Iranian director Jafar Panahi, the winner of this year's Cannes Palme d'Or, has been sentenced in absentia to one year in prison, according to the ISNA news agency.
A Tehran revolutionary court also imposed a two-year travel ban, ISNA cited his lawyer as saying.
Panahi, 65, won the top prize at the Cannes Film Festival in May for It Was Just an Accident, a film reflecting his experiences in prison and his encounters with state repression.
The film has been selected as France's submission for the 2026 Academy Awards in the Best International Feature Film category. Panahi has previously won top prizes at the Venice Film Festival and the Berlin International Film Festival.
His lawyer, Mostafa Nili, told ISNA the director has also been barred from membership in political or social groups and said steps would be taken to appeal the ruling.
Panahi is on a tour of the United States visiting Los Angeles, New York and Telluride to promote his Oscar-hopeful movie.
Panahi was imprisoned in Iran from July 2022 to February 2023 and has long faced restrictions on working and travelling. It Was Just an Accident, shot in secret, is inspired by his time behind bars and incorporates conversations with fellow detainees.
Iran's film and cultural sectors have been subject to tight state oversight since the 1979 Islamic Revolution. Filmmakers are required to obtain official permits for shooting and screening work.
However, Iran's vibrant arts and film community has long been a place for subtle - and at times overt - criticism of the system.
