US sees signs of life for FBI agent who disappeared in Iran

WASHINGTON - The United States said on Thursday it has seen recent indications that a former FBI agent who vanished in Iran in 2007 is being held in southwest Asia, a rare public signal that it has reason to believe he is alive.
US Secretary of State Hillary Clinton appealed to Iran to help find the man, Robert Levinson, and to reunite him with his family despite past US frustration that Tehran had ignored US pleas for information about him.
