Chibok girls not among group rescued by Nigerian army

200 schoolgirls abducted from their school dormitories by Boko Haram militants last year are not among the nearly 300 girls and women rescued in an army operation on Tuesday, an army spokesman said.

Nigeria's army said it had rescued 200 girls and 93 women on Tuesday during a military operation to wrest back the Sambisa Forest in the northeast from the militant group.

"The troops rescued 200 abducted girls and 93 women," Colonel Sani Usman told Reuters in a text message. They were not, however, from Chibok, the village from which more than 200 girls were abducted in April 2014, he said.
