The Nigerian military last week announced it had retaken the towns of Mongono and Marte near the remote Sambisa forest in Borno state. Authorities vowed to press ahead and defeat the extremist Boko Haram group. A two-minute video posted by the military showed air strikes conducted by the Nigerian Air Force destroying six militant gun trucks. Several others were destroyed in follow-on attacks, as the helicopter gunships continued to strafe fleeing insurgents.
