Anger at the official result saw hundreds of thousands of Mousevi supporters take to the streets on Monday, alleging fraud in the poll which returned Mr Ahmadinejad to office. LATEST NEWS Jon LeyneReporting from Tehran Eyewitnesses, including a reporter for the state run Press TV station, say a huge opposition rally has gathered in north Tehran. It is not organised, and it is not clear if any opposition leaders will attend. But the crowd is moving up past the offices of the state broadcaster IRIB.
New restrictions imposed by the government mean that foreign reporters are not allowed to attend opposition rallies. But one eyewitness told me that he believed there were more people even than yesterday's huge rally, which was attended by hundreds of thousands, possibly millions, of opposition supporters.
Another rally of government supporters was held in central Tehran. From the television pictures, the size was not clear, but it does not appear to have been on the scale of the opposition gatherings.

Since that rally, the authorities have imposed tough new restrictions on foreign journalists operating in Tehran - the most sweeping restrictions our correspondent in Tehran, Jon Leyne, says he has ever faced.
They must now obtain explicit permission before leaving the office to cover any story.
Journalists have also been banned from attending or reporting on any "unauthorised" demonstration - and it is unclear which if any of the protests are formally authorised.
Press cards have been declared invalid.
