The U.S. and Russia are expected to release a joint statement on Tuesday morning after discussions in Saudi Arabia aimed at achieving a Black Sea maritime ceasefire deal, sources familiar with the matter told CBS News.

The closed-door talks at the Ritz-Carlton Hotel in Riyadh follow U.S. consultations with a Ukrainian delegation on stabilizing the front lines and implementing a proposed 30-day armistice.

U.S. and Russian officials wrapped up day-long talks on Monday focused on a narrow proposal for a ceasefire at sea between Kyiv and Moscow, part of a diplomatic effort that Washington hopes will help pave the way for broader peace negotiations.
