Troops of 56 Rashtriya Rifles noticed some suspicious movement of two to four persons along the LoC in Macchil sector at around 3.00 AM and challenged them, an Army spokesman said here.
The militants, who were trying to sneak into the Valley from Pakistan occupied Kashmir, opened fire on the army positions including on Dingeri Post, which was retaliated.
In the ensuing gunfight, a JCO identified as Arun Kumar was killed while a soldier Solanki Raju was injured.
The ultras left behind two assault rifles and some war-like stores before crossing back into PoK territory, he said.
