Thousands of opposition supporters have clashed with security forces in the centre of the Iranian capital, Tehran.

Police used tear gas and detained dozens rallying in solidarity with uprisings in Egypt and Tunisia. There was one report of a death in Tehran.

The BBC also received reports of similar protests being held in the cities of Isfahan, Mashhad and Shiraz.

Earlier, the police placed opposition leader Mir Hossein Mousavi under house arrest, according to his website.

It said the move was intended to prevent the former prime minister attending the march in Tehran, which the authorities had prohibited. The road leading to Mr Mousavi's house was also blocked by police vans.

Fellow opposition leader Mehdi Karroubi, a former speaker of parliament and a senior cleric, is also reportedly under de facto house arrest.

BBC News - Iran police fire tear gas at opposition rally in Tehran Not unexpectedly, the regime in Tehran has responded with force, using tear gas, paintballs and clubs to disperse peaceful protesters. They have also begun jamming satellite news programs and censoring the internet. I guess they missed that face that these measures failed in Egypt.

This could get interesting. It could also get very bloody. Unlike Egypt, I don't thing the Iranian military is going to refuse to attack protestors.
