The camp housed troops of the 180th battalion of CRPF at Ladiyar village of Tral, 35 kms from here, a police official said.
He said the grenade exploded inside the camp, causing splinter injuries to nine jawans.
They were taken to a hospital and the area around the camp was cordoned off to nab the unidentified militants, the official said.
This was the second grenade attack in Tral in two days and third such incident in the valley since Sunday.
No militant outfit has so far claimed responsibility for the grenade attacks.
