Two Border Security Force (BSF) soldiers were seriously injured in firing from the Pakistani side of the International Border and Line of Control near here Monday night, officials said.
A BSF official said Pakistani troops fired heavily at Pansar post in Hiranagar sector on the International Border, about 90 km from here.
He said two soldiers who were patrolling the area were injured in the firing.
"The fire was heavy and appeared to target the patrol party," the official said.
The BSF soldiers retaliated to the firing, leading to heavy exchange of fire between the two sides which continued late into the night.
The injured were evacuated from the site of firing and rushed to the District Hospital in Samba.
The soldiers are Bhuvneet Singh, a native of Gurdaspur in Punjab, and Hari Mohan, a native of Kanpur in Uttar Pradesh. Their condition is stated to be critical.
In another incident, the Pakistan Army resorted to heavy firing in Kirni sector in Poonch on the Line of Control, about 240 km from here.
"The firing appeared an attempt to give cover to infiltrators," said an army spokesperson.
The Indian side retaliated in both the cases.
The incident comes a day after Pakistani Rangers fired at a post in the Arnia sector on the International Border near Jammu.
Security and vigil on the international border and LoC has been tightened ahead of Independence Day when militants usually make attempts to strike.
