At least four Indian soldiers were killed after Pakistani forces fired across the de facto border in the disputed region of Kashmir.

The Indian Army said in a statement on Saturday that Pakistani forces fired on Indian posts in the Rajouri sector, calling it an "unprovoked cease-fire violation."

The statement said that the dead included an army officer.

There was no immediate reaction from Pakistan.

Following the incident, heavy cross-border firing and shelling was reported at several locations along the border.

Pakistani and Indian troops routinely clash along the Line of Control, the de facto border that divides Kashmir between India and Pakistan.
