Germany and Russia should discuss results of the investigation of the hacker attack on the Bundestag carried out in 2015, Bundestag Vice President Petra Pau said.
"The prosecutor general explained to us in the Bundestag a few weeks ago that an international arrest warrant was issued for one person who is an employee of the Russian intelligence services, that this is the result of an investigation. I do not want and cannot evaluate it. This should be discussed at the interstate level with each other, also if criminal prosecution is necessary," Pau said.
Earlier on Thursday, Russian Ambassador to Germany Sergey Nechaev was summoned to the German Foreign Office over the attack.
"State secretary of the Federal Foreign Office, Miguel Berger, has invited Russian Federation Ambassador Sergey Nechaev to the Federal Foreign Office for today's talks. On behalf of the federal government, he firmly condemned the hacking attack on Germany's Bundestag," the ministry said in a statement.
"The Russian ambassador was told that the federal government in Brussels will apply the European Union's cybersanctions regime against people responsible for the attack on Germany's Bundestag, including Badin," the Foreign Office added.
The German Foreign Office stressed it had evidence that Badin was an officer of the Main Directorate of the Russian armed forces' General Staff, known by abbreviation GRU.
"The warrant for Badin's arrest was issued due to suspicions that the offender, acting with other people, whose names have not been identified yet, engaged in intelligence activities against the Federal Republic of Germany in the interests of a foreign nation's special service. He is suspected of being involved in the hacking attack on German Bundestag in April-May 2015, as a member of a group ... There is reliable evidence that at the moment of the attack he worked for the GRU military intelligence service," the statement read on.
Earlier in May, German prosecution issued an arrest warrant for a Russian suspect, allegedly involved in the 2015 hacking of emails from computers in the Bundestag. German media said he was a military intelligence officer, named Dmitry Badin. Russia has repeatedly denied claims of being behind hacking attacks.
