A female suicide bomber was the only fatality when she exploded a vehicle packed with explosives near a stadium where Nigeria’s president had just held an election rally Monday in the northeastern city of Gombe, police said. The explosion occurred in a near-empty area about 1.5 kilometers (1 mile) from the venue, which President Goodluck Jonathan had just left, said Deputy Superintendent Fwaje Atajiri. Two other suicide bombings in Gombe city on Sunday injured a few people but killed only the bombers, he said. A couple sharing a bicycle blew themselves up at a central traffic circle and a man blew himself up at a timber market. All three bombers died, Atajiri said.
