Security forces began the violent crackdown on Saturday, after weeks of largely peaceful protests against the 1 February military takeover. Government leaders, including Aung San Suu Kyi, were overthrown and detained.
Social media footage from Sunday showed protesters running away as police charged at them, makeshift roadblocks being erected, and several people being led away covered in blood. The police operation was expanded on Sunday as coup leaders sought to quash a civil disobedience campaign that has shown no sign of ending. US National Security Adviser Jake Sullivan said the Biden administration was preparing "additional actions" against those responsible for the violent crackdown.
