Spotted: Kidnapped Nigerian girls with Boko Haram militants in Gwoza town

London: More than 50 girls who were abducted by Boko Haram militants in Nigeria last year have been seen alive three weeks ago, a woman said.

According to the BBC, she said that the girls were spotted in the north-eastern Gwoza before regional forces drove the Boko Haram militants out of the town.

The militant group sparked global condemnation when it abducted more than 219 girls from the town of Chibok last year.

The United States, China and other world powers promised to help find the girls but they have not been traced so far. Little is known about them since they were kidnapped from their boarding school.
