LAGOS, March 7 (Xinhua) -- Over 200 people were killed and others seriously injured on Sunday in a fresh riot which erupted in Jos, the capital of northern Nigeria's Plateau State, resident and police have said.

The development came after more than 300 people died during the crisis that erupted on Jan. 17 in the northern city of Jos in Plateau State, when some youths attacked worshippers at St. Michael's Anglican Church in Nasawara Gwom.

A resident of Jos, David Kyang, said the group that attacked the village came in the early hours of the day.

"They came and attacked us when everyone slept; they first set the houses ablaze and shot sporadically into the air to scare the able-bodied men away," he told reporters.

He also alleged that the group equally stormed a nearby village, Ramsat.

The chief medical director of the Plateau Specialist Hospital, Pam Datong, said many of the victims, who sustained various forms of injuries, were receiving treatment at the hospital.

Speaking in the same vein, Chairman of Jos South Local Government, Moses Dalyop, described the group that perpetrated the acts as heartless and barbaric.

"They are inhuman,'' he said.
