He said heavy firing between the two sides continued for an hour during which Constable Devender Singh was hit by a stray bullet through the loophole of his picket. He was immediately evacuated to a hospital but could not survive, the officer added.
He said intermittent firing between the two sides was still continuing when last reports were received.
The incident came barely 24 hours after BSF noticed suspicious movement of a group of five persons, believed to be terrorists and attempting to sneak into this side, along the IB in Hiranagar sector of nearby Kathua district, prompting a massive search operation and sounding of a high alert in Jammu.
