The largest Russia-US spy swap since the Cold War appeared to be in motion Thursday, with a Russian convicted of spying for the United States reportedly plucked from a Moscow prison and flown to Vienna.
Defense lawyers in the US say they hoped for an immediate resolution for their 10 clients charged with spying for Russia.
A swap would have significant consequences for efforts between Washington and Moscow to repair ties chilled by a deepening atmosphere of suspicion.
Ten people accused of spying for Russia were set to appear at a hearing in New York federal court later Thursday. An 11th person charged in the case is a fugitive after jumping bail in Cyprus.
