Defeated candidate Mirhossein Mousavi demanded on Sunday that Iran’s presidential election be annulled and urged more protests, while tens of thousands of people hailed the victory of the hardline Mahmoud Ahmadinejad. Mousavi’s supporters again took to the streets after violence on Saturday, clashing with police in protests that have underscored political rifts exposed by Friday’s disputed vote. In a statement on his website, Mousavi said he had formally asked the Guardian Council, a legislative body, to cancel the election result. “I urge you, Iranian nation, to continue your nationwide protests in a peaceful and legal way,” he added.
