Foreign minister says no trace in Iran of missing ex-FBI agent

There are no traces in Iran of the former FBI agent who disappeared there six years ago, Iranian Foreign Minister Mohammad Javad Zarif said on CBS's "Face The Nation" on Sunday.

Robert Levinson, who became a private detective after retiring from the FBI in 1998, disappeared during a trip to an Iranian island in 2007. The White House says he was not a government employee at the time. (Reuters)
