TEHRAN, Iran (AP) - Witnesses and opposition websites say police in Tehran have used tear gas to disperse anti-government protesters demanding the release of opposition leaders.

kaleme.com says protesters rallied at several points in the capital Tuesday, chanting “death to the dictator” and calling on authorities to free Mir Hossein Mousavi and Mahdi Karroubi.

Family members and opposition activists say the two leaders have moved from house arrest to a Tehran prison along with their wives. Iranian authorities deny the reports.

Witnesses say police fired tear gas to disperse dozens of protesters on Keshavarz Boulevard in central Tehran. They say several people were arrested.
