A spokesman for the military did not respond to calls requesting comment on the violence at Depayin in the Sagaing region, about 300 km (200 miles) north of the capital, Naypyidaw.
The state-run Global New Light of Myanmar said "armed terrorists" had ambushed security forces patrolling there, killing one of them and wounding six. It said the attackers retreated after retaliation by the security forces.
Myanmar has been plunged into chaos by the Feb. 1 coup against elected leader Aung San Suu Kyi, with violence flaring in many parts of the country of more than 53 million people.
One resident of Depayin, who did not want to be identified for fear of reprisals, said four military trucks dropped soldiers at the village early on Friday.
