Tension continued in Athibung town of Peren district of Nagaland following Thursday's heavy exchange of fire between rival NSCN factions.
State Home Minister Thenucho, in a statement here, said the situation in Athibung was tense but under control.
He informed that two companies of the state police force, including an IRB company, had been deployed in the town.
An Indian Reserve Battalion (IRB) jawan was seriously injured in the cross-firing.
The NSCN(IM) and NSCN(K) had ignored repeated requests by the Assam Rifles (AR) unit deployed near the site of the gunbattle to stop the firing at the civilian area.
Meanwhile, in a statement, the NSCN(IM) 'deputy kilonser' alleged that AR personnel were protecting the NSCN(K) cadres who had raised hundreds of bunkers in and around Athibung town.
He said they had already invited chairman of the cease fire monitoring group.
