Afghanistan goes to the polls

An Afghan election worker, left, sprays on the finger of a voter to make sure she did not vote earlier, at a polling station in Kabul, Afghanistan, Saturday, April 5, 2014. A finger of the voter who once casts a ballot is inked at a polling station. Afghan voters lined up for blocks at polling stations nationwide on Saturday, defying a threat of violence by the Taliban to cast ballots in what promises to be the nation's first democratic transfer of power.
