“We are all concerned about the buildup of military power in Russia along the eastern border of Ukraine,” von der Leyen wrote on Twitter.

According to her, the European Union is ready to resolutely respond to any aggression against Ukraine.

Earlier, Russian President Vladimir Putin said that Russia has never become hostile to other states.

Also, the press secretary of the Russian president Dmitry Peskov, in an interview with an RT correspondent, emphasized that in Moscow they see "numerous ducks" that are thrown about the allegedly planned "aggression" of Russia against Ukraine.
