The governor of Nigeria’s Gombe state on Saturday imposed an around-the-clock curfew after an attack by Boko Haram gunmen, his spokesman said.

“Governor Ibrahim Dankwambo has directed that a 24-hour curfew be imposed on Gombe as a result of the security breach in the city,” Ayuba Aluke said, referring to the state capital of the same name but specifying that the curfew would be in effect statewide.

“By this announcement residents are to remain indoors until further notice as security operatives work to restore law and order in the city,” he said.
