Spain says U.S. tipoff led it to query Bolivian flight

MADRID (Reuters) - Spain acknowledged on Tuesday that a U.S. request had led it to delay approving an overflight by Bolivia's president, but said it had given the go-ahead after receiving an assurance from Bolivia that U.S. fugitive Edward Snowden was not on the plane.

Bolivia has accused Spain, France, Portugal and Italy of closing their skies to President Evo Morales' plane last week after being told it was carrying the former U.S. spy agency contractor from Moscow to Bolivia, and demanded to know who gave them that information.
