Rioters continued sporadic attacks, ripping apart homes and setting them on fire, according to reports.

Railway links between Assam and the rest of the country have been disrupted after local people threw stones at an express train travelling through the area, and damaged four coaches, reports say.
A local villager fleeing the violence told local TV channels that people had "lost everything in the violence".
"Our houses have all been razed to the ground with mobs setting ablaze our properties," Rabiul Islam from Kokrajhar district said.
Police say that the clashes began when unidentified men killed four youths on Friday night in Kokrajhar district, an area dominated by the Bodo tribe.
