Burmese air strikes left dozens injured as resistance forces clashed with the Myanmar junta near the Thai border.

The Myanmar Air Force reportedly carried out retaliatory bombings on the Karenni Army as guerrilla troops besieged the 134th Infantry Regiment stronghold in Karenni State on June 26.

A Khun Yuam Police Station spokesman said at least 38 people caught in the clash were being treated at the Khun Yuam Hospital in Mae Hong Son.

Footage shows the wounded individuals being wheeled into the hospital's emergency area.

A Karenni Army spokesman said they had difficulties transporting the casualties to Thailand amid the relentless air strikes.

Thai authorities deployed a mini Medical Emergency Response Team with air support to transport the injured to the Nakornping Hospital.

Dr Prasan Piamanan, an Emergency Medicine doctor from Nakornping Hospital, said they will assist Khun Yuam Hospital for three days until the border clashes stop. He added the hospital bills will be shouldered by the International Committee of the Red Cross.

Myanmar has fallen into civil war following the removal of democratically elected leader Aung San Suu Kyi, a Nobel Peace Prize winner, with a military coup in 2021.

Soldiers responded with barbaric force on protesting civilians leading to widespread condemnation and financial sanctions. Rebel groups and civilian militias around the country have since been locked in a series of ongoing clashes with the ruling military.

Aung San Suu Kyi has since been jailed for 33 years on politically motivated charges and is likely to die behind bars unless the army is toppled - a tragic end the politician hailed by Barack Obama as an 'inspirational icon of democracy'.
