New Delhi: Naga insurgent group National Socialist Council of Nagaland-Khaplang (NSCN-K) has said more than two of its guerrillas were killed in a crackdown by the Myanmarese army in that country.

"Myanmar's army has been targetting our boys since the past two weeks on the pretext of evicting anti-India guerrillas from its soil," senior NSCN-K leader A Z Jami told sources from an undisclosed location.

"Two-three of our boys and some Myanmar armymen have been killed in the heavy exchange of fire in Saigang area," he said, adding the group has asked its cadres to "exercise maximum restraint".

Jami said the action by Myanmar army has come after intense pressure from India and Indian troops are positioning themselves along the international border.

External Affairs Minister Pranab Mukherjee had last visited Myanmar and sought its help in evicting rebels seeking refugee across the border.

The NSCN-K, whose top leader S S Khaplang, is a Zemi Naga from Myanmar, is in ceasefire with the Centre since 2001 but peace talks are yet to start.
