The search operation was being conducted at Paralong, Charong, Moltuh and some other areas to track down the insurgents who had launched attack on the army jawans, the sources said.
They, however, could not say whether anyone was detained or arrested in connection with yesterday's incident, saying that the search operation was being conducted by the army and Assam Rifles personnel.
The army or Assam Rifles could not be contacted.
Army and civilian authorities suspect the involvement of Manipur rebel outfit Peoples Liberation Army (PLA) and Kanglei Yawol Kanna Lup (KYKL), a Meitei revolutionary organisation, which used landmines, rocket-propelled grenades and automatic weapons in the ambush.
The area where army personnel were ambushed is about 15-20 kms from India-Myanmar border.
