This is the best summary I could come up with:

Nov 12 (Reuters) - A Myanmar fighter jet has crashed during clashes between the military and an insurgent group, both sides said, in another setback for a junta facing the biggest challenge to its rule since a coup in 2021.

The jet went down over Kayah State in eastern Myanmar, near the border with Thailand, on Saturday during fighting between the military and the Karenni Nationalities Defence Force (KNDF), which said it shot down the plane.

Junta spokesperson Zaw Min Tun told state-run MRTV the jet crashed due to a technical problem and the pilots had ejected safely and were in contact with the military.

Conflict in Shan State, in the northeast bordering China, has displaced at least 50,000 people, with trade routes cut off and several towns seized since an anti-junta offensive launched last month by three ethnic minority insurgent groups.

Hundreds of foreign workers, many of whom rights activists say are victims of human trafficking, are trapped by the fighting, including citizens of Vietnam and of Thailand.

The KNDF said on its Facebook page it shot down the jet on Saturday using heavy machine guns and its members were searching for the pilots.
