Iran's top legislative body, the Guardian Council, says it is prepared to recount some of the disputed votes from Friday's presidential elections.

Defeated opposition leader Mir Hossein Mousavi has accused President Mahmoud Ahmadinejad of electoral fraud and is demanding that the result of the election - which gave President Ahmadinejad a landslide win over his rival - be declared invalid.  The Guardian Council has rejected that request but wants a recount in the jurisdictions where the results have been contested.

It is expected that demonstrators will rally again in Tehran today. Mr Mousavi is urging his supporters to stay at home in a bid to avoid any violence. On Monday, at least eight people were killed in mass demonstrations in Tehran against the re-election of President Ahmadinejad. Despite a ban on demonstrations, hundreds of thousands of opposition supporters took to the streets of the capital in a public outpouring of anger reminiscent of the 1979 marches of the Islamic revolution. Protesters set tyres, dustbins and motorbikes ablaze. The violence flared after the defeated opposition candidate appeared in public for the first time since the election and addressed the crowds.

Iran is facing an international backlash against its crackdown on the opposition protesters and the election itself. The EU has called for an inquiry into the conduct of the election. President Barack Obama, who has offered dialogue with Iran after three decades of US hostility, said he was "deeply troubled" by the violence.

If there are more demonstrations today, foreign journalists will have to work from their offices as the Culture Ministry says it is cancelling press accreditation for all foreign media.
