The International Criminal Court prosecutor sought an arrest warrant for Myanmar’s military leader, Min Aung Hlaing, over alleged crimes against humanity tied to the Rohingya crisis.

Karim Khan said after what he described as an extensive, independent and impartial investigation that his office had found reasonable grounds to believe the junta chief bore criminal responsibility for deportation and persecution of the Rohingya committed in Myanmar and in part in Bangladesh. The application now goes to a panel of three ICC judges, who must decide whether to issue a warrant.

The move focuses on one of the most consequential episodes in Myanmar’s recent history. In 2017, more than 700,000 Rohingya fled Rakhine state after a military operation that UN investigators said was carried out with genocidal intent. Many crossed into Bangladesh, where almost 1 million Rohingya still live in Cox’s Bazar, one of the world’s largest refugee camps. The ICC prosecutor’s office has been investigating the violence of 2016 and 2017 for five years.

Khan said his office would make further arrest-warrant applications. The request also lands in a wider accountability effort that has long stalled over Myanmar’s repeated denial of genocide allegations and the limited ability of international institutions to enforce consequences inside the country.

Rights advocates quickly framed the application as overdue. Tun Khin, president of the Burmese Rohingya Organisation UK, called it a huge step forward and said Rohingya communities had waited years for accountability. Nay San Lwin, another Rohingya activist, said the move was warmly welcomed and urged the court to issue a warrant promptly.

The allegations now before the court are specific to deportation and persecution, not the wider universe of abuses documented in Myanmar. But the facts described by Khan’s office and by Rohingya groups point to the same broader pattern: mass displacement, killings, rape, burned villages and sustained pressure on a minority population that has been driven across a border and kept in prolonged insecurity.

Min Aung Hlaing remains at the center of Myanmar’s military rule after the 2021 coup, which followed years of international alarm over the treatment of the Rohingya. The ICC filing does not settle the question of legal guilt. It does, however, mark a formal escalation by the court against a figure rights groups describe as one of the architects of the country’s abuses.

There is no fixed timetable for a judicial ruling, though such decisions generally take about three months. For Rohingya survivors and advocates, the filing itself is the latest sign that international justice mechanisms are still willing to press the case, even if slowly and unevenly, against a leader they say has evaded accountability for too long.
