The Iranian government crackdown on the media appears harsher than initially believed: 24 journalists and bloggers have been jailed in the country, including an Iranian-Canadian journalist working for Newsweek. Maziar Bahari was detained without charges by the authorities on Sunday and he has not been heard from since. "Newsweek strongly condemns this unwarranted detention, and calls upon the Iranian government to release him immediately," said the magazine in a statement. Newsweek reports that several security officers arrived at Bahari’s Tehran apartment, did not identify themselves, and then left with the journalist after taking his laptop and videos. According to Reporters Without Borders, the head of the Association of Iranian Journalists has also been detained, and Life magazine reports an Iranian photojournalist who shot photos on their Web site is also missing.
