"We have killed all the children in the auditorium...What do we do now?" one of the Taliban attackers told his handler after shooting indiscriminately at the students in the main hall of the army-run school from where more than 100 bodies were recovered. "Wait for the army people, kill them before blowing yourself," his handler ordered, instructing the suicide attackers who were executing one of the most gruesome attacks against children in recent history.It was one of the last conversations between the attackers and their handler on Tuesday shortly before two remaining suicide bombers charged towards the commandos positioned just outside the side entrance of the Army Public School's administration block.
