A car bomb targeting a military checkpoint on a road leading to Nigeria's northeastern city of Maiduguri exploded Tuesday, killing all nine people in the vehicle, police and witnesses said. According to AP, those killed were the driver and passengers in the explosives-laden minivan, said police deputy superintendent Victor Isuku, blaming Boko Haram extremists. Army spokesman Col. Sani Kukesheka Usman put the number of dead at eight. He said the attackers wore "suicide vests" in addition to the car bomb.
