Nigerian security forces failed to act on advance warnings...... Amnesty International

The group spoke as one of the victims’ father told CNN that the insurgents were usually supplied by helicopters.

Speaking with CNN correspondent, Isha Sesay, in Abuja on Friday, he said the matter was reported to the soldiers but nothing came out of it.

AI called on the Federal Government to provide adequate information to families of the abducted girls on its current efforts to ensure their safe release.

It also suggested that “the families – and the abducted girls, once they are freed – must be provided with adequate medical and psychological support.”

He said, “Damning testimonies gathered by Amnesty International reveal that Nigerian security forces failed to act on advance warnings about Boko Haram’s armed raid on the state-run boarding school in Chibok which led to the abduction of more than 240 schoolgirls on 14-15 April.

“The fact that Nigerian security forces knew about Boko Haram’s impending raid, but failed to take the immediate action needed to stop it, will only amplify the national and international outcry at this horrific crime.

“It amounts to a gross dereliction of Nigeria’s duty to protect civilians, who remain sitting ducks for such attacks. The Nigerian leadership must now use all lawful means at their disposal to secure the girls’ safe release and ensure nothing like this can happen again.”

The organisation said it had confirmed through various sources that Nigeria’s military headquarters in Maiduguri “was aware of the impending attack soon after 7pm on April 14, close to four hours before Boko Haram began their assault on the town.”
