A man looks in Moscow on May 14, 2013, at a computer screen displaying a photo published by Russian state English language television RT website, which shows a man, identified as Ryan C. Fogle, the third secretary of the political section of Washington&#39;s embassy in Moscow (L), being escorted by a Russia&#39;s Federal Security Service (FSB, ex-KGB) agent (R) during his arrest. Russia said today it had detained an alleged American CIA agent working undercover at the US embassy who was discovered with a large stash of money as he was trying to recruit a Russian intelligence officer.
