Sweden has been aiding the United States in spying on Russia, according to a new document leaked by Edward Snowden.
Swedish public TV, Sveriges Television, reports the document it obtained indicates the Swedish National Defence Radio Establishment (FRA) — the country’s intelligence agency — has been working with the National Security Agency to spy on Russian leaders.
FRA spokesman Fredrik Wallin said “no comment,” when the TV station asked for his reaction to the document.
According to Sweden’s report, the NSA document was dated April 18 of this year.
The document is one in a long line of leaks from Snowden that have raised tensions between the U.S. and allies in Europe. Snowden has been granted temporary asylum in Russia.
Other Snowden leaks have revealed spying by the U.S. on foreign citizens in Spain and France and on world leaders. There have also been revelations about the NSA monitoring the phones of allied leaders, including German Chancellor Angela Merkel.
President Obama has ordered a review of the NSA’s surveillance programs, due Dec. 15.
