The prospect for a ceasefire between Russia and Ukraine "is in Moscow's hands," a top aide to Ukrainian President Volodymyr Zelenskyy said following talks with the U.S.

Two senior Ukrainian officials say a Kyiv delegation that will meet with America’s top diplomat in Saudi Arabia will propose a ceasefire with Russia covering the Black Sea and long-range missile strikes.

Kremlin spokesperson Dmitry Peskov told reporters Wednesday that Russia must get the details on U.S.-Ukrainian cease-fire talks before commenting on the proposal.
