Iran hardliners urge legal action against Mousavi

The semi-official Fars news agency said seven people linked to "anti-revolutionary" groups had been detained for taking part in "riots and unrest" in Tehran and the northwestern city of Qazvin.

Iran's police chief said on Wednesday 1,032 people had been detained during the protests in Tehran, but most had been freed.

The International Campaign for Human Rights in Iran said on Tuesday reports from within Iran indicated that as many as 2,000 people, including opposition leaders, professors, journalists, students and protesters may be in detention across the country.
