MAIDUGURI, Nigeria, Sept. 6 (Xinhua) -- At least 50 Boko Haram fighters were killed in a raid by the Nigerian army after civilians were slain by the militant sect in the northern state of Borno, the military said on Friday.
The military launched a raid on a camp of the insurgents with the backing of aircraft, dealing a heavy blow to Boko Haram fighters, who were surrounded after killing 15 civilians this week, said Lt.-Col. Sagir Musa, spokesperson of the Nigerian troops.
"Subsequently, the villages have been rescued from the fangs of the insurgents. At the moment, the troops are pursuing the remnants of the fleeing terrorists by blocking all possible exit routes," the military mouthpiece added.
The civilians were killed by the insurgents in two attacks launched on Wednesday and Thursday in Gajiram and Bulablin villages of the northern state.
Boko Haram, based in northeastern Nigeria, seeks to enshrine the Islamic sharia law into the constitution and declares war against the Western education. The Nigerian government tried in April to broker a ceasefire with the sect but failed.
