More mass protests are expected in the Iranian capital after presidential challenger Mir Hossein Mousavi urged followers to observe a day of mourning. Mr Mousavi has called on supporters to stage peaceful protests or gather at mosques in memory of eight people killed after a Tehran rally on Monday. He has also called for the release of a growing number of pro-reform activists. The top legislative body has invited the three defeated candidates to a meeting on Saturday, state radio says.
