Ukrainian President Volodymyr Zelenskyy has reaffimed his firm refusal to cede any territory, resisting U.S. pressure for a painful compromise with Russia as he continued to rally European support for Ukraine.

“Undoubtedly, Russia insists for us to give up territories. We, clearly, don’t want to give up anything. That’s what we are fighting for,” Zelenskyy said in a WhatsApp chat late Monday in which he answered reporters’ questions.

“Do we consider ceding any territories? According to the law we don’t have such right. According to Ukraine’s law, our constitution, international law, and to be frank, we don’t have a moral right either.”
