Senior Pentagon officials have arrived in Ukraine to "discuss efforts to end the war" with Russia, the US military has said.
The team, led by US Army Secretary Dan Driscoll, held talks with Ukrainian Prime Minister Yulia Svyrydenko on Thursday morning. They are expected to meet Ukrainian President Volodymyr Zelensky later in the day.
Reports began surfacing on Wednesday that the US and Russia had prepared a new proposed framework to end the war, requiring major concessions from Ukraine including giving up territory and dramatically shrinking its military.
It was reportedly drafted by President Donald Trump's envoy Steve Witkoff and Russian special envoy Kirill Dmitriev.
