Ukraine talks 'productive' but more work needed, Rubio says

US Secretary of State Marco Rubio says talks with Ukraine over a deal to end the Russia-Ukraine war were productive, but there's "more work to be done".

The talks, held in Florida, were attended by a Ukrainian delegation led by national security council secretary Rustem Umerov, Ukraine's new chief negotiator.

Also at the meeting were President Donald Trump's envoy Steve Witkoff and Trump's son-in-law, Jared Kushner. Witkoff is due to travel on Monday to Moscow for talks with the Russian side, a US official told the BBC's partner CBS News.
