In the wake of the attack, Khan postponed his plan to shut down the entire country that was planned for December 18.
Shagufta, who lives near the school, told Geo TV that she heard two explosions, a smaller one followed by a huge bang.
A student who identified himself as Shuja told Samaa TV that they were taking examination when firing started.
They were told by the teacher to lie down on the floor. He said they remained on floor for about one hour when army soldiers came and told them to go out.
Several students escaped through the back gate. One of students who escaped told Dunya TV that fourth period was in progress when they heard firing.
