Police say at least 10 people have been killed in an attack in northeast Nigeria that targeted a church and a local market.

The attack occurred Sunday in Njilan, a village in Adamawa state.

Adamawa state police spokesman Muhammad Ibrahim said that six people had been killed in the market, while another four were killed around the church. Ibrahim could not immediately offer a motive for the attack, nor could he say whether police had any suspects in the violence.

Northeast Nigeria has faced increasingly bloody attacks by Islamic extremists since 2010. While the government has deployed more soldiers and police in the region, the attacks by the extremist network Boko Haram, splinter groups and others continue.
