Britons in Myanmar have been warned against all but essential travel across the Asian country following a military coup.
A state of emergency has been called after the army assumed control with de-factor leader Aung San Suu Kyi and other politicians detained.
All international flights have been suspended until February 28 at the earliest and land borders are shut.
The UK government condemned the state of emergency imposed by the Myanmar military, and the detention of members of the civilian government and civil society, including state counsellor Aung San Suu Kyi and president Win Myint.
“The UK calls on the military to respect the rule of law and human rights, and release those unlawfully detained,” a government statement added
“We need to see the peaceful reconvening of the National Assembly, respecting the results of the November 2020 general election and the expressed wishes of the people of Myanmar.”
The Foreign Office said: “There are reports that figures in the civilian government and civil society have been detained by the military.
“The British Embassy is following the situation carefully and will continue to update the travel advice.
“There may be disruptions to internet, phone networks and ATMs.
“You are advised to stay home and stay safe.”
The FCDO added: “Political tension and unrest could happen at short notice.
“You should avoid all demonstrations and large gatherings. Do not take photographs or videos of the police, demonstrations, military installations or military personnel.”
British explorer Levison Wood tweeted: “Military has taken over in Burma again in a coup. Very sad after the progress made in last few years.”
Myanmar, also known as Burma, was ruled by the military until democratic reforms began in 2011.
