Four Pakistani soldiers were killed and three others wounded on Thursday when an army patrol was attacked by unidentified assailants in a thickly forested area along the Line of Control in Pakistan-occupied Kashmir. The army patrol, on a routine scouting of the LoC along the Buttle sector of Jajira area, detected some "unknown assailants", on the Pakistani side and they opened fire at the soldiers, military spokesman Maj Gen Athar Abbas said.
