Cutting off yet another avenue that Iranian protesters hoped could yield results, Iran's Guardian Council said Friday that no significant fraud had taken place in this month's disputed elections. "The Guardian council has almost finished reviewing defeated candidates' election complaints ... the reviews showed that the election was the healthiest since the revolution ... There were no major violations in the election," the council's spokesman said, according to Reuters. The decision comes as the mass protests of last week have dwindled thanks to a violent police crackdown. Nonetheless, Iranians upset with the election still are finding ways to register their displeasure, chanting "Allahu Akbar!" at night from their rooftops, for example. On Friday, supporters of Mir Hossein Mousavi, who has not given up his challenge of the election results, release thousands of green and black balloons in tribute to Neda Agha Soltan, who was killed during the protests.
