SRINAGAR, Indian-controlled Kashmir, May 25 (Xinhua) -- Three policemen and a civilian were wounded after militants carried out a grenade attack in restive Indian-controlled Kashmir, police said Friday.

The grenade was hurled on Thursday night towards a police vehicle near bus stand in Jammu city, the winter capital of Indian-controlled Kashmir.

"Last night militants hurled a grenade towards a police vehicle near bus stand here, which exploded with a bang resulting in wounding three policemen and a civilian," a police officer posted in the city said. "The wounded persons were immediately rushed to hospital."

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

So far, no militant outfit has claimed responsibility for the attack.

Indian government has announced a conditional halt in its ongoing military operations during the Muslim holy month of Ramadan in the region.

A guerilla war is going on between militants and Indian troopers stationed in the region since 1989. However, of late Indian policemen too have been trained to fight them.
