Morales' plane was diverted to Austria overnight after leaving Russia where some suspected he had smuggled Snowden out of the Moscow airport in order to attain asylum in Bolivia, which is among the 20 countries where the former National Security Agency was seeking refuge.
"This is a hostile act by the United States state department which has used various European governments," said Saavedra, who was also aboard the flight. Austrian spokesmen said Snowden was not on board the Bolivian leader's plane. Snowden is wanted for espionage in the U.S.
