‘Amnesty International and Bangladeshi officials have slammed Myanmar’s military for using landmines against the Rohingya Muslims fleeing violence at home, causing many of the refugees to sustain serious injures or lose their body organs.

The United Nations says 300,000 Rohingya Muslims have fled to neighboring Bangladesh since the Myanmar military unleashed another deadly campaign against the Rohingya-majority Rakhine State two weeks ago.

Bangladeshi officials and Amnesty International experts believe new landmines have been recently planted, including one that the rights group said blew off a Bangladeshi farmer’s leg and another that wounded a Rohingya man. Both incidents occurred Sunday.

AP reporters in Bangladesh on Monday saw an elderly woman injured by a landmine. She had devastating leg wounds: one leg with the calf apparently blown off and the other also badly injured. Relatives said she had stepped on a landmine.’
