President Donald Trump supports Russian leader Vladimir Putin's proposal for Moscow to take full control of the Donbas and freeze the front lines elsewhere for a deal with Ukraine.

Russian Foreign Minister Sergei Lavrov held calls on Saturday with his Turkish and Hungarian counterparts, the Russian foreign ministry said, hours after a summit between the U.S. and Russian presidents yielded no deal on ending the war in Ukraine.

The traditionally Russian-speaking area is at the heart of what the Russian president calls the “root causes” of the war, and taking it over is near the top of his list of territorial and political demands.

The highly anticipated summit ended without a breakthrough. Afterwards, Trump said Ukraine and Russia should proceed straight to seeking a full peace deal instead of a cease-fire.

President Trump and Russian President Vladimir Putin are scheduled to meet Friday at Joint Base Elmendorf-Richardson in Anchorage, Alaska, to discuss the conflict between Russia and Ukraine.

President Trump offered security guarantees to deter future Russian aggression. But the offer was vague, prompting Kyiv to seek clarity.
