"On September 10 at 8:00 am, a group of about 60 Burma Army troops from LIB 325 based in Mong Yai and the local Nam Pawng pro-government militia, were on patrol north of Wan Loi Yoi, Pa Karng tract, Mong Yai township, when they encountered a land mine blast. They then started indiscriminately shelling and shooting. When they heard the shelling and shooting, all the residents of Wan Loi Yoi ? about 300 people from 50 houses - fled their homes in three cars and Chinese trucks. About 100 villagers fled to Wan Nam Poak (a Shan village with over 200 inhabitants) in Pa Karng village tract, taking refuge there for one day, and about 200 villagers fled into the jungle and sheltered in farm tents. Wan Loi Yoi is situated about 20 miles from Mong Yai town, in the southwest of Mong Yai township, Lashio district, northern Shan State..."
