More than 620,000 Rohingya refugees have fled to Bangladesh from Burma’s Rakhine state in the last three months. At least 40,000 unaccompanied children were among those to cross the border, some presenting with bullet wounds. Nearly 60 per cent of Muslim villages in the north of Rakhine have been partially or wholly burned down. Survivors have accused Burma’s military of indiscriminate murder and sexual violence. The army carried out a devastating crackdown after Rohingya militant attacks on security posts in late August.
