Spain says it has asked the United States to use its talks on taking Cuba off the blacklist of nations sponsoring terrorism to help obtain the extradition of two members of the armed Basque group ETA from the communist country.

Foreign Minister Jose Manuel Garcia Margallo said Monday the government has been in talks with the U.S. in the hope of getting Cuba to extradite Jose Angel Urtiaga and Jose Ignacio Etxarte to Spain.

They are wanted since 2010 in a probe into alleged links between Venezuela, ETA and the Colombian rebel group, the FARC.

Cuba's 33-year status on the terrorism list stems from its support decades ago for ETA and the FARC.

The list is a major hurdle in U.S.-Cuban negotiations to end a half-century diplomatic freeze.
