"During the night, BSF troopers at Khora (Samba) border outpost fired three to four rounds of automatic gunfire after noticing suspicious movements near their post," a police officer said.

"There was no retaliation," he added.

Such firing is done by the BSF and the Army guarding the International Border and the Line of Control (LoC) in the state to foil infiltration attempts by militants.

Security forces are on a vigil after the Gurdaspur terror attack in Punjab earlier this week.
