At the beginning of June 2012, Tatmadaw Light Infantry Battalion (LIB) #1, under Light Infantry Division (LID) #66 and Commander Win Boh Shein, replaced LIB #5 stationed at Th'Ay Hta camp in Tantabin Township, Toungoo District. On June 23rd, Tatmadaw LID #66 soldiers sent 50,000 sacks of rice to the Kler La area, and demanded Kler La villagers in possession of trucks to transport the rice sacks to front line camps for them.
On the same day, at approximately 10:00 am, soldiers from LIB #1 fired at four villagers crossing the Toungoo - Mawchi vehicle road in a forested area near Wa Baw Day village. Two of the villagers were from D---village, while the other two were from H--- village.
According to the community member based in the area who provided this information, these four villagers were travelling back from Klay Soh Kee in order to buy rice and transport it back to their homes. When they saw the Tatmadaw soldiers, they dropped their rice and fled. None of the four villagers were injured at this time.
The vehicle road runs through mountainous terrain and, as villagers travel back from Klay Soh Kee village carrying rice and other staples, they have to travel along a steep path to cross the road at Wa Baw Day. The place where the villagers were fired at is heavily-forested and approximately two hours on foot from Htee Hsar Per village.
After fleeing the Tatmadaw soldiers fire, the four villagers left their rice sacks on the ground for the whole day during which time there was heavy rainfall. On the following day, June 24th, when the villagers went back to retrieve their rice sacks, they found that the rice had gotten wet and was not usable anymore.
According to the community member who described this incident, the place where the LIB #1 soldiers fired at the villagers is where villagers normally cross back and forth to transport goods to their villages, and it is near to the Tatmadaw camp at Wa Baw Day which has been abandoned since 2008. The camps at Wa Baw Day, and nearby Wa Soh, were both abandoned in 2008 and Tatmadaw soldiers had not come to the Wa Baw Day area or used this portion of the vehicle roadsince then, which is why the villagers were accustomed to using the path to cross the road at this point. Th' Ay Hta camp, where LIB #5 was previously and LIB #1 are currently based, is located southwest of the abandoned camps at Wa Baw Day and Wa Soh.
According to another community member, the ceasefire agreement between the Tatmadaw and the Karen National Liberation Army (KNLA) limits soldiers from patrolling no further than 150 yards from vehicle roads in areas under their respective control. The Tatmadaw camp at Wa Baw Day has been abandoned for approximately four years, and the area had been regularly used by villagers as a necessary route to transport rice to their villages.
Villagers in this area have experienced decades of armed conflict, attacks against villages, and the arbitrary arrest and summary execution of villagers encountered by patrols. Many are accustomed to fleeing and seeking to avoid Tatmadaw patrols as a means of protecting themselves from abuse. Underscoring the risks civilians in areas of long-standing conflict continue to face even during the current ceasefire as they attempt to support their livelihoods, Tatmadaw soldiers did not make any attempt to verify whether the villagers who fled from them were legitimate military targets before firing.
In the days immediately after this incident, increased military activity was described by the community member in the area. On June 24th, a Tatmadaw helicopter surveyed the area around Pee Muh Hkoh in Than Daung Township, and, on June 27th, KNLA soldiers, in groups of five or six, patrolled around the Naw Soh area. While patrolling, they encountered some Tatmadaw soldiers and fighting broke out at that time. 
Currently, there are seven Tatmadaw units active in both Than Daung and Tantabin townships in Toungoo District. They are: IBs #4, #11 and #80, and LIBs #1, #5, #10, and #108. These seven battalions have been based in Toungoo District since January 2012. In July 2012, the units themselves did not change but they rotated some of the camp locations of where they were based.
