Two jawans were killed and mutilated in Kashmir in unprovoked firing by Pakistan this morning, the army has said, warning of "appropriate response" for the "despicable act." It also retaliated with heavy mortar fire immediately, said sources. The soldiers who were killed -an army jawan and a constable of the Border Security Force or BSF - were part of a team on patrol between two forward posts in the Krishna Ghati sector along the Line of Control when Pakistan fired rockets and mortar bombs, the army said.
