Three militants and a policeman were killed on Friday in an encounter in a forest area in Ganderbal district of Jammu and Kashmir, defence sources said.
The gunbattle broke out on Thursday at Chak-Akhal, 45 kms from Srinagar, when security forces launched a search operation to track down hiding militants.
They said three militants have been killed in the encounter while a policeman also laid down his life.
Three other security personnel have been injured since last evening in the operation which was still on, the sources said.
The identity and group affiliation of the slain militant could not be ascertained immediately, they added.
