Sri Lankan monks and hard-line nationalists protesters forced 31 Rohingya Muslim asylum seekers to flee a United Nations safe house in the capital Colombo on September 26, police said.
The refugees, who were arrested in April along with two suspected Indian traffickers in a boat in Sri Lankan seas, were taken into protective custody and then to a detention centre outside Colombo, police spokesman Ruwan Gunasekara said.
A live telecast on the Facebook page of Sinhale Jathika Balamuluwa, a hard-line nationalist group, showed the Buddhist monks and some civilians storming the safe house chanting "do not allow terrorists into this country."
The Rohingya group fled Myanmar in 2012 and lived in India as refugees for nearly five years before trying to migrate illegally, a lawyer representing them told Reuters. A local court later handed them over to UN Human Rights Council (UNHRC). UNHRC officials were not immediately available for comment.
