Thousands stage new opposition rally in Tehran as pro-government demonstrators also take to the streets.

Supporters of Iran's defeated presidential candidate are again staging a mass rally in northern Tehran as the government mustered thousands of its supporters in Vali Asr Square. This comes a day after seven people were killed in clashes on the fringes of a huge opposition rally which saw hundreds of thousands of supporters of Mir Hossein Mousavi and other opposition leaders, take to the streets, alleging fraud in Friday's presidential election which returned Mr Ahmadinejad to office.

iNewsit members have stated crowds the size of those at Monday's opposition rally have not been seen in Tehran since the 1979 revolution.
