Many of the villages targeted are controlled by the Karen National Union (KNU), an ethnic armed group that holds large swathes of territory in the borderlands.
A 5-year-old boy died in a bombing on Sunday, and a 12-year-old girl was hit in the face by bomb shrapnel, according to relief organization Free Burma Rangers (FBR). The girl had come to Day Bu Noh village to attend school, the group said.
A high school in Dwe Lo Township was destroyed in an airstrike on Monday, but no casualties were reported as the students were in hiding, FBR said. Then on Tuesday, six people were killed and 11 injured by airstrikes near Hsaw Hti township.
In a statement Tuesday, the KNU condemned the Myanmar military’s bombing campaign. “Villagers, including underage children, have been killed by airstrikes,” the KNU statement said. “Many are injured.”
CNN has not been able to independently verify these reports.
