The Rohingya ethnic minority of Burma are trapped between severe repression in their homeland and abuse in neighboring countries. Bangladesh has hosted hundreds of thousands of Rohingyas fleeing persecution for more than three decades, but at least 200,000 Rohingya refugees have no legal rights there. They live in squalor, receive very limited aid and are subject to arrest, extortion and detention. Unregistered refugee women and girls are particularly vulnerable to sexual and physical attacks. The international community must urge the Bangladeshi government to register undocumented refugees and improve protection for all vulnerable Rohingyas. Donor governments must also work to restart and increase resettlement of refugees to a third country and increase assistance for communities hosting refugees.
