A Turkish police officer stands in front of people waiting for visas near the side entrance of the U. S. embassy, unseen, three days after a suicide bomber attack, in Ankara, Turkey, Monday, Feb. 4, 2013. The suicide bomber who struck the U.S. Embassy in Ankara spent five years in prison on terrorism charges but was released after being diagnosed with a hunger strike-related brain disorder, officials said Saturday. The bomber, identified as 40-year-old leftist militant Ecevit Sanli, killed himself and a Turkish security guard on Friday, in what U.S. officials said was a terrorist attack.(AP Photo/Burhan Ozbilici) less
