Belarusian President Alexander Lukashenko — Russian President Vladimir Putin’s closest ally — warned Western nations of a coming World War III, unless they stop supplying Ukraine with weapons. Lukashenko, 68, raised the specter of a global conflict in a letter to United Nations Secretary-General Antonio Guterres, which was released Monday. “Belarus calls on the countries of the world to unite and prevent the regional conflict in Europe from escalating into a full-scale world war!” he wrote, according to reporting by Newsweek.
