US President Donald Trump has said Kyiv can "win all of Ukraine back in its original form", marking a major shift in his position on the war with Russia, BBC reported.

In a post on his Truth Social platform, he said Ukraine could get back "the original borders from where this war started" with the support of Europe and Nato, due to pressures on Russia's economy.

His comments came after talks with Ukrainian President Volodymyr Zelensky, held after Trump had addressed the UN General Assembly in New York on Tuesday.

Trump has repeatedly expressed his desire to end the war, but has previously warned that process would likely involve Ukraine giving up some territory, an outcome Zelensky hasconsistently rejected, according to BBC.
