Srinagar, June 25 (IANS): Two separatist guerrillas were killed and five Central Reserve Police Force (CRPF) troopers injured on Saturday in a gunfight after guerrillas ambushed a CRPF convoy on the Srinagar-Jammu national highway in Jammu and Kashmir's Pulwama district, police said.

"A CRPF convoy on way to Srinagar was attacked by militants at Namblabal near Pampore town on the Srinagar-Jammu national highway," a senior police officer told IANS.

"The firing was returning and two militants were killed in the retaliatory action by the CRPF troopers," he said, adding five CRPF troopers were injured, two of them critically.

"All the injured have been shifted to hospital," the officer said.

"Firing exchanges are still going on at the attack site as two militants are still reported to be firing at the security forces," he said, adding reinforcements have been rushed to the area to ensure that the surviving militants don't escape.
