The claim that the Ukraine-Russia war is over is completely false. On the day writing, this Wednesday, April 29th, and Article from CBS News came out. The article, titled 'Trump speaks with Putin, says he isn't sure whether Ukraine war or Iran war will end first' from the title alone speaks about how the war is still going. It goes on to talk about Trump's talks with Putin that he has had. One thing it did mention was that Putin may hold a ceasefire day for a holiday, which is Victory Day (the day Russia defeated Nazi Germany). Other than that, there has been no signs of Russia holding back from the war and no signs of the war being over. In addition to this, BBC News is holding a part on their page which tracks the Russia-Ukraine war and gives updates through articles every time something substantial happens. For the second part of the claim, it says Ukraine's Zelensky has fled Ukraine. Looking it up, there has been no news articles or proof of him escaping the country in worry that Russia will assassinate. Overall, this claim is full on false and not to be taken seriously.
