In the first week of September 2025, the military launched a large-scale offensive to regain control of areas held by the joint revolutionary forces of the Karen National Union (KNU) and the People's Defense Force (PDF). These areas include the Myawaddy-Kawkareik Asia Highway, as well as Battalions 355, 356, 357, and their tactical command posts. As a result of the offensive, local residents from the villages of Htee Moo Hta, Noh Poe, Kwin Kalay, and Mae Ka Nel, located near the Thingannyinaung village tract in Myawaddy Township, Karen State, have been forced to flee the conflict.
