Officials in Colombia have released video of three American defense contractors and a former presidential candidate who were captured by rebel forces years ago.
Authorities say the footage was seized in an arrest of three suspected rebels yesterday.
The American hostages were captured by the Revolutionary Armed Forces of Colombia in 2003 after their surveillance plane went down in a jungle.
The fourth hostage, a dual French national, was captured while campaigning as a presidential candidate in 2002.
The tapes are the first images in years providing evidence that the captives may be alive. Officials say they were apparently recorded as recently as a month ago.
The rebels are offering to release these and other hostages in exchange for the release of hundreds of rebels from Colombian and U.S. prisons.
