Nigerian forces used jets and attack helicopters to bombard Islamist militant camps in the northeast on Friday, killing a number of insurgents, the defense headquarters spokesman said.
Brigadier-General Chris Olukolade told Reuters by telephone several camps had been attacked, including in the Sambisa game reserve in Borno state, but did not have further details.
"A number of insurgents have been killed. It is not just Sambisa, every camp is under attack. But we have not done the mopping up operations on the ground to determine the numbers killed," Olukolade said.
