Suspected extremists ambushed a convoy of 40 Assam Rifles in Nagaland’s Mon district on Saturday, killing two personnel of the paramilitary force and injuring three others. Officials said the ambush took place at Thainyak between Ukha and Tobu in the district bordering Myanmar. “There was an exchange of fire after the ambush at 1 p.m. Two of our men died, and the injured were taken to a hospital,” an Assam Rifles spokesperson said. The gunfight lasted an hour, but the security agencies could not confirm if any extremist was killed. No organisation has claimed responsibility, but the needle of suspicion is on the Khaplang faction of the National Socialist Council of Nagaland that operates from its base in Myanmar, but has been under pressure from the armed forces of both countries. Other extremist groups such as the United Liberation Front of Assam and some Manipur outfits have been fighting alongside the NSCN(K) under an umbrella organisation. Saturday’s attack happened at the same place where NSCN(K) had attacked and killed nine Assam Rifles personnel in 2015.
