Nigerian troops combating Boko Haram militants have killed top commander Abu Mojahid in northern Nigeria's Borno State, a military spokesperson said Wednesday.

Spokesperson for the Nigerian Defense Headquarters Major General Chris Olukolade said that the commander and other militants had staged a daring attack on troops who were on patrol on the outskirts of Alagarno area on Tuesday.

He said a number of militants died as the troops repelled the attack, adding that some Rocket Propelled Grenades as well as vehicle mounted Anti-Aircraft guns were either captured or destroyed in the encounter.

Olukolade said the military operations are continuing in the form of offensive action on identified militants in some forest locations.
