Bruno Kahl, president of the Bundesnachrichtendienst, said Russia may have been behind attempts during the US presidential campaign to interfere with the vote.

“We have evidence that cyber-attacks are taking place that have no purpose other than to elicit political uncertainty,” he told the Süddeutsche Zeitung in his first interview since he was appointed five months ago.

“The perpetrators are interested in delegitimizing the democratic process as such, regardless of who that ends up helping. We have indications that [the attacks] come from the Russian region.
