By the Saturday the full horror of what had taken place at the school became clear.
Emergency workers, sifting through the debris of the burnt out gymnasium, uncovered the remains of some of the hundreds of children and adults killed.
The siege left 331 people dead, including 186 children. More than 700 people were injured.
Many of the bodies were charred beyond recognition and some parents had to wait for DNA tests to confirm the fate of their children.
