US and Russian officials began talks in Saudi Arabia on Monday aimed at making progress toward a broad ceasefire in Ukraine with Washington eyeing a Black Sea ceasefire deal before securing a wider agreement.

The talks, which followed US talks with Ukraine on Sunday, come as US President Donald Trump intensifies his drive to end the three-year-old conflict after he last week spoke to both Ukrainian President Volodymyr Zelensky and Russian President Vladimir Putin.

A source briefed on the planning for the talks said the US side was being led by Andrew Peek, a senior director at the White House National Security Council, and Michael Anton, a senior State Department official.

The White House says the aim of the talks is to reach a maritime ceasefire in the Black Sea, allowing the free flow of shipping.

Russia will be represented by Grigory Karasin, a former diplomat who is now chair of the Federation Council’s Foreign Affairs Committee, and Sergei Beseda, an adviser to the director of the Federal Security Service.
