MAIDUGURI, Nigeria (Reuters) - A suicide bomber in a bus killed one member of the civilian joint taskforce (JTF) at the main checkpoint on the outskirts of Nigeria's northeastern city of Maiduguri around midday on Monday, military and JTF sources said.
A JTF member at the scene said that after the passengers had left the bus the driver drove forward to another inspection point at the Njimtilo checkpoint in the southwest of the city where he detonated the bomb. Three civilians were injured.
There was no immediate claim for the attack but it bore the hallmarks of Islamist militant group Boko Haram. Maiduguri, the state capital of Borno, is the birthplace of the jihadi sect.
