The Federal Bureau of Investigation has renewed its appeal for information regarding the disappearance of former FBI agent Robert Levinson, who went missing in Iran nearly two decades ago.

Levinson's case remains one of the bureau's most prominent unsolved missing person investigations. The FBI is offering a reward of up to $5 million for information leading to his location or recovery.

The former agent disappeared while on what was initially described as a private business trip to Iran's Kish Island in March 2007. His disappearance has since become a significant diplomatic and investigative matter between the United States and Iran.

Despite years of investigation and diplomatic efforts, Levinson's whereabouts remain unknown. The FBI continues to encourage anyone with information about his case to come forward.

The renewed appeal represents the bureau's ongoing commitment to resolving the case and bringing answers to Levinson's family after nearly 20 years of uncertainty.
