The army's claiming massive gains against Boko Haram militants. It says airstrikes killed hundreds of militants, and that Boko Haram leader Abubakar Shekau has likely been wounded. That's according to the airforce chief of staff. The strikes took place in Sambisa forest, where Boko Haram has been holed up. The army has in the past claimed its killed Shekau, but he's known for his videos refuting those claims.
