21 killed in attacks across central, north Nigeria
Authorities say 21 people have been killed in violence across north and central Nigeria as religious and ethnic tensions continue to simmer in the region.
In Plateau state, where rioting has killed hundreds in recent years, police and activists say at least 17 people were killed in separate attacks overnight Tuesday. The spark of the violence remains unclear, though an advocate says at least 14 of the dead belonged to a Christian ethnic group there. (AP)
