SRINAGAR, India (AP) — Suspected rebels attacked a police station in the Indian portion of Kashmir with hand grenades and automatic weapons Friday, killing one officer and wounding five others, police said.

Panicked shop owners fled as the assault began in Sopore, a town 35 miles (55 kilometers) northwest of Indian Kashmir’s main city of Srinagar, said Sheikh Faisal, a local police officer. At midday Friday police and the attackers were still exchanging gunfire.

“We downed shutters of our shops and started running away as we first heard sounds of explosions followed by gunshots,” said Firdous Ahmed, a shop owner.

Besides the officer killed, three police officers and two civilians have been hospitalized with wounds from the fighting, Faisal told The Associated Press. No rebel group immediately claimed responsibility.

The attack appeared to be the latest in a surge of violence by separatist insurgents fighting against Indian rule in the disputed region, which is divided between Pakistan and India.

On Thursday, a 15-hour gunbattle between government forces and suspected rebels in the region left three combatants dead.

Last week, suspected rebels attacked government forces in Srinagar’s main commercial hub of Lalchowk, triggering a firefight that lasted 22 hours. Two attackers, one police officer and one civilian were killed.

Anti-India sentiment runs deep in the disputed majority Muslim region, where more than a dozen rebel groups have been fighting for Kashmir’s independence from India or its merger with neighboring Pakistan since 1989.

India accuses Pakistan of arming and training Muslim militants. Islamabad denies the charge, saying it only gives moral and diplomatic support to the rebels.

India and Pakistan have fought two wars for control of the region.

More than 68,000 people, most of them civilians, have been killed in the militant uprising and the subsequent Indian crackdown.
