Russian President Vladimir Putin said that not inviting Moscow to the Auschwitz liberation events was “strange “and “shameful”. Putin also said the matter could have been handled more subtly and that the relatives of Soviet soldiers who liberated the camp could have been invited if it was not possible to invite the soldiers due to health or age.

Ukrainian President Volodymyr Zelenskyy says that excluding his country from talks between the U.S. and Russia about the war in Ukraine would be “very dangerous.”

Trump's Ukraine envoy said Sunday that both Kyiv and Moscow would have to make concessions if they are to successfully negotiate a solution to the ongoing war.
