Pakistan troops resorted to heavy overnight shelling in various sectors at the International Border in Jammu and Kashmir, targetting several Border Security Force or BSF posts. The Director General of the BSF is scheduled to go to Jammu today and visit the forward areas to take stock of the situation. Yesterday, 15 Indian posts came under fire from the Pakistan Rangers in the Samba and Hiranagar sectors. One BSF jawan who was injured in the firing later succumbed to his injuries.
