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, US 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. In response to Iran's repeated denials, and amid secret conversations with Iran's government, Secretary of State Hillary Clinton said in a statement in March 2011 that Levinson was being held somewhere in South Asia. The implication was that Levinson might be in the hands of terrorist group or criminal organization somewhere in Pakistan or Afghanistan. The statement was a goodwill gesture to Iran, one that the US hoped would prod Tehran to help bring him home. But nothing happened. Two years later, with the investigation stalled, the consensus now among some US officials involved in the case is that despite years of denials, Iran's intelligence service was almost certainly behind the 54-second video and five photographs of Levinson that were emailed anonymously to his family. Iranian President Mahmoud Ahmadinejad has personally and repeatedly criticized the US over its detention facility at Guantanamo Bay. US operatives in Afghanistan managed to trace the cellphone used to send the photographs, officials said. But the owner had nothing to do with the photos, and the trail went cold. It was that way, too, with the hostage video the family received. It was sent from a cyber cafe in Pakistan in November 2010. The video depicted a haggard Levinson, who said he was being held by a “group”. In the background, Pashtun wedding music can be heard. The Pashtun people live primarily in Pakistan and Afghanistan, just across Iran's eastern border. — AP
