The suspected militants started indiscriminate firing after noticing the patrol party, and the security personnel retaliated, the defence spokesperson said.
During the firing, the intruders fled towards the Myanmar side, he said.
The patrolling was launched following specific information about the movement of some individuals in Ponghcau circle along the India-Myanmar border, the defence official said.
The area was thoroughly searched by the security forces, but the intruders managed to cross the border, taking advantage of the dense forest, he added. PTI CORR UPL BDC
