US President Trump's envoy, Steve Witkoff, met with Russian President Vladimir Putin in Moscow on Friday to discuss an envisioned strategy to end the Ukraine war, raising concerns among Kyiv and European allies over conditions perceived to be too advantageous to Moscow, Reuters reported.

The encounter, Witkoff's third with Putin, comes amid rising suspicion in Ukraine and Europe. Kremlin footage showed a formal sit-down with top Russian officials.

A day earlier, Trump condemned a deadly Russian strike on Kyiv but claimed progress in peace talks, warning both sides that if negotiations stalled, the US would withdraw.
