Talks with Kyiv 'substantive', will continue 'as long as it takes': US envoy Witkoff

US envoy Steve Witkoff said talks he held with Ukrainian leader Volodymyr Zelensky and his team in Kyiv Sunday on ending the war with Russia were "substantive" and would continue.

"We've had a very meaningful discussion, substantive, important, and we are very encouraged and we look forward to continuing this as long as it takes," Witkoff said after the talks.
