Iranians demonstrate near Quai d’Orsay, the French Foreign Affairs Ministry, in Paris, Thursday June 18, 2009, protesting the outcome of the presidential election in Iran. Iranian opposition leader Mousavi called his supporters into the streets of Tehran Thursday for a fourth day of protests and urged them to dress in black to mourn those killed in violent clashes over the disputed presidential election. The call for opponents of President Mahmoud Ahmadinejad to rally again was in open defiance of the country’s supreme leader, who has urged the nation to unite behind the Islamic state.
