The military said 219 of the 276 Chibok schoolgirls kidnapped by Boko Haram in April are still missing. During the attack, an additional 119 girls managed to avoid being abducted by the terror group, and 57 girls subsequently escaped their captors. A southern delegate noted the recent arrest of 486 suspected Boko Haram members traveling at night in 35 buses in Abia state, and recommended that security be heightened around oil installations in Port Harcourt and elsewhere in Rivers state; a northern delegate warned security agencies of possible retaliation by northern states.
