Since the early 2010s, over a million Rohingyas have found refuge in Bangladesh. A Muslim minority persecuted in their native Myanmar, the Rohingyas suffered the deadliest crackdown by the junta there back in 2017. The UN has described those abuses as genocide. In retaliation, some Rohingyas armed themselves against the junta to defend their community. But in refugee camps in Bangladesh, clashes have been reported between two such Rohingya armed groups, the RSO and the ARSA, leaving refugees caught in the crossfire. Nearly 150 people have been reported killed in the past two years. Our regional correspondents Lisa Gamonet, Nabeel Ahmed and Navodita Kumari report.
