Myanmar's civil aviation authority said all passenger flights in the country have been suspended.
The US Embassy in Myanmar also reported this information on their Facebook page.
All roads leading to the international airport in Yangon, the country's largest city, were closed on Monday, the US embassy said.
News reports indicate that all airports in Myanmar are closed. In addition, the US Embassy has issued a 'security alert', saying it is aware of the detention of Myanmar's leader Aung San Suu Kyi as well as the suspension of internet services in several cities, including Yangon.
They also said that there is a possibility of political unrest in Burma and we will monitor the situation.
Myanmar's military, which has taken control of the country, said on Monday that the country will hold new elections after a year-long state of emergency and hand power back to a new government.
The president's office declared a state of emergency in Myanmar after State Councilor Aung San Suu Kyi, the country's President U Win Myint and other senior officials were detained by the military.
The country's military said the Union Election Commission would be reformed during the state of emergency and the parliamentary elections held in November last year would be reviewed.
The military demanded the postponement of the new parliamentary session, saying there had been massive vote fraud in Myanmar's general election on November 8, 2020.
However, last week, the Union Election Commission rejected this complaint of the army.
