The family of Robert Levinson has released a video in which the missing ex-FBI agent pleads for help from the US government. In the video, Levinson urges Washington to help him "answer the requests of the group that has held me for three and a half years," without indicating who that group is, or what those requests might be. "Please help me get home," he says. "Thirty-three years of service to the United States deserves something."
Levinson went missing in Iran in March 2007 while investigating cigarette smuggling as a private investigator. Earlier this year his family said they had proof he was alive, which may have been this video. The family received the video last November, and sources tell the New York Times that its release a full year later indicates that the government's search for Levinson is going poorly. The video is accompanied by a message from Levinson's wife and one of his sons, who beg his captors to reveal their demands. (Read more Robert Levinson stories.)
