A picture obatained from the election campaign website of Iran’s defeated presidential candidate Mir Hossein Mousavi, GHALAMNEWS.IR, shows one of his supporters holding up a placard with Arabic and Farsi writing that reads "what crime did you die for?" during a massive rally in Tehran on June 18, 2009. Tens of thousands of Mousavi supporters demonstrated for a sixth straight day, keeping up the pressure on the Islamic regime over the disputed vote. The protesters wore black as a mark of mourning for demonstrators killed in clashes during previous protests in the Iranian capital, which have been banned by the authorities.
