Both the Pakistani Taliban and Lashkar-e-Islam have been battling for control of the valley.

Earlier, Pakistani officials said militants in the same area clashed with security forces, leaving at least 10 soldiers and 23 militants dead.

Separately Friday, Pakistani police say gunmen have shot and killed an intelligence official in the northwestern city of Peshawar. It was not immediately clear who shot the official, but Taliban militants have attacked and killed intelligence officials in the area.
