"I would not like to comment on the report of Bild, this news outlet does not hesitate to use fake news," Peskov told reporters.
Earlier in the day, German newspaper Bild reported that it has obtained a "secret document" prepared by the German armed forces (Bundeswehr) alleging that Russia has a plan to attack NATO's eastern flank after a successful counteroffensive against Ukraine and pushback of the Ukrainian army by June.
Later in the day, the German Defense Ministry commented on Bild's report, saying that considering even highly unlikely scenarios is part of the art of war.
"Examining various scenarios, even if they are highly unlikely, is part of the art of war, especially in military training," the ministry said in response to a query from Bild.
Russia has been vocal over the past years about NATO's unprecedented activity along its western border, saying that NATO is expanding its presence under the pretext of "deterring" perceived "Russian aggression." Moscow has repeatedly expressed concern about the buildup of NATO forces in Europe. The Kremlin has said that Russia is not threatening anyone, but will not ignore actions that are potentially dangerous to its interests.
