The slain NSCN (KK) cadre.

An NSCN (KK) cadre was killed when rival factions of the NSCN engaged in a fierce gun battle in a jungle near Chatung village in Longding district of Arunachal Pradesh.

NSCN (KK) rebel Jomie Konyak was killed reportedly by suspected NSCN (I-M) militants on Sunday during an inter-factional clash (IFC), security officials said.

Konyak hailed from Mon district of Nagaland and according to security sources he was operating under self-styled sergeant major Wanglem Wangsu.

Sources said that the rivalry between the two factions was going on for quite some time primarily due to extortion-related activities.

A huge contingent of security forces had moved into the area and launched a massive combing operation to flush out the militants, said a security official.
