At least two NSCN-K militants were killed along the India-Myanmar border in Nagaland during an operation by the Indian Army on Thursday.The army's Special Forces launched the operation in Phek district's Awankhu area late Wednesday after getting reports of the movement of National Socialist Council of Nagaland-Khaplang militants in the area, an army spokesman said."During the operation, the security forces came face to face with a group of armed NSCN-K cadres. They started firing on our forces leading to retaliation from our side. The firing continued for about one hour," he said.Later, two bodies were recovered from the spot, the official said, adding that two AK series rifles and a large quantity of ammunition were also seized.The security forces have intensified their operation against the NSCN-K, which abrogated the ceasefire agreement with the central government in March and attacked an army convoy in Manipur in June killing 18 soldiers and injuring 11 others.
