SRINAGAR: - Suspected militants stormed a paramilitary base in Indian Occupied Kashmir (IOK) early today, police said, leaving one soldier and three attackers dead.

Three paramilitary troopers were also injured when at least three militants hurled grenades and fired automatic weapons at the Border Security Force (BSF) base near Srinagar's airport before dawn.

"Two militants have been killed so far, one is still there. And one BSF soldier was killed in the initial assault," inspector general of police, Muneer Ahmed Khan told AFP.

Authorities suspended operations at the city's airport, while at least one in-bound flight from New Delhi was cancelled, officials said.

"We will resume normal airport operations soon," Manzoor Dalal, a police official at the airport, told AFP.

"Outstation bound passengers (are) allowed towards Srinagar airport," a short police statement added.

Kashmir has been divided between India and Pakistan since the end of British colonial rule in 1947 but both claim the territory in full.

For decades rebel groups have fought roughly 500,000 Indian soldiers deployed in the territory, demanding independence or a merger of the former Himalayan kingdom with Pakistan.

Tuesday's attack came a day after Indian soldiers killed five suspected rebels near the heavily militarised Line of Control (LoC) that divides the territory with Pakistan.

In August militants attacked a police base in souther Pulwama town killing eight security personnel during a day-long gun battle.

Two children were killed Monday during an exchange of gunfire between Indian and Pakistani troops, Indian authorities said.

Last month, Pakistan said a five-year-old girl had been killed when she was hit by a bullet fired from the Indian side.

New Delhi has said Pakistan initiates cross-border firing to help anti-India rebels cross into Indian-administered Kashmir to launch attacks.

However, Islamabad says it provides only diplomatic support to the Kashmiri campaign for self-determination.
