British Prime Minister Keir Starmer told a virtual meeting of about 25 world leaders on Saturday that they had to be prepared to defend any Ukraine peace deal themselves, urging them to keep up pressure on Russia. Meanwhile, Ukrainian President Volodymyr Zelenskyy said Saturday that the question of ceding territory in Ukraine's war with Russia was "complicated" and should be discussed in detail at a later date. He also said Ukraine would never recognize occupied territory as Russian.
