investigative Unit monitored the waterway daily, cross-referencing vessel International Maritime Organization (IMO) numbers with international sanction lists from the US Office of Foreign Assets Control (OFAC), the European Union, the United Kingdom and the United Nations. An IMO number is a unique seven-digit figure assigned to commercial ships.Of the tracked voyages, 77 (38.5 percent) were directly or indirectly linked to Iran. Notably, 61 of the ships transiting the strait were explicitly listed on international sanctions lists.The investigation divided the conflict into three distinct phases to map the fleet's behaviour:Phase 1: Open War (March 1 – April 6): 126 ships crossed the strait, peaking at 30 vessels on March 1. Among these, 46 were linked to Iran.Phase 2: The Truce (April 7 – 13): 49 ships crossed during this fragile pause. More than 40 percent of these vessels were tied to Iran, including the US-sanctioned, Iranian-flagged Roshak, which successfully exited the Gulf.Phase 3: The US Blockade (April 13 – 15): Despite the explicit naval blockade, 25 ships crossed the strait.Breaking the Blockade: Tactics and TechniquesWhen the US blockade took effect, the shadow fleet adapted immediately.The Iranian cargo ship "13448" successfully broke the blockade. Because it is a smaller vessel operating in coastal waters, it lacks an official IMO number, allowing it to evade traditional sanction-monitoring tools. The vessel departed Iran's Al Hamriya port and reached Karachi, Pakistan.Similarly, the Panama-flagged Manali broke the blockade, crossing on April 14 and penetrating the cordon again on April 17 en route to Mumbai, India.The investigation uncovered widespread manipulation of Automatic Identification System (AIS) trackers. Vessels such as the US-sanctioned Flora, Genoa and Skywave deliberately disabled or jammed their signals to hide their identities and destinations.The Global Network Behind Fake FlagsTo obscure ultimate ownership, the shadow fleet heavily relies on a complex web of "false flags" and shell companies. The investigation identified 16 ships operating under fake flags, including registries from landlocked nations like Botswana and San Marino, as well as others from Madagascar, Guinea, Haiti and Comoros.The operational network managing these ships spans the globe. Operating firms were primarily based in Iran (15.7 percent), China (13 percent), Greece (more than 11 percent) and the United Arab Emirates (9.7 percent). Notably, the operators of nearly 19 percent of the observed vessels remain unknown.Economic Impact on Global Energy MarketsDespite the intense military pressure, energy carriers dominated the traffic, with 68 ships (36.2 percent) transporting crude oil, petroleum products and gas. Ten of these tankers were directly linked to Iran. Non-oil trade also persisted, with 57 bulk and general cargo ships crossing during the open war phase, 41 of which were tied to Tehran.Before the war, at least 100 ships crossed the Strait of Hormuz daily. Today, a staggering 20,000 sailors are trapped on 2,000 ships across the Gulf – a crisis the International Maritime Organization described as unprecedented since World War II.A shadow Iranian fleet, meanwhile, has been navigating seamlessly as part of a parallel maritime system born from 47 years of US sanctions on Tehran. Washington slapped sanctions on Tehran following the 1979 Islamic revolution that toppled the pro-Washington ruler Shah Mohammad Reza Pahlavi. The two countries have had no diplomatic ties since 1980.Future Implications for Global Trade and SanctionsThe success of Iran's shadow fleet in evading the US naval blockade demonstrates the limitations of traditional sanctions and naval blockades in the modern era. As technology enables more sophisticated evasion techniques, international bodies may need to develop new monitoring and enforcement mechanisms to maintain effective sanctions regimes.The persistence of trade through the Strait of Hormuz, despite military conflict and blockades, underscores the critical importance of this waterway to global energy markets. Any prolonged disruption would have significant economic implications worldwide, potentially accelerating efforts to develop alternative trade routes and energy sources.Meanwhile, the humanitarian crisis affecting thousands of sailors stranded in the Gulf highlights the unintended consequences of geopolitical conflicts on civilian maritime operations, potentially prompting new international agreements on protecting neutral shipping during conflicts.

