During an encounter on November 8 in Jammu and Kashmir’s Kupwara district, three Army men and a BSF jawan were killed in the line of duty after terrorists attempted to infiltrate the Line of Control (LoC). Three militants were also gunned down by the security forces in the anti-terror operation, which broke out around 1 am on Sunday. However, two of the injured soldiers have been evacuated. Pakistan is desperately attempting to push in terrorists before the winter sets in, said officials.
