"When I received the devastating news of the attack on the school and the fact that the local authorities could not account for all the students, I immediately dispatched a high-level delegation on a fact - finding visit to the town.
"I also instructed the security agencies to deploy in full and not spare any effort to ensure that all the girls are returned safely, and the attackers arrested and made to face justice.
"The entire country stands as one with the girls' families , the government and the people of Yobe State .
"This is a national disaster. We are sorry that this could have happened and share your pain . We pray that our gallant armed forces will locate and safely return your missing family members.
