(The New York Times) – A video released in Nigeria on Monday by Boko Haram purports to show girls among those abducted in 2014 from a school in the town of Chibok vowing to stay with their captors and never go home. About a dozen girls, some with faces covered, appear in the video, one of several released in recent days by Boko Haram, the Islamist group terrorizing northern Nigeria in a war that has spilled across borders and raged for nearly nine years.
