Myanmar's UK ambassador has been locked out of the country's London embassy after calling for the release of detained leader Aung San Suu Kyi.
Kyaw Zwar Minn told Reuters news agency "I have been locked out", having spoken out against the military coup that has led to the deaths of dozens of protesters.
His deputy, Chit Win, has barred him and taken charge of the building on behalf of the military, diplomatic sources told Reuters.
"It's a kind of coup, in the middle of London... you can see that they occupy my building," said the ambassador, adding that he was talking to the UK Foreign Office about the development.
Last month, he had called for the release of Ms Suu Kyi and ousted President Win Myint.
Metropolitan Police said on Wednesday evening that there was a protest outside the embassy and that public order officers were on the scene. No arrests have been made.
At least more 15 protesters are reported to have been shot dead by the military in Myanmar on Wednesday, according to activists and media in the country.
Dozens are also said to have been wounded.
The army ousted Myanmar's elected government on 1 February, claiming there had been voter fraud in last year's election.
The independent election commission said there was no evidence to back that up and many people are now regularly being killed at protests over the power grab.
Senior General Min Aung Hlaing, leader of the coup, claims the pro-democracy demonstrators are trying to "destroy" the country.
