After NSCN-IM signed the historic Naga Peace Accord with the Government of India, ending the five-decade-long dispute, reports suggest that militant group NSCN-K is planning to disrupt peace in the North-eastern region.

NSCN-K leder S S Khaplang, who is in Myanmar, is planning something nasty, intelligence reports said. Around 20 militants of the group are active in the nation, reports said.

As reported, Khaplang was medically unwell but has recovered. He has been planning a terror attack, as a mark of opposition to the recently signed Naga Peace Accord. As many as 50 militants of the outfit were killed in June by Indian security forces and intelligence reports claim that the outfit will also try to avenge the encounter.

"Thankfully, they have not been able to mount an attack. Security forces in Manipur and Nagaland have been on a high alert since the June operation. Khaplang faction will try to sabotage any attempt at peace to send a message," Times of India quoted an intelligence officer.

It is being suspected that along with Myanmar, China has also been extending support to Khaplang's NSCN-K. North-eastern States including Assam, Manipur, Nagaland and Arunachal Pradesh are under threat.

The Naga Peace Accord was signed in the presence of NSCN-IM leaders Isak Chishi Swu and Thuingaleng Muivah. The details of the agreement are yet to be disclosed.
