New Delhi: Two army soldiers were killed and nine other jawans injured when NSCN-K militants ambushed their convoy in defence spokesman said.
The militants opened fire at an Assam Rifles convoy at Nginu village in Tirap district near the India-Myanmar border.
The attack took place around 2 pm.
"Soldiers belonging to the 16 Assam Rifles were returning from a patrol when the heavily armed militants fired at them. While two of them including a JCO (junior commissioner officer) died, eight others were injured.
"The condition of two of them are stated to be serious," IANS quoted a defence spokesman as saying.
"We believe it to be the handiwork of anti-talk faction, Nationalist Socialist Council of Nagaland-Khaplang militants who have some presence in Tirap district.
According to ANI, a massive search operation was underway after the attack.
This is the second major attack on the security forces in less than a month in the northeast.
Last month, three soldiers were killed and four others were injured in Assam's Tinsukia district in a similar attack by the ultras.
An army convoy was ambushed by militants, suspected to be a breakaway faction of ULFA, when they were returning from an operation in the district.
The militants triggered an IED blast before raining bullets on the convoy.
