Life magazine says the Iranian photographer who submitted this photo of protests in Tehran is now missing and probably arrested. Here is a gallery of the photographer's work with a note from Life. It's unknown if the photographer is counted among the 24 journalists and bloggers who have been reported arrested, among them Ali Mazroui, the head of the Association of Iranian Journalists, who was grabbed Sunday morning. Stories by the LAT's Borzou Daragahi continue to carry a Tehran dateline. At least 13 people were reported killed Saturday after protesters defied government orders not to assemble. The daughter and other relatives of former President Hashemi Rafsanjani also were arrested.
