One of the three terrorists who fired at an ambulance that was part of an army convoy moving near the LoC on Monday morning was killed by evening in the operation that also witnessed action by special forces and NSG commandos and the use of BMP-II infantry combat vehicles

The other two terrorists were killed on Tuesday in a span of two hours after the joint teams of the army and the police launched the final assault near the Assan temple in Jogwan village in the Battal-Khour area, the officials said

They said the encounter has ended but the operation is on to retrieve the bodies of the slain terrorists who are believed to have infiltrated from across the border on Sunday night before appearing outside a temple and targeting the army convoy

"After a night-long lull, the security forces pushed for a final assault against the holed-up terrorists at around 7 am, leading to a fresh gunfight," an official said

A couple of deafening explosions followed by intense firing continued for over an hour before the second terrorist was killed, the officials said

Intermittent exchange of fire continued for another hour before the third trapped ultra was eliminated, the officials added

A four-year-old valiant Army dog, Phantom, died after being hit by a bullet during the operation

In a first, the Army has also pressed its four BMP-II infantry combat vehicles for surveillance and strengthening the cordon around the attack site, while helicopters and drones were also deployed to locate the hiding terrorists

The latest encounter in the Jammu region comes amid a surge in terrorist activities in Kashmir where seven attacks have occurred in the past two weeks, resulting in 13 fatalities, including two soldiers
