Turkish Foreign Minister Mevlüt Çavuşoğlu said on Thursday that Russian oligarch Roman Abramovich, who is sanctioned by European nations over Russia's invasion of Ukraine, was "sincerely" working to end the war.
He has been liaising between Kyiv and Moscow since the invasion began on Feb. 24, Çavuşoğlu said.
Abramovich made a surprise appearance at Ukraine-Russia negotiations in Istanbul on Tuesday.
