The Military regime forces kicked and beat the passengers in Yangon's Okkalapa Township on Friday.
Eyewitnesses say the security personnel told the passengers to get off the bus and kneel then kicked passengers and drivers.
The incident forces bus to take an alternate route to avoid the security forces. When residents left their house to see what's happening, forces opened fire in residential wards.
“When residents went out to see what happened after they saw buses driving through their wards, security forces came and fired shots at the wards. They swore loudly and viciously as they shot,” said a ward resident, The Irrawaddy reported.
“They got on YBS [Line No.] 64 and kicked the driver. They kicked the male passengers provocatively at gunpoint, telling them to fight back if they were men. And they also pulled the hair of female passengers and slapped them in their faces,” an eyewitness wrote on Facebook.
At least 20 people were killed and dozens were injured during crackdowns on North Okkalappa Township on March 3.
Martial law has been imposed in the region.
