The attack came a week after eight CRPF jawans were killed and 20 others injured on Saturday in a militant ambush on a convoy in Pampore town in Pulwama district, the highest single-incident casualty in three years in the state.
A police official said the CRPF personnel retaliated the firing by the terrorists at the camp in Litter, about 35 km from Srinagar.
Four jawans were injured, the official said.
