"Dead bodies were lying everywhere," says Mohammad, one of thousands of Rohingya who have entered Bangladesh in recent months, fleeing what they say is worsening violence in Myanmar. Fighting near the border has escalated and refugees making the crossing say they been targeted by drone and mortar attacks. Experts have pointed to the forced recruitment of Rohingya by armed groups as a cause of what they say are retaliatory attacks on refugees, carried out by rebels fighting against Myanmar's military junta. Around a million Rohingya live in refugee camps in Bangladesh after fleeing a 2017 military crackdown that followed decades of persecution against the Muslim ethnic minority group.
