Some senior European politicians yesterday lined up to condemn the US for using Cold War-style tactics against its allies, threatening ongoing negotiations over a US-EU free trade pact.
Martin Schulz, the president of the European Parliament, said the EU was demanding "full clarification and require[s] further information speedily from the US authorities".
"If the allegations prove to be true, it would be an extremely serious matter which will have a severe impact on EU-US relations," said Schulz.
The latest top-secret documents were released by Edward Snowden, the former NSA contractor who has exposed a series of classified operations since fleeing his job at a listening post in Hawaii in May.
Germany's Justice Minister, Sabine Leutheusser-Schnarrenberger, described the allegations as "reminiscent of methods used by enemies during the Cold War".
"If these reports are true, it's disgusting," said Luxembourg's Foreign Minister, Jean Asselborn. "The EU and its diplomats are not terrorists. We need a guarantee from the very highest level that it stops immediately."
France's Foreign Minister, Laurent Fabius, said he had "asked the American authorities for an explanation".
Meanwhile, Ecuadorean President Rafael Correa said Snowden was "under the care of the Russian authorities" and unable to leave Moscow's international airport without their consent, telegraphing the diminishing possibility that the leaker will end up in Ecuador.
Correa portrayed Russia as the master of Snowden's fate and said Ecuador was still awaiting an asylum request from him before deciding its next moves.
