However, the army, CRPF and police retaliated the fire, triggering a brief gunfight during which four foreign militants were killed.
This is published unedited from the PTI feed. Dozens of local youths have joined the rebel ranks since a year ago when the killing by security forces of a popular rebel commander sparked wide-scale anti-India protests that left more than 100 civilians dead and thousands wounded.
"Congratulate 45th battalion of CRPF in particular and entire force of CRPF and J&K police for their alertness and unmatched courage", the Home Minister's Office tweeted. The identity of the militants has not been ascertained yet.
Sources say that terrorists opened fire on the CRPF camp early this morning. "Additional reinforcements have been sent to the area to prevent the situation from going out of control", the officer said.
A police official said the unidentified terrorists were killed while attempting to launch a suicide attack on the 45Bn headquarters CRPF camp in Sumbal.
"Few militants fired on the CRPF camp and the alert security guard retailed the fire".
Four AK rifles, one under-barrel grenade launcher and large quantity ammunition, cans full of patrol were recovered from the slain terrorists.
Singh said the Central Reserve Police Force personnel, in cooperation with men from an adjoining Jammu and Kashmir Police camp, killed all the four terrorists.
A police official told Rising Kashmir: "The authorities banned the mobile internet immediately after protests broke out in the Sumbal area of the district".
