| Relations between India and Pakistan have deteriorated in recent months |
The Indian army has vowed "heavy
retribution" for the killing of its three soldiers in the disputed
region of Kashmir on Tuesday.
Tensions over the long-running dispute have intensified after an Indian army base was attacked in September. Both India and Pakistan accuse each other of violating the 2003 ceasefire agreement.
Both sides have reported civilians and a number of soldiers being killed or injured in recent weeks, during which time the Line of Control (LoC), the de facto border that divides disputed Kashmir between the two nations, has seen intense exchanges of fire.
Both nuclear-armed states claim the territory in its entirety but control only parts of it. Two of the three wars fought between the two sides since independence have been over Kashmir.
Following the latest attack, there was heavy firing and shelling by both sides of the LoC in Machil, reports said. "Retribution will be heavy for this cowardly act," Col Kalia said.
An Indian army officer told the Press Trust of India news agency that a "counter-infiltration patrol party of Indian army was ambushed by terrorists ahead of the fencing along the Line of Control in the forest belt in Machil sector in Kupwara district" on Tuesday. He did give any further details.
