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 allegedly committed during the nationwide protests. IRNA also said several other Iranian celebrities had ″been summoned by the judiciary body over publishing provocative content.” According to The Associated Press, it did not say how many or provide further details. 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.” In her post, the 38-year-old actress said: ''His name was Mohsen Shekari. 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. Last Week, Iran executed a second prisoner, Majidreza Rahnavard, in connection with the protests. Rahnavard's body was left hanging from a construction crane as a gruesome warning to others. Iranian authorities alleged Rahnavard stabbed two members of its paramilitary force. Both men were executed less than a month after they were charged, underscoring the speed at which Iran now carries out death sentences imposed for alleged crimes related to the demonstrations. Activists say at least a dozen people have been sentenced to death in closed-door hearings.
