It was a major success for the security forces as Najar was wanted for his alleged involvement in more than 50 killings, including that of policemen in Hygam area of Sopore in the past 17 years.
Baramulla Senior Superintendent of Police (SSP) Imtiyaz Hussain said, "Najar was killed as security forces foiled an infiltration bid in Lachipora area near the LoC this morning."
"He was returning to Kashmir to take over the command of Hizbul Mujahideen in the wake of elimination of top commanders of the outfit by security forces," he told Press Trust of India.
"Najar started his career as a terrorist with the killing of Hizb commander Abdul Majid Dar in 2003," he said.
The officer said Najar was called to the base camp in Pakistan-occupied Kashmir by his handlers in 2015 after he fell out with the Hizbul leadership.
"He was now tasked with reviving the outfit in Kashmir in the wake of elimination of top militants," he said.
