Fourteen people were killed and 39 others injured in four suicide bombing attacks in the northern Nigerian city of Maiduguri late Thursday, the army said.
Details of the attack are still sketchy and the death toll may rise, army spokesman Sani Kukasheka Usman said in an e-mailed statement. Four militants detonated explosive vests simultaneously, he said.
“I heard about four consecutive explosions not far from Gomari area,” a resident, Mohammed Balami, said by phone from Maiduguri.
At least 55 people were killed by three bomb blasts in Maiduguri on Sept. 21.
Militants killed 11 people on Wednesday in attacks on communities in the northeastern Nigerian state of Adamawa, a former council chairman of the Madagali local government area, Maina Ularamu, said by phone.
Nigerian President Muhammadu Buhari has ordered the security forces to step up the fight against Boko Haram’s six-year insurgency. The troops are backed by a multinational force combining soldiers from Cameroon, Chad and Niger -- countries that have faced attacks by Islamist fighters.
