TEHRAN (AFP)–Prominent Iranian film director Jafar Panahi was arrested at a cemetery where mourners gathered Thursday to commemorate slain election protesters, a source close to the family said. “Panahi, his wife Tahereh Saeedi and daughter Solmaz were arrested today at Behesht-e Zahra,” the source who declined to be named told AFP. The award-winning director of ‘Offside’ and ‘The Circle,’ Panahi is a vocal critic of Iran hardliners and his movies have been banned for a decade from domestic theatres despite their international success. Several other mourners were also arrested by Iranian riot police who beat the crowds gathered to commemorate protesters killed in post-election violence last month, witnesses said. Mourners were marking the 40th day since the death of Neda Agha-Soltan, a young woman who came to symbolise the protest movement against the re-election of President Mahmoud Ahmadinejad.
