A partial recount of Iran's disputed presidential vote is under way. The country's top electoral authority says it's aimed at gaining the confidence of "respectable supporters" of the candidates and should be complete by the end of the day. Reformist candidate Mir Hossein Mousavi (meer hoh-SAYN' moo-SAH'-vee) contends there was massive fraud and that the results should be nullified. Iranian media report the recount involves a random 10 percent of the ballots cast. It's unclear what purpose will be served as both supreme leader Ayatollah Ali Khamenei (hah-meh-neh-EE') and the country's top electoral oversight body already have pronounced the results free of major fraud, insisting that incumbent President Mahmoud Ahamdinejad (ah-muh-DEE'-neh-zhahd) won in a landslide.
