The Treasury Department froze the assets of 10 current and retired top-ranking military leaders in Myanmar after a coup earlier this month that toppled the government of Aung San Suu Kyi.
A week after Myanmar's military seized power, it imposed restrictions in major cities to quell growing protests, as the coup's leader promised a new election in his first televised address.
Calling for the release of detained de factor leader Aung San Suu Kyi and chanting anti-military slogans, protesters amassed across the country Sunday demanding an end to the military takeover.
Days after a coup and the detention of Aung San Suu Kyi and other elected leaders, the country's military is moving to strangle free speech by shutting down access to social media sites.

The military detained Suu Kyi and members of her political party early Monday, hours before it declared a transfer of power and a one-year state of emergency in the Southeast Asian country.
Aung San Suu Kyi and her National League for Democracy appear set to remain in power after Sunday's general election, which is largely seen as a referendum on Suu Kyi's first term.

In a unanimous decision, a 17-judge panel said Myanmar must take steps to protect the Muslim minority Rohingya, who "remain extremely vulnerable" after a brutal 2017 crackdown by the military.
