Kyiv is renewing calls for more ammunition and stronger air defenses after Russia fired half a dozen hypersonic missiles at Ukraine last week. In an interview with Germany’s Bild am Sonntag newspaper that published Sunday, Ukrainian Foreign Minister Dmytro Kuleba said ammunition shortages were the “number one” problem his country was facing and urged Berlin to speed up promised deliveries. He also called on the German government to begin training Ukrainian pilots to use Western fighter jets.
