Iran's Intelligence Ministry says that it has arrested a number of 'main agents', who masterminded the recent post-election violence in Tehran.

"The Intelligence Ministry has identified and arrested a number of the main agents and elements behind acts of vandalism in recent days in Tehran," said Intelligence Minister Gholam-Hossein Mohseni Eje'i.

He added that the Intelligence Ministry has a responsibility to arrest and prosecute members of 'some groups which enter public rallies and attempt to cause unrest and chaos'.

Earlier Wednesday, the Intelligence Ministry provided the country's parliament with a report of the recent unrest, which has so far resulted in the death of eight people.

In Tehran, Anti-riot police have clashed with supporters of defeated presidential candidate Mir-Hossein Mousavi, who reject the election as fraudulent. The clashes spread to the Tehran University dormitory on Sunday.

Iran's parliament Speaker Ali Larijani has blamed the Interior Ministry for the raid on the dorm and attacks on civilians.

On Wednesday, Iran's Interior Minister, Sadeq Mahsouli, ordered an investigation into the attacks.
