The Myanmar Air Force's Yak-130 and MiG-29 jets dropped nine bombs in the attack, although the full extent of damage and casualties in Myanmar remains unknown. In Thailand, a bomb fell near Mae Wan in Mae Sam Laep, causing panic among locals who scrambled for safety.

Thai forces from the 36th Ranger Regiment, based at a Mae Sam Laep checkpoint, worked with local authorities to evacuate residents to Huai Kong Kaad village. Previously, intensified conflict in Myanmar led to airstrikes on KNU areas across from Tha Ta Fang in Mae Sariang district, prompting injured Karen civilians to seek treatment in Thailand.
