The BSF troops responded with equal caliber weapons to Pakistan's firing which resulted in intermittent exchanges of fire, which stopped around 0630 hours on Monday, the officer said.
An elderly villager identified as Attar Singh of Treva hamlet was injured in the mortar shelling, he said.
There were reports that Pakistani Rangers also fired 82-mm mortars on BoPs and some civilian areas in Arnia and R S Pura.
Most of the borderline in R S Pura and Arnia was shelled by the Pakistani Rangers throughout the night, making it the biggest ceasefire violation this year.
The cross-border firing comes ahead of the August 25 Foreign Secretary talks between India and Pakistan.
This is the 11th ceasefire violation by Pakistani troops along LoC and IB in Jammu region during the past 10 days and the 12th in August this year.
