BOGOTA, Colombia — A former U.S. Marine who Colombia's main insurgency says it "captured" a month ago in a turbulent southeastern region is a tourist, not a member of the U.S. mission, and should be released immediately, Washington's ambassador said Saturday.
A Colombian police general said Kevin Scott Sutay, 26, had entered a hot zone against warnings.
The rebels offered to free Sutay as a good-faith gesture in announcing on their website Friday night that he was in their custody.
The Revolutionary Armed Forces of Colombia, or FARC, said Sutay had described himself as a 2010-11 veteran of the Afghan conflict who left the armed forces in March.
It did not say how it came to have Sutay but suggested he was "a mercenary."
U.S. Ambassador Michael McKinley denied that and also said Sutay was not an active member of the military.
"We understand that (he) was on a trip as a private citizen through Latin America," the ambassador told reporters when questioned about Sutay after attending a Mass marking Colombia's independence day. "He is a citizen who has nothing to do with Colombia's internal conflict."
The chief of Colombia's anti-kidnapping police, Gen Humberto Guatibonza, told The Associated Press that Sutay had spent from June 11-13 in the Las Palmas hotel in San Jose del Guaviare, where a Colombian military base is located, then attempted land travel to Puerto Inirida, capital of the eastern state of Guainia on Venezuela's border.
