Kerry pushes for a deal in second day of talks on Afghan vote crisis --- (Reuters) - U.S. Secretary of State John Kerry scrambled to produce a deal by the end of Saturday to end Afghanistan's election crisis, meeting for the second day with the country's two presidential candidates and incumbent President Hamid Karzai. -- The deadlock over the June 14 election run-off between the leading contenders, Abdullah Abdullah and Ashraf Ghani, has raised concerns in Washington about a smooth transition of power in Afghanistan just as U.S. troops are withdrawing. -- Kerry and his aides met throughout the night, following talks on Friday with both Abdullah and Ghani, as well as with Karzai and U.N. special envoy to Afghanistan Jan Kubis. -- He met again with Abdullah and Ghani at the U.S. compound on Saturday and will meet Karzai at the presidential palace later. -- A news conference is scheduled for Saturday afternoon before Kerry flies to Vienna for talks between world powers and Iran on Tehran's nuclear program. - More, http://www.reuters.com/article/2014/07/12/us-usa-afghanistan-kerry-idUSKBN0FH06R20140712
