SRINAGAR, Indian-controlled Kashmir, June 22 (Xinhua) -- At least five paramilitary troopers and four policemen were wounded Friday after militants carried out a grenade attack in restive Indian-controlled Kashmir, police said.

The grenade was hurled at a contingent of Central Reserve Police Force (CRPF) in Tral town of Pulwama district, about 46 km south of Srinagar city, the summer capital of Indian-controlled Kashmir.

Police said the grenade exploded with a bang, leaving CRPF and police personnel wounded.

"Five CRPF personnel and four policemen were wounded today after militants lobbed a grenade towards them in Tral," a police official posted in town told Xinhua over telephone. "All of them have suffered splinter wounds in the attack and have been hospitalized."

Soon after the attack, police contingents rushed to the spot and launched a manhunt to nab the attackers.

A local news gathering agency said the region's indigenous militant outfit - Hizbul Mujahideen claimed responsibility for the attack.

Earlier in the day, four militants, a policeman and a civilian were killed in a gunfight in Anantnag district.

A guerrilla war is going on between militants and Indian troopers stationed in the region since 1989.
