A rights group, Amnesty International, has said that Boko Haram has abducted at least 2,000 women and girls since the start of 2014.

According to a report published by the organization, many of those captured by Boko Haram have been forced into sexual slavery and trained to fight for the group.

Amnesty International’s secretary-general, Salil Shetty, said that the evidence presented in this shocking report, one year after the horrific abduction of the Chibok girls, underlined the scale and depravity of Boko Haram’s methods.

The publication of the report coincides with the one-year anniversary of the mass abduction by Boko Haram of hundreds of school girls from Chibok town in Borno State.

The abduction of the 276 girls sparked global outrage, and 219 are still held by the group, the others managing to escape.
