US special envoy Steve Witkoff and US President Donald Trump’s adviser and son-in-law Jared Kushner spent hours at the Kremlin, departing in the early hours of Wednesday morning with no specific breakthrough on ending the conflict.

The path ahead for Ukraine peace talks is unclear, Trump said on Wednesday, after what he called "reasonably good" talks between Putin and US envoys.

Kremlin spokesman Dmitry Peskov said, “Some things were accepted, some things were marked as unacceptable. This is a normal working process of finding a compromise.”

Ukraine President Volodymyr Zelenskiy said in his nightly video address that his team is preparing for meetings in the United States and that the dialogue with Trump's representatives will continue.
