Nigerian troops fought Boko Haram in the Lake Chad area on Saturday, killing 13 of the Islamic extremists and arresting 10 others, including six women believed to have helped smuggle supplies to the insurgents, an army spokesman said.
Meanwhile witnesses said four civilians out hunting for food near a displacement camp in the northeast were beheaded by suspected Boko Haram militants.
Soldiers from the 8 Task Force Battalion spent 72 hours clearing the location where the Boko Haram fighters were hiding, said battalion spokesman Col. Timothy Antigha. Many other Boko Haram fighters were wounded by gunfire, he said.
The troops, operating in the Chikun Gudu, Tumbuma Karami and Tumbuma Baba areas recovered three AK 47 rifles and one pump-action rifle, assorted rifle magazines and 306 rounds of ammunition, a tool box, a freezer and a Toyota truck, he said.
