It looks like Tehran could see another clash of wills today. Iran's supreme leader says he's not giving in to pressure over the country's disputed election, but there's word that opposition supporters are planning another demonstration. Supreme Leader Ayatollah Ali Khamenei (hah-meh-neh-EE') has ordered protests to end. Appearing on state television today, Khamenei said he's insisting "on implementation of the law," and effectively closed the door on compromise with the opposition. Reformist candidate Mir Hossein Mousavi (meer hoh-SAYN' moo-SAH'-vee) claims that hard-line President Mahmoud Ahmadinejad (ah-muh-DEE'-neh-zhahd) stole the June 12 presidential election through massive fraud, and has called for a new vote. His official Web site says a protest has been planned for this afternoon, this time outside Iran's parliament. But the site describes it as independent and says it wasn't organized by Mousavi.
