“The Council today imposed restrictive measures against two individuals and one body who were responsible for or participated in the cyber attack on the German federal parliament in April and May 2015,” the EU Council said in a statement.

The Official Journal of the EU states that sanctions are being imposed on the employees of the said GRU center.

Great Britain also joined the EU restrictive measures against these individuals and organizations.

"The UK will freeze accounts and ban two Russian GRU officers from entering its territory and impose sanctions against the GRU unit 26165, codenamed APT28 and Fancy Bear, which are responsible for the cyberattack on the German parliament in 2015," the British Foreign Office said.

In June, the Russian Foreign Ministry recalled that the Federal Republic of Germany had not provided evidence of Moscow's guilt in the cyber attack, not the Bundestag.

At the end of May, the German Foreign Ministry invited the Russian ambassador, where, as stated in Berlin, he was condemned because of the "hacker attack on the Bundestag."

The Russian Foreign Ministry, in turn, rejected Berlin's unsubstantiated accusations of the involvement of Russian government agencies in the hacker attack.

According to the official representative of the ministry, Maria Zakharova, this story was promoted as part of a media campaign, which "was built on the basis of some such half-hints, as well as leaks with links to some informed anonymous sources in the state apparatus of Germany."
