A teacher and two children were killed on Wednesday when a hand-grenade attack took place on a school in the Shabqadar area of Peshawar.
Sources said the school had received letters a month earlier which threatened the administration to direct students to wear shalwar kameez instead of pants and shirts.

The explosion resulted in the death of school teacher Madam Honey and injured two children.
