The Kremlin warned of a further deterioration in German-Russian relations if Berlin delivers Leopard battle tanks to Ukraine. “Such shipments do not bode well for the future of relations,” Kremlin spokesperson Dmitry Peskov said on Tuesday, according to the news agency Interfax. Poland has said it intends to send its German-made tanks to Ukraine, but Berlin has not said it will do the same. Moscow had repeatedly criticized Western arms deliveries to Ukraine as an escalation in the war.
