Iran election dispute fans unrest

Mahmoud Ahmadinejad, Iran's incumbent president, has defended his disputed re-election at a public rally in Tehran, insisting that the vote was not "distorted" as claimed by his rivals. The speech was delivered amid reports of arrests of several reformist politicians who supported Mir Hossein Mousavi, Ahmadinejad's main challenger, and a formal appeal by Mousavi for the cancellation of Friday's vote.Supporters of the conservative Ahmadinejad, waving Iranian flags and his portraits filled the capital's Valiasr Square on Sunday to listen to his speech after the authorities declared that he had won a second four-year term by a huge margin over Mousavi."Elections in Iran are the cleanest. But some inside or outside Iran have come out and said the elections have been distorted. Where is the distortion in the election?" Ahmadinejad said as the crowds shouted "Bravo Ahmadi!"
