The Russian invasion of Ukraine has been described as a "rehearsal" for a world war by an analyst on the country's state TV.
Professor Alexei Fenenko, a leading research fellow at the Institute of International Security Studies, signalled on the state-controlled channel Russia-1 that a future conflict could be with The North Atlantic Treaty Organisation (Nato).
Speaking on a discussion panel this week, Prof Fenenko used the term "war" - as opposed to the Kremlin's insistence that the Ukraine invasion was a "special military operation" - and suggested more was to come.
