Suspected Islamist militants killed 10 Christians in an overnight machete and gun attack in the remote village of Chibok in Nigeria's Borno state on Dec. 2, BBC News reports. Residents said a group of men went from house to house in a largely Christian area of Chibok, setting people's houses on fire before slitting the throats of 10 people. Later, gunmen attacked government targets and churches near the border with Cameroon, killing five policemen. It is still unclear who is behind the attacks, but the army suspects the Islamist sect Boko Haram, which has targeted churches and government establishments in the region in the last few years, killing more than 3,000. The group is fighting to overthrow the government and impose a strict form of sharia, or Islamic law.
