KANO  - A suicide bomber in a car rammed into a military patrol on Sunday in the northeastern Nigerian city of Damaturu, killing himself and at least five soldiers, a security source said. “The attacker died in the explosion and five soldiers were also killed,” the source said on condition of anonymity. There was no immediate claim for the attack, but it was similar to scores of others carried out by radical Islamist group Boko Haram, whose insurgency has killed hundreds in Nigeria. The state police commissioner, Patrick Egbuniwe, confirmed the explosion and said that there were military casualties, without providing a figure.

He provided a slightly different version of events, saying the suicide bomber was being chased by a military patrol vehicle and the driver blew himself up when soldiers closed in on him. However, the security source said the bomber in a sport-utility vehicle had been parked along the roadside and rammed into the multiple vehicle military convoy when it passed, affecting two of the vehicles. Damaturu is located in Yobe state, which has been hard hit by attacks blamed on Boko Haram. Sunday’s attack follows a suicide bomber’s attempt to assassinate Yobe state’s top traditional Muslim leader, the Emir of Fika, on Friday.
