The Iranian opposition website, Kaleme, reported Tuesday that tear gas was fired at the anti-government demonstrators in Tehran to disperse them. On its part, the Sahammnews website earlier reported a large number of security forces had been deployed on the capital's main streets and in some of the main squares to prevent opposition supporters gathering.
These reports come after Iran's prosecutor-general, Gholam-Hossein Mohseni-Ejeie, dismissed news that the two prominent opposition figures - Mir Hossein Mousavi and Mehdi Karoubi - had been imprisoned. A local news agency quoted him as saying that reports they had been arrested were baseless.
On Monday, opposition sources said the two men and their wives were moved to Heshmatiyeh prison in Tehran.
