SRINAGAR: A policeman and a civilian were killed Tuesday when suspected rebels opened fire outside a Muslim shrine in India-held Kashmir, police said.

The militants targeted the police officer guarding the shrine of Tujjar Sharif, 55 kilometres northwest of the main city of Srinagar.

"The policeman unfortunately lost his life, and a civilian who was shot during the attack succumbed to his injuries later," deputy inspector general of police for the area, Gharib Das, told AFP.

"It appeared that the policeman on guard was the target, not the shrine." It was not clear if the 70-year-old disabled civilian was shot by the militants or he was hit by a bullet when police returned fire.

The militants fled the area after the attack and the dead police officer's automatic rifle was missing, Das said, adding security forces had launched a hunt for the attackers.

Rebels in recent years have often attacked lone police officers on duty and snatched their service weapons.

Last week a bomb hidden in a steel pot exploded inside the compound of a mosque in the southern Kashmir valley, injuring ten people. No rebel group claimed responsibility for the rare explosion.

Several groups have for decades battled hundreds of thousands of Indian troops deployed in the region, for independence or a merger of the territory with Pakistan.

The conflict has left tens of thousands, mostly civilians, dead.

Kashmir has been divided between India and Pakistan since the end British colonial rule in 1947. Both claim the disputed Himalayan region in its entirety.

The two countries frequently exchange fire across their disputed border in Kashmir. The cross border firings have occured almost daily since the past one week.
