Iranian authorities have arrested actress Taraneh Alidoosti, the star of the 2016 Oscar-Award-winning film “The Salesman,” on charges of spreading falsehoods after she posted on Instagram that the country’s recent execution of Mohsen Shekari was a “disgrace to humanity.” Iranian state media IRNA said Alidoosti was detained because she failed to provide “documentation in line with her claims,” one week after she expressed solidarity in an Instagram post with a man executed in recent anti-government protests, multiple outlets reported Saturday.
