Kyiv is renewing calls for more weapons 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 published on Sunday, Ukrainian Foreign Minister Dmytro Kuleba said the lack of weapons was the “number one” problem facing his country amid an invasion of Russia, and urged Berlin to speed up the delivery of its promise. He also called on the German government to begin training Ukrainian pilots to use Western fighter jets.
