"The use of information and communication technologies for malicious purposes and against democratic institutions is unacceptable," Borrell wrote on his Twitter page.

Earlier, the European Union and Great Britain imposed sanctions against two citizens of Russia and the “85th Main Center of Special Services of the GRU”, considering them to be involved in the hacker attack on the Bundestag in 2015.

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 on the Bundestag.

At the end of May, the German Foreign Ministry invited the ambassador of Russia, and, as they said 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.
