Pakistan opened fire along the LoC in Poonch on Saturday night in the first ceasefire violation in six months.
An Army spokesperson said Pakistan troops started firing heavily on Saturday night which continued until Sunday early morning. Indian troops retaliated in equal measure.
The firing resumed after Pakistan suspended talks between the two nations last week. There have been no instances of firing in the Rajouri-Poonch areas after brigadier level talks between the two armies last October.
The talks were held to diffuse tension along the LoC after six people had died in Pakistan firing last August.
