A bomb went off in a school on the outskirts of the northwestern Pakistani city of Peshawar today, injuring three people; two children and a teacher.
The school in Palosai area was badly damaged by the remote-controlled explosive device, police said.
The area is close to the Khyber tribal region, where the banned Tehrik-e-Taliban Pakistan and Lashkar-e-Islam groups are active.
Special Superintendent of Police (Operations) Ijaz Khan told PTI that two students and a teacher sustained minor injuries in the attack.
No group claimed responsibility for the bombing.
The Taliban have bombed scores of state-run schools in northwest Pakistan.
Footage on television showed that the blast had destroyed two rooms of the school and blown up a wall.
Chairs and desks lay strewn in class rooms and the blast also smashed all windows.
Local residents took the injured to a nearby hospital.
Security forces cordoned off the site and launched a search operation for the attackers.
