More than 80 people have been killed by Myanmar security forces in a crackdown on protests in the city of Bago, activists said.
The military has reportedly robbed the bodies of those killed, and the actual number of deaths may not be accurately determined.
Witnesses told local media that soldiers used heavy weapons and shot anything that moved.
More than 600 people have been killed since the military coup last month.
The military has relied on increasing the level of violence to maintain control of power.
A recent killing in Bago, near the major cities of Yangon, was reported to have occurred on Friday, but it took a full day to emerge as many residents were forced to flee to nearby villages.
The Assistance Association for Political Prisoners (AAPP), a surveillance group, said: The actual number of deaths could have been much higher..
A Myanmar Now news agency said protester Ye Hut said, “It’s like a genocide. They’re aiming for every shadow.”
Massive protests have taken place throughout Myanmar, also known as Burma, since the military seized control of Southeast Asian nations on February 1 and declared a state of emergency for a year.
The military alleges that during the general election at the end of last year, there was widespread fraud that brought elected leader Aung San Suu Kyi and her National League for Democracy (NLD) party back into power. The Election Commission has rejected this.
With the expulsion of parliamentarians on Friday, the UN Ambassador to Myanmar called on members of the UN Security Council to take action against the military, including extending sanctions and imposing arms embargoes and no-fly zones.
The UN conference also warned that Myanmar is “on the verge of failed state failure.”
Richard Horsey, senior adviser to the International Crisis Group, said military action created a situation that could make the country ungovernable.
Myanmar, also known as Burma, became independent of the United Kingdom in 1948. Much of its modern history was under the military junta.
Regulations began to be relaxed after 2010, free elections were held in 2015, and the following year a government was established led by veteran opposition leader Aung San Suu Kyi.
In 2017, Myanmar troops responded to a deadly crackdown on police attacks by Rohingya militants, driving more than 500,000 Rohingya Muslims across the border to Bangladesh. The United Nations later called it “an example of an ethnic cleansing textbook.”
