ISLAMABAD, Pakistan, Nov. 22 (UPI) -- Three people were killed and at least 11 were injured Saturday when an explosion struck a mosque in Pakistan's North-West Frontier province, officials said.

It wasn't clear how many people were inside the Hangu district mosque when the explosion leveled it, a district official told CNN.
