Two leading reformist dailies in Iran did not publish today after printing a letter critical of supreme leader Ayatollah Ali Khamenei. Journalists say the "Eqbal" and "Aftab-e Yazd" newspapers were closed last night on orders of the Tehran Prosecutor's Office. It is not clear how long the newspapers will be barred from publishing. The open letter to Khamenei was sent by moderate cleric Mehdi Karroubi. Karroubi came third in last week's presidential election. In his letter, Karroubi said military organizations broke the law by supporting hard-line Tehran Mayor Mahmoud Ahmadinejad. Ahmadinejad came second in the poll. He will now contest a run-off on Friday against former President Akbar Hashemi Rafsanjani. State media in Iran carried no reports on Karroubi's letter. Criticizing the supreme leader is a crime in Iran. Many journalists have been tried and dozens of newspapers closed in Iran for similar offences in recent years.
