Iranian authorities arrested one of the country’s most famous actresses on charges of spreading falsehoods about nationwide protests that grip the country, state media said Saturday. The report by IRNA said Taraneh Alidoosti, star of the Oscar-winning movie “The Salesman,” was detained a week after she made a post on Instagram expressing solidarity with the first man recently executed for crimes committed during the nationwide protests. According to the report published on the state media’s official Telegram channel, Alidoosti was arrested because she did not provide ’’any documents in line with her claims.″ ''His name was Mohsen Shekari.'' she said in her post. ‘‘Every international organization who is watching this bloodshed and not taking action, is a disgrace to humanity." Shekari was executed Dec. 9 after being charged by an Iranian court with blocking a street in Tehran and attacking a member of the country's security forces with a machete.
