The United Nations has raised the alarm over the disappearance of two boats carrying more than 500 Rohingya people off the coast of Myanmar, with both vessels believed to have capsized and survivors considered unlikely. The UN's International Organization for Migration (IOM) and refugee agency UNHCR said in a joint statement that preliminary information indicates the two boats departed from Rakhine state — a conflict-ravaged region in western Myanmar — on 29 June, carrying mainly members of the country's predominantly Muslim Rohingya minority. One vessel, believed to have been carrying around 250 people, lost contact shortly after departure. A second, reportedly carrying about 280 people, is thought to have sunk off Myanmar's Ayeyarwady coast on 8 July. The Bangladesh authorities have recovered the body of one woman washed ashore, while fishermen working between the Irrawaddy delta and the coast of Mon state found several other bodies days later.

The boats departed from Sin Tet Maw, a village now under the control of the Arakan Army — an insurgent group that has driven Myanmar's military from most of Rakhine state and is currently besieging the state capital Sittwe. The ongoing war has severed almost all telecommunications in the region, making it extraordinarily difficult to piece together what happened. Investigators believe the timing was a significant factor: the journeys took place outside the regular sailing season, during the monsoon, when seas are rough and conditions far more hazardous. The vessels themselves were likely old fishing trawlers converted to carry the maximum number of people, with unreliable engines and barely seaworthy hulls. Recent torrential rain and flooding across the region compounded the danger.

The two boats were part of a broader smuggling operation running a well-established route: passengers, who pay around $3,000 each, are transported south along Myanmar's coast, then moved overland through Thailand toward Malaysia, where some 200,000 Rohingya already live. The smuggling networks span Bangladesh, Myanmar, Thailand, Malaysia and Indonesia, and are known for extreme brutality — those whose families fail to pay can be detained and beaten, with videos of their suffering sent to pressure relatives. Researchers estimate that at least 10,000 Rohingya have left Myanmar and Bangladesh by boat since September of last year, a sharply higher figure than in previous years.

The scale of desperation driving these journeys reflects conditions described as increasingly untenable on both sides of the border. In Bangladesh's Cox's Bazar — home to more than a million Rohingya refugees living in overcrowded camps — aid funding is diminishing, employment is virtually non-existent, and organised crime operates with impunity. Those remaining in Rakhine face a military junta accused of forced conscription and an Arakan Army that distrusts the Rohingya and has itself been accused of serious human rights violations against them. Nearly 900 Rohingya were reported missing or dead at sea in the northern Indian Ocean last year alone, out of more than 6,500 who attempted such crossings.

IOM and UNHCR called urgently for enhanced search and rescue efforts, greater action against smuggling and trafficking networks, and access to asylum and protection for those fleeing. The agencies praised Bangladesh for its longstanding generosity in hosting Rohingya refugees, while stressing the need for sustained international support and, crucially, for efforts to address the root causes of displacement. No country in the region has so far shown willingness to open safe and legal pathways for the Rohingya, leaving the most desperate with no option but to place their lives in the hands of criminal networks and the mercy of monsoon seas.
