The parents of the schoolgirls abducted by gunmen in Nigeria's Borno state last Tuesday say the number of children missing is much higher than the authorities admit.

The army put the number at 129, but school officials said more than 200 students were taken during the attack on the Chibok Government Girls Secondary School.

There is still confusion about how many of the girls have escaped and how many remain hostages.

The armed group, Boko Haram, is suspected of being behind the attack and kidnappings, but so far no one has claimed responsibility.
