WASHINGTON - The United States announced sanctions on Tuesday against the Myanmar military's Commander-in-Chief Min Aung Hlaing and other leaders it said were responsible for extrajudicial killings of Rohingya Muslims, barring them from entry to the United States.

The steps, which also covered Min Aung Hlaing's deputy, Soe Win, and two other senior commanders and their families, are the strongest the United States has taken in response to massacres of minority Rohingyas in Myanmar, also known as Burma.

It identified the two others as Than Oo and Aung Aung, both brigadier generals.

"We remain concerned that the Burmese government has taken no actions to hold accountable those responsible for human rights violations and abuses, and there are continued reports of the Burmese military committing human rights violations and abuses throughout the country," U.S. Secretary of State Mike Pompeo said in a statement.

Pompeo said a recent disclosure, first reported by Reuters in May, that Min Aung Hlaing ordered the release of soldiers convicted of extrajudicial killings at the village of Inn Din during the ethnic cleansing of Rohingya in 2017 was "one egregious example of the continued and severe lack of accountability for the military and its senior leadership."

"The Commander-in-Chief released these criminals after only months in prison, while the journalists who told the world about the killings in Inn Din were jailed for more than 500 days," Pompeo said.

The Inn Din massacre was uncovered by two Reuters reporters, Wa Lone and Kyaw Soe Oo, who spent more than 16 months behind bars on charges of obtaining state secrets. The two were released in an amnesty on May 6.

The U.S. announcement came on the first day of an international ministerial conference on religious freedom hosted by Pompeo at the State Department that was attended by Rohingya representatives.

"With this announcement, the United States is the first government to publicly take action with respect to the most senior leadership of the Burmese military," said Pompeo, who has been a strong advocate of religious freedom.

"We designated these individuals based on credible information of these commanders’ involvement in gross violations of human rights," he said. -Reuters
