The Pakistani troops opened fire with small weapons on the Khour border outpost along the Line of Control (LoC) of Jammu district late on Wednesday night.
The firing comes on the fifth anniversary of the formal ceasefire between India and Pakistan along the International Border (IB), Line of Control and the Actual Ground Position Line in Jammu and Kashmir.
Pakistan and India had singed the ceasefire agreement exactly five years on November 26, 2003.
A havaldar, Surya Pratap Singh, of 9 Raj Rifles, was injured in the firing and was later shifted to the army hospital in Udhampur.
However, Indian troops guarding the Line of Control have not returned fire.
This was the 36th ceasefire violation by Pakistan and the second in the month of November. Earlier, two BSF personnel had been injured when in firing from the Pakistani side on the outposts of Durga in Jammu on November 4.
