TEHRAN, Iran (CNN) — As Iran extended the deadline Tuesday to file complaints about the disputed presidential election, one candidate lashed out at the hardline government while another went the opposite direction and withdrew his accusations.The “assaults, beatings and murder of innocent people” were committed by plain-clothed security forces, not by demonstrators as the Iranian media would like its audiences to believe, Karroubi said in an open letter addressed to Ezattollah Zarghami, which was posted on Karroubi’s Web site.
