Nigeria’s army says it has rescued dozens of kidnapped women and children held captive by the Islamic extremist group Boko Haram.

In a statement late Tuesday, the army said it had cleared Boko Haram camps in northeastern Borno state.

Hundreds of hostages have been freed from Boko Haram captivity this year but none of the 219 girls abducted in April 2014 from a school in Chibok were among those rescued.
