The FBI has set up a Persian-language Facebook page to ask for information on the whereabouts of former FBI agent Robert Levinson, who went missing during a 2007 trip to Iran's Kish Island.
The Facebook page, which went online in January, appeals directly to the Iranian public for information about Levinson’s disappearance.
The page includes several photographs of Levinson and personal details about him.
The Associated Press reports that similar pages also are planned in Arabic and Urdu.
Facebook is banned in Iran but many access it through antifiltering tools.
The FBI is offering a reward of $5 million for information that could lead to Levinson's safe return.
White House Press Secretary Josh Earnest said on January 19 that Washington thinks Levinson is alive but no longer in Iran.
Levinson's family members have said they were devastated he was not part of the prisoner exchange between Washington and Tehran that took place In January.
Iranian officials say Tehran does not have information about Levinson's location.
