U.S. Senator John Kerry (C) shakes hands with the United Nations Special Envoy to Afghanistan Kai Eide after his speech during a news conference with Afghan President Hamid Karzai in Kabul October 20, 2009. Karzai must face an election run-off against his main rival on Nov. 7, officials said on Tuesday, to resolve a disputed first round that plunged the country into months of political uncertainty. Karzai welcomed the ruling by the government-appointed Independent Election Commission (IEC) after hours of closed-door meetings with western diplomats and mounting international pressure to accept the need for a second round.
