The camp housed troops of the force's 180th battalion at Ladiyar village of Tral, 35 kms from here, a police official said.
A senior CRPF official in Delhi said the grenade exploded in the area where the troops had gathered for a meal, causing splinter injures to 10 of them. They were rushed to the 92 base hospital, he said.
The area around the camp was cordoned off to nab the unidentified militants, the police official said.
Two CRPF troopers were injured in a grenade attack by militants on their camp in Tral town yesterday. A sub- inspector of the force and three policemen were injured in a grenade attack on a security picket at Saraf Kadal in downtown Srinagar on Sunday.
No militant outfit has so far claimed responsibility for the grenade attacks.
"We have told all our units deployed in Jammu and Kashmir to remained extra vigilant against such attacks and continue to launch operations against militants," the CRPF official said.
