Two explosions targeted a busy market in the town of Maiduguri in northeast Nigeria, leaving several people dead and injured. Eyewitnesses said that at least 10 people were killed and that more were feared trapped under rubble. Maiduguri is the headquarters of a military force fighting against the Boko Haram Islamist group, which has stepped up its attacks in the area. No group has yet claimed responsibility for the attack. Eyewitnesses said that the attack was carried out using a car bomb at a crowded market near the airport. The second bomb went off two minutes later as neighbours arrived to help the victims.
