The terrorists reportedly crossed the Line of Control from Pakistan and boarded the bus at Vijaypur. When the bus neared Kaluchak, they shot the driver and the conductor and opened fire on the passengers. On hearing the shots in the bus, the Indian army soldiers fired in their direction. The terrorists, who were dressed in Indian army fatigues, returned fire and attempted to escape to the Army's family quarters, located on the main road. They also threw grenades on some vehicles parked in the vicinity. Upon entering the family quarters, they again fired on Army family members present in the premises. The terrorists were eventually cordoned off and killed by 10 am.
