Petition for Maziar Bahari, held in Tehran

CPJ will be collecting signatures until July 31 on a Facebook petition in support of Maziar Bahari, Newsweek's Tehran correspondent, who is being held without charge in Iran.

Bahari, who is also an internationally acclaimed filmmaker, was detained on June 21 as part of Iran's post-election crackdown on the media. More than 100 prominent journalists from around the world signed a similar petition calling for Bahari's release on July 15.
