Nigeria: 200 held over killings

Police in Nigeria have arrested around 200 people following weekend attacks on three Christian villages in which hundreds of people were thought to have been killed. The central city of Jos, at the crossroads of Nigeria's Muslim north and Christian south, has been tense since Sunday's attacks, blamed on northern settlers, on the villages of Dogo Nahawa, Zot and Ratsat just south of the Plateau state capital.
