The family of a former U.S. federal agent missing in Iran since March says Iranian authorities have blocked a U.S. request for Swiss diplomats to visit his last known location.
Former Federal Bureau of Investigation agent Bob Levinson was last seen in the Iranian resort of Kish Island while on a business trip.
His wife, Christine Levinson, told the Washington Post that she is particularly interested in locating her husband's missing duffle bag. She did not provide further details.
The Iranian government has denied any knowledge of the missing man, but the U.S. State Department says it finds that claim hard to believe.
