Four children, aged 7 to 10, and an adult were injured in an explosion in the northwestern Pakistani city of Peshawar early on Tuesday, hospital and rescue officials said.
An explosion targeting police in Pakistan's Dera Ismail Khan city on Friday killed five people and injured 21. There was no immediate claim of responsibility.
The Pakistan government stated that the loud explosion in Dera Ghazi Khan may have been a sonic boom. A primary investigation found no evidence of terrorism, vandalism or accident.
