Angry Shi'ites marched Wednesday to protest remarks made on a talk show on Al-Jazeera television, in which a Sunni guest criticized Iraq's Shi'ite religious leaders.
Fadel al-Rubaei, a Sunni politician living in exile, said Shi'ite clerics should not take part in politics and accused them of conspiring with the Americans against the mostly Sunni insurgents.
The statements angered many Shi'ites, including many who did not see the Al-Jazeera show but saw reports on an Iraqi station, Al-Furat, owned by the biggest Iraqi Shi'ite party.
Al-Furat said that legislator Abdul-Aziz al-Hakim, head of the Supreme Council for the Islamic Revolution in Iraq, "condemns violations against Shi'ites religious leaders broadcast through one of satellite channels known for its hatred to the Iraqi people."
Al-Jazeera officials in Qatar were not available for comment.
