The US has imposed sanctions on four Myanmar military and police commanders and two army units for involvement in what it called "ethnic cleansing" and other human rights abuses against the country's Rohingya Muslims.
The sanctions, announced on Friday by the US treasury department, marked the toughest US action so far in response to Myanmar's crackdown on the Rohingya minority.
The crackdown started last year and has driven more than 700,000 people into neighbouring Bangladesh and left thousands of dead behind.
But the Trump administration did not target the highest levels of the Myanmar military and also stopped short of calling the anti-Rohingya campaign crimes against humanity or genocide.
"Burmese security forces have engaged in violent campaigns against ethnic minority communities across Burma, including ethnic cleansing, massacres, sexual assault, extrajudicial killings, and other serious human rights abuses," said treasury under secretary for terrorism and financial intelligence, Sigal Mandelker.
"Treasury is sanctioning units and leaders overseeing this horrific behaviour as part of a broader US government strategy to hold accountable those responsible for such wide-scale human suffering," Mandelker said.
The sanctions targeted military commanders Aung Kyaw Zaw, Khin Maung Soe, Khin Hlaing, and border police commander Thura San Lwin, in addition to the 33rd and 99th Light Infantry Divisions, the Treasury said.
A Reuters special report in June gave a comprehensive account of the roles played by the two infantry divisions in the offensive against the Rohingya.
Myanmar's military has denied accusations of ethnic cleansing and says its actions were part of a fight against terrorism.
