An IAF Garud commando was killed and an army soldier was also injured in the encounter.
Six Pakistani terrorists of the Lashkar-e-Tayiba, including the nephew of Mumbai attack mastermind Zaki-ur Rehman Lakhvi, were gunned down in north Kashmir's Bandipora district on Saturday in an encounter in which an Indian Air Force Garud commando was also killed, officials said.
Apart from Lakhvi's nephew, two LeT commanders were also among the terrorists killed by the security forces, Director General of Jammu and Kashmir Police, S P Vaid, said.
Security forces launched a search operation in Chandergeer village in Hajin area of the district after receiving specific intelligence input about the presence of terrorists in the area, a police official said.
The search operation resulted in an encounter when the terrorists hiding there fired on the search party of the security forces, who retaliated.
"Six LeT terrorists have been eliminated in Bandipora encounter," Vaid said.
He said all the six terrorists killed in the encounter were Pakistanis.
One of the terrorists named Owaid is the son of Zakir Rehman Maki and the nephew of Zaki-ur Rehman Lakhvi, he said on Twitter.
Two LeT commanders -- Zargam and Mehmood -- were also eliminated in the operation today, the DGP said, adding that the operation was a "success". Six weapons were also recovered from the encounter site.
Srinagar-based Defence Spokesman Col Rajesh Kalia said an IAF Garud commando was also killed in the operation.
"An IAF Garud commando was killed, while an army soldier was injured," he said.
The Garud Commando Force is the special forces unit of the IAF.
The anti-insurgency operations in Jammu and Kashmir have continued in the wake of violence by Pakistan-based terrorists.
Vaid had recently said around 170 militants were gunned down by the security forces in Jammu and Kashmir this year.