The LeadMadagascar has taken significant diplomatic and legal actions against French nationals, detaining a former French serviceman and expelling a French embassy agent over allegations of a destabilization plot against the island nation. The move has escalated tensions between Madagascar and France, the country's former colonial power.The Event DetailsAccording to Deputy Prosecutor Nomenarinera Mihamintsoa Ramanantsoa, the former French national serviceman, Guy Baret, has been placed in pretrial detention at Tsiafahy maximum-security prison. A Malagasy army officer, Colonel Patrick Rakotomamonjy, and other alleged accomplices have also been implicated in the plot.The suspects are accused of planning actions initially set for April 18, targeting the stability of Madagascar's government led by President Michael Randrianirina, who seized power in October 2025 following protests against his predecessor.The Legal ChargesProsecutors have formally charged the suspects with several serious offenses:Spreading false information to disturb public orderPlotting to sabotage infrastructure including power lines and thermal plants operated by state utility JiramaHarboring wanted individualsCriminal conspiracyRakotomamonjy is awaiting presentation before an investigating judge, while two other suspects have been placed under judicial supervision, with prosecutors indicating they were not the masterminds of the conspiracy.The Diplomatic ResponseFrance has strongly rejected the accusations, summoning the charge d'affaires of the Madagascan embassy in Paris "to vigorously protest" the expulsion of the diplomatic official. French Foreign Ministry spokesman Pascal Confavreux stated that France "categorically rejected any accusation of destabilising the Refoundation regime of the Republic of Madagascar," calling the accusations "unfounded" and "incomprehensible."In response, Madagascar's Foreign Ministry confirmed that French Ambassador Arnaud Guillois had been summoned and informed of the decision regarding the embassy agent, though the agent's identity and specific alleged acts were not disclosed.The Regional ContextThe incident occurs against a backdrop of political instability in Madagascar, a former French colony that maintains close political ties to France. The country has experienced multiple power changes in recent decades, with President Randrianirina taking control after youth-led protests forced his predecessor, Andry Rajoelina, from power in October 2025. Notably, France assisted Rajoelina's departure during the escalating protests over water and energy shortages.This diplomatic confrontation adds to regional tensions in the Indian Ocean and Africa, where former colonial powers and African nations continue to navigate complex post-colonial relationships.

The LeadMadagascar has long been celebrated for its remarkable wildlife, with the vast majority of its species found nowhere else on the planet. But when discussing the island nation's endemic treasures, fungi are often left out of the conversation, despite their critical importance to life on Earth.The Fungal Frontier"Fungi are some of the most important things in the world," says Anna Ralaiveloarisoa, a Malagasy scientist and the first homegrown mycologist in Madagascar. "They feed 90% of terrestrial plants. Without them, there is no life on the Earth." Ralaiveloarisoa is working to classify each of the 200 new species she has identified so far, though she faces significant challenges: trying to preserve mushrooms without proper infrastructure; journeying to remote spots in the jungle without reliable roads or electricity; and having no other experts to collaborate with in the country.Less than 1% of the estimated 100,000 species of fungi in Madagascar have been scientifically described, highlighting the vast unknown territory that remains to be explored.The Conservation MovementAcross the globe, protecting fungi has lagged significantly behind the conservation of plants and animals. While the first organisations dedicated to protecting birds were established in the 19th century, fungi had to wait until the 21st century. The International Society for Fungal Conservation (ISFC) was established in 2010, and the first conservation nonprofit organisation, the Fungi Foundation, was created in 2012.Since those groups were established, a global movement has emerged. The first conservation legislation to include fungi was passed in Chile in 2013. The Fungi Foundation began to champion the phrase "fauna, flora, funga" to encourage fungi's inclusion in more conservation frameworks.The African ConnectionThough the obstacles are significant, they are ones Ralaiveloarisoa shares with many mycologists in nearby nations. She is part of an emerging cohort of scientists across Africa who are pioneering the study and conservation of fungi in their home countries.Last November, many met for the first time at the International Congress on Fungal Conservation, held in Cotonou, Benin. The conference drew mycologists from 27 countries across Africa, Europe, the Americas and Asia, with several hailing from African countries where they serve as the only – or one of very few – mycologists in the nation."What an exciting time: from almost nothing 20 years ago, fungal conservation has evolved from a little-known field into a dynamic global movement," said Nourou Yorou, a mycologist who was recently named general director of the Benin Agency for Science and Innovation. "The challenge is now to plan a future where fungi are firmly placed in the conservation mainstream."The Future OutlookThe momentum behind fungal conservation continues to grow. Other organisations have formed: in 2017, North America's first fungal conservation nonprofit group, Fundis, was created; in 2021, the research organisation SPUN (Society for the Protection of Underground Networks) was cofounded by the evolutionary biologist Toby Kiers.Later this year, the "fungal conservation pledge" first proposed at the UN biodiversity meeting of Cop16 in Colombia in 2024 will be discussed again at the forthcoming biodiversity conference in Armenia. As David Minter, president of the ISFC, notes: "In 2010, it was normal not to mention fungi at all in conservation ... In the future it will look strange if fungi don't get a mention."
