Two other soldiers and a civilian were also wounded in the incident on the Line of Control (LoC) in Krishna Ghati sector in Poonch district in Pakistani shelling as well as firing during the infiltration bid.
The military, however, reported the death of only one Indian soldier.
Defence spokesman Lt Col Manish Mehta had earlier told IANS that the Army prevented the infiltration bids on Saturday night.
“Alert and vigilant troops observed suspicious movement and challenged the infiltrators. The infiltrators opened fire while trying to go back to Pakistan,” the spokesman said.
“In the ensuring firefight, Sepoy Gursewak Singh of 22 Sikh Regiment, aged 23, suffered gunshot wounds and succumbed to his injuries while being evacuated,” the officer said.
“The martyr is survived by his father Balvinder Singh. He belongs to village Warana, Tarn Taran, Amritsar, Punjab.”
The Pakistan Army resorted to unprovoked firing and shelling in Krishna Ghati sector and Mendhar sub-sector of the LoC on Sunday, the spokesman said.
The LoC divides Jammu and Kashmir between India and Pakistan.
At least four places came under indiscriminate shelling and firing from the Pakistan Army which started at 8.40 a.m. Both civil and defence facilities were targeted, a police official said here.
“The Indian Army has effectively retaliated using same calibre weapons. Shelling and firing exchanges are still on,” he said.
Sunday’s violation on the border came after a lull of two days on the LoC and the International Border.
Violations of the 2003 ceasefire agreement by Pakistan have mounted since the Indian Army carried out surgical strikes against terrorist launch pads across the LoC in Pakistani territory in September.
