'Toy bombs' are mortar shells lying abandoned in the province, especially along the areas bordering Afghanistan, often mistaken by children for a toy. On Friday, the student who had taken the toy bomb inside his classroom dropped it on the floor, resulting in the explosion. Police said the injured students were immediately shifted to a hospital in Peshawar, where they were provided treatment and later discharged.
