Ukrainian President Volodymyr Zelensky pressed for more weapons support during a meeting Friday with top US military leaders and more than 50 partner nations in Germany, as Washington announced it would provide another $250 million in security assistance to Kyiv.

US Defense Secretary Lloyd Austin said the meeting of the leaders was taking place during a dynamic moment in Ukraine’s fight against Russia, as it conducts its first offensive operations of the war while facing a significant threat from Russian forces near the Donbas.
