WASHINGTON – Two years after a hostage video and photographs of retired FBI agent Robert Levinson raised the possibility that the missing American was being held by terrorists, U.S. officials now see the government of Iran behind the images, intelligence officials told The Associated Press.

Levinson, a private investigator, disappeared in 2007 on the Iranian island of Kish. The Iranian government has repeatedly denied knowing anything about his disappearance, and the disturbing video and photos that Levinson's family received in late 2010 and early 2011 seemed to give credence to the idea.

The extraordinary photos – showing Levinson's hair wild and gray, his beard long and unkempt – are being seen for the first time publicly after the family provided copies to the AP. The video has been previously released.
