Bolivia leader's jet diverted 'amid Snowden suspicions'
Bolivian President Evo Morales's plane had to be diverted to Austria amid suspicion that US intelligence leaker Edward Snowden was on board, the Bolivian foreign minister has said.
Officials in both Austria and Bolivia said Mr Snowden was not on the plane.
France and Portugal reportedly refused to allow the Moscow-Bolivia flight to cross their airspace.
Mr Snowden is reportedly seeking asylum in Bolivia and 20 other countries to avoid extradition to the US.
Bolivian Foreign Minister David Choquehuanca told reporters on Tuesday that France and Portugal had closed their airspace over the "huge lie" that Mr Snowden, 30, was on board.
"We don't know who invented this lie, but we want to denounce to the international community this injustice with the plane of President Evo Morales," he said.
The Bolivian defence minister, also on the flight, pilloried the US after the unscheduled landing.
"This is a hostile act by the United States state department which has used various European governments," Ruben Saavedra said.
The Falcon aircraft was reportedly allowed to refuel in Spain before the jet went on to Vienna. President Morales was said to be at the airport in Vienna discussing his return route to Bolivia early on Wednesday.
French officials said they could not confirm whether they had denied permission for President Morales' plane to fly over their territory. Portuguese officials could not immediately be reached for comment.
The Bolivian president had been on a visit to Moscow, where Mr Snowden, a former CIA contractor, has reportedly been holed up in an airport transit area since arriving from Hong Kong on 23 June.
President Morales told Russian television that Bolivia had not yet received an application from Mr Snowden, however, his request, if sent, would be considered.
"Bolivia is ready to accept people who disclose espionage if one can call it this way," he said.
Mr Morales and Venezuelan President Nicolas Maduro had been in Moscow for a meeting of gas-exporting countries.
President Maduro said he had not formally received an asylum request, but expressed support for Mr Snowden, saying he "deserves the world's protection" from the United States.
"Why are they persecuting him? What has he done? Did he launch a missile and kill someone? Did he rig a bomb and kill someone? No. He is preventing war," he told Reuters news agency.
Spy chief's apology

He is wanted by the US on charges of leaking secrets he gathered while working as a contractor for the National Security Agency (NSA), America's electronic spying agency.
On Tuesday, National Intelligence Director James Clapper apologised for telling Congress in March that the NSA did not have a policy of gathering data on millions of Americans.
He said in a letter to Dianne Feinstein, head of the Senate intelligence committee, that his answer had been "clearly erroneous".
The leaking of thousands of classified intelligence documents prompted revelations that the US has been systematically seizing vast amounts of phone and web data.
Wikileaks, which says it is advising Mr Snowden, said most of his asylum requests had been handed to the Russian consulate at Moscow's Sheremetyevo airport late on Sunday for delivery to the relevant embassies in the capital.
