The sound of pots and pans rang out in protest in Myanmar's biggest city Tuesday night clangs and honking car horns marked the first widespread protest against the military's coup this week.
Some shouted "evil be gone", a traditional gesture to drive out evil or bad karma.
The military has refused to accept the election victory of the government of Aung San Suu Kyi and her National League for Democracy party which won by a landslide last November.
The army has imposed a state of emergency for a year after they swiftly seized power Monday, detaining Suu Kyi and others, claiming election fraud.
Late Tuesday, a senior party official said he learned that Suu Kyi was under house arrest in the capital Naypyidaw and was quote "in good health", but would not be moved.
An earlier post said she was at her home, but Reuters was unable to confirm.
And on Wednesday, 70 hospitals, and medical departments across Myanmar stopped work to protest against the coup, according to a statement posted on Facebook.
