Bombs from four airstrikes hit a shelter for internally displaced persons between 4.15am and 4.39am injuring some residents, according to the press.
The Karenni Army (KA) and Karenni Nationalities Defence Force (KNDF) rushed to the scene to defuse a bomb that failed to explode.
The airstrikes came as the Myanmar army tried to deliver supplies to its troops at a base ambushed by Karenni forces.
