Suicide bombers attacked a church inside a military barracks in Kaduna state in northern Nigeria, killing at least 30 people and injuring at least 45 others. According to ASSIST News, a military spokesman said two vehicles were driven into the barracks in Jaji in what he described as "surprising and an embarrassment." A bus entered the barracks and was driven into the wall of the church, where it exploded. Ten minutes later, a car blew up outside the church. "The first blast caused no casualties, and curious worshipers gathered around the scene looking at the debris ... and that was when the second blast happened," the spokesman said. It is not clear who is responsible for the attack, but the army suspects the Islamist militant group Boko Haram, which has recently targeted churches in the state. The group is fighting to overthrow the government and impose a strict form of sharia, or Islamic law.
