Ukrainian President Volodymyr Zelensky has rejected proposals for a buffer zone between Ukrainian and Russian forces as part of a peace deal, arguing it does not reflect the realities of modern warfare.
"Only those who do not understand the technological state of today's war propose a buffer zone," he told reporters on Friday.
His comments followed a report suggesting European leaders were considering a 40km (25-mile) buffer zone as part of either a ceasefire or longer-term agreement.
The war in Ukraine has evolved into a conflict driven by drone technology, and Zelensky suggested a buffer zone of sorts already existed because of the threat of drone strikes close to the front line.
Buffer zones can create demilitarised zones between warring countries, such as North and South Korea, and physical boundaries such as the Iron Curtain - which separated the Soviet Union and the West following World War Two.
