A Malaysian aid ship arrived Monday in Bangladesh carrying aid for hundreds of thousands of Rohingya Muslims who have fled from Myanmar, many citing abuses by the Myanmar security forces.

Nearly 70,000 Rohingya have fled from Buddhist-majority Myanmar's Rakhine state to Bangladesh to escape a crackdown launched after nine policemen were killed in attacks on border posts on Oct. 9 that Myanmar blamed on Rohingya militants.

The U.N. human rights office said in a report this month Myanmar's security forces had committed mass killings and gang rapes of Rohingya Muslims and burned their villages.
