Donald Trump and Volodymyr Zelensky said progress had been made to end the Ukraine war during Florida talks but the US president admitted the problem of territory remained "unresolved".

While both the US and Ukrainian presidents described the talks as "great", Trump said "one or two very thorny issues" remained outstanding - most notably on the issue of land, BBC reported. 

Addressing reporters at Mar-a-Lago, Zelensky said they had come to an agreement on "90%" of the 20-point peace plan, while Trump said a security guarantee for Ukraine was "close to 95%" done.
