Iran Police Crack Down On Protests

Defeated Iranian presidential candidate Mirhossein Mousavi has said he is "ready for martyrdom" as his supporters clashed with police in Tehran.

His backers were demonstrating over the re-election of hardline President Mahmoud Ahmadinejad, who won by a landslide despite opposition claims the result was rigged.

The protesters defied a call from the country's supreme leader for the demonstrations to end.

Ayatollah: 'UK Is Most Treacherous'

Iran's supreme leader has insisted there was no vote-rigging in a presidential election and attacked "enemies" - naming the UK government as the "most treacherous".

Anger after President Mahmoud Ahmadinejad was re-elected led to the biggest street demonstrations in the Islamic Republic's history.
