Indian troops targeted a vehicle of the Pakistan Army moving along the Neelum River at Athmuqam on Sunday. "The vehicle fell into the river and four soldiers embraced martyrdom in the Line of Control (LoC) ceasefire violation,” said the Inter-Services Public Relations (ISPR).
The body of one martyred soldier has been recovered while search for the other three is underway.
The attack was similar to an earlier assault on a civilian bus in the same area last year, according to the army's media wing.
The ISPR said that Pakistani forces had responded to the ceasefire violation.
Earlier this year in June, during a National Assembly's Standing Committee on Kashmir Affairs meeting, director general of the Disaster Management Authority said that unprovoked firing by Indian forces across the LoC had taken 832 lives while 3,000 people had been injured and 3,300 houses had been damaged.
