US special envoy Steve Witkoff arrives in Moscow amid Ukraine ceasefire tensions.

US Special Envoy Steve Witkoff has arrived in Moscow, where he was welcomed at the airport by Russia’s investment envoy, Kirill Dmitriev, according to a source involved in organizing the visit, Reuters reported on Wednesday.

Witkoff’s visit comes as US President Donald Trump issued a warning that sanctions would be imposed on Russia if it does not agree to a ceasefire in Ukraine by Friday. Trump had earlier indicated that Witkoff might be heading to Moscow this week.

A separate source familiar with the matter confirmed on Tuesday that Witkoff was scheduled to hold talks with Russian leadership on Wednesday.
