A FORMER Russian president has warned that any attempt to arrest Vladimir Putin abroad would be seen as “a declaration of war” in a chilling threat to the West. The International Criminal Court (ICC) issued an arrest warrant for Vladimir Putin last week, for war crimes relating to the invasion of Ukraine. Dimitri Medvedev said in a video posted to Telegram late on Wednesday: “Let’s imagine — obviously this situation which will never be realized — but nevertheless lets imagine that it was realized: The current head of the nuclear state went to a territory, say Germany, and was arrested. “What would that be? It would be a declaration of war on the Russian Federation. And, in that case, all our assets — all our missiles etc — would fly to the Bundestag, to the chancellor’s office.” It comes after Medvedev earlier warned of a “nuclear apocalypse” due to the constant arms supply to Ukraine, writing: “Has the threat of a nuclear conflict passed? No, it has not passed. It has increased. Each day when foreign weapons are delivered to Ukraine ultimately brings this same nuclear apocalypse closer.” Read our Ukraine war blog below for the latest news…
