Ukrainian President Volodymyr Zelensky on Monday launched a fresh appeal for military aid as the country prepared for some of the conflict’s heaviest fighting so far, while France sent a police unit from its armed forces to Ukraine to investigate possible war crimes, the first disclosed deployment of military personnel in Ukraine from a North Atlantic Treaty Organization country.
Meanwhile, Ukrainian authorities said they were investigating a claim by its troops in the besieged city of Mariupol that they came under a Russian chemical weapons attack Monday. The Russian government hasn’t commented publicly regarding the alleged use of chemical weapons in Mariupol.
