Nigeria has been grappling with a long-running insurgency in its northeast region, primarily driven by the extremist armed group Boko Haram and its offshoot, Daesh (ISIL or ISIS) West Africa Province.
In Borno state, suspected militants ambushed and killed 10 civilians and two security officials in an attack on Saturday, said Mohammed Shehu Timta, emir of Borno's Gwoza area. Two others sustained injuries in the attack, Reuters reported.
In neighboring Adamawa state, suspected Boko Haram militants had killed 10 people and wounded several others in an attack against Kopre village, also on Saturday, residents said.
The attack targeted hunters and civilian joint task force (CJTF) members and Adamawa police have deployed additional officers to Kopre, which is in Hong district, police spokesperson Suleiman Yahaya Nguroje said on Monday.
Earlier this month, Borno's governor acknowledged that Boko Haram had renewed attacks and kidnappings, reversing previous gains by security forces.
