LONDON (Reuters) - Spy agencies across Western Europe are working together on mass surveillance of Internet and phone traffic comparable to programs run by their U.S. counterpart denounced by European governments, Britain's Guardian newspaper reported on Saturday.
Citing documents leaked by fugitive former U.S. National Security Agency (NSA) contractor Edward Snowden, the Guardian said methods included tapping into fiber optic cables and working covertly with private telecommunications companies.
The Guardian named Germany, France, Spain, Sweden and the Netherlands as countries where intelligence agencies had been developing such methods in cooperation with counterparts including Britain's surveillance agency GCHQ.
The report is potentially embarrassing for governments, especially in Germany and France which have been the most vocal in protesting about U.S. mass surveillance of European communication networks revealed by Snowden since June.
Germany, jointly with Brazil, circulated a draft resolution to a U.N. General Assembly committee on Friday that called for an end to excessive electronic surveillance, data collection and other gross invasions of privacy.
There has been particular anger in Germany, a close ally of the United States, over the revelation that the NSA monitored the mobile phone of Chancellor Angela Merkel.
Snowden has written an open letter to Merkel and other German authorities to say he is counting on international support to stop Washington's "persecution" of him.
Germany's BND federal intelligence service said there had been considerations in 2008 about merging German security services' surveillance of telecommunications, which would have required changes to telecommunication and security laws.
It said it had exchanged experiences with the British services on this in 2008 but these discussions had focused on technical rather than legal issues. The BND added that it regularly held such exchanges on technical developments with other European services.
"It is incorrect that Germany's BND federal intelligence service tried to circumvent legal restrictions to be able to implement British acquisition technology. On this point too the BND complied with the law," a BND spokesman said.
The Guardian said GCHQ files leaked by Snowden showed the British agency taking credit for advising European counterparts on how to get around domestic laws intended to restrict their surveillance powers.
"HUGE TECHNOLOGICAL POTENTIAL"
Citing a 2008 GCHQ country-by-country report, the Guardian said the British spies were particularly impressed with Germany's BND agency, which they said had "huge technological potential and good access to the heart of the Internet".
"We have been assisting the BND ... in making the case for reform or reinterpretation of the very restrictive interception legislation in Germany," the GCHQ document said, according to the Guardian.
The GCHQ had also praised France's DGSE agency and in particular its close ties with an unnamed telecommunications company, a relationship from which GCHQ hoped to benefit.
"We have made contact with the DGSE's main industry partner, who has some innovative approaches to some Internet challenges, raising the potential for GCHQ to make use of this company in the protocol development arena," the report said.
There was similar analysis of the intelligence agencies in Spain, Sweden and the Netherlands, with Spain's CNI praised for its ties with an unnamed British telecommunications firm and Sweden's FRA congratulated over a law passed in 2008 that widened surveillance powers.
Asked about the Guardian's report, Sweden's National Defense Radio Establishment (FRA) said it was natural that it had contacts with similar organizations in other countries.
FRA spokesman Fredrik Wallin said cooperation with foreign intelligence services could include exchanges of intelligence reports. He declined to comment on specific countries but said all activities were strictly controlled by Swedish law.
"There is a clear legal framework which determines how we cooperate with other countries," he said.
