The militants, however, managed to escape after the gunbattle and security forces were making efforts to track them down, they added.
Security forces cordoned off the Mir Mohalla village in the Hajin area of the district this morning following intelligence inputs about the presence of militants, a police official said.
As the forces were conducting searches, the militants opened fire triggering a gun battle, the official said.
Constable Zahir Abbas of the J&K police was killed while an Army soldier sustained minor injuries in the gun-battle, he said.
An Army official said that search operations had been expanded to nearby areas to track down the militants.
