KYIV, Jan 6 – President of Ukraine Volodymyr Zelensky said that Russia would not be able to "hide in silence" its preparations for a new wave of aggression against Ukraine and all of Europe.

"The world will know in all details - how and when the aggressor is preparing a new escalation in this war. And every new mobilization step of Russia will be known to the world even before Russia makes it. We will ensure this," he said in a video message on Thursday.
