Itanagar, June 9 (IANS): Two suspected cadres of Naga militant outfit NSCN-K were killed when an explosive device blew up accidentally at a remote place along the Myanmar border in Arunachal Pradesh on Tuesday, police said.

A third person was injured in the blast which took place at Wakka, just seven kilometers from the border in the newly-created Longding district.

"A group of militants were carrying some improvised explosive devices (IEDs) to be planted against the security forces. One of the IEDs exploded accidentally, killing two cadres instantly," a police official said.

"Their target was perhaps an Assam Rifles post nearby," he said.

The bodies of the two, a live IED and a remote control were found at the spot.

The slain militants were yet to be identified, the official said, adding that villagers told police that the militants forced them at gun-point to carry away the injured insurgent.

On Sunday, the National Socialist Council of Nagaland-Khaplang (NSCN-K) attacked a camp of the Assam Rifles at Lazu in Tirap district. There was no casualty as the paramilitary forces retaliated the attack.

The NSCN-K on June 4 attacked a convoy of the Indian Army in Chandel district of Manipur, killing 18 soldiers and injuring 11 others.
