Mousavi, moderate challenger rejected the tally as a "dangerous charade" that could lead to tyranny

          Mousavi protested against what he said were many obvious violations in the high-turnout presidential election."I'm warning I will not surrender to this dangerous charade. The result of such performance by some officials will jeopardize the pillars of the Islamic Republic and will establish tyranny," Mousavi said in a statement made available to Reuters. He had been due to hold a news conference, but police at the building turned journalists away, saying it was cancelled. Iranian and Western analysts abroad greeted the results with disbelief. They said Ahmadinejad's re-election would disappoint Western powers aiming to convince Iran to halt work they suspect is aimed at making bombs, and could further complicate efforts by U.S. President Barack Obama to reach out to Tehran. "It doesn't augur well for an early and peaceful settlement of the nuclear dispute," said Mark Fitzpatrick at London's International Institute for Strategic Studies. A bitterly fought campaign generated strong interest around the world and intense excitement inside Iran. It revealed deep divisions among establishment figures between those backing Ahmadinejad and those pushing for social and political change. Ahmadinejad accused his rivals of undermining the Islamic Republic by advocating detente with the West. Mousavi said the president's "extremist" foreign policy had humiliated Iranians. On Friday night, before official results emerged, Mousavi had claimed to be the "definite winner". He said many people had been unable to vote and ballot papers were lacking. He also accused authorities of blocking text messaging, with which his campaign tried to reach young, urban voters. (14,28)
