Russian Deputy Foreign Minister Sergey Ryabkov told ABC News during an exclusive interview in Moscow on Monday that he believes the warring parties are close to a deal.

The U.S. has agreed to provide unspecified security guarantees to Ukraine as part of a peace deal to end Russia's nearly four-year war, and more talks are likely this weekend, U.S. officials said Monday following the latest discussions with Ukrainian President Volodymyr Zelenskyy in Berlin.

At least two people were killed in a drone attack in Russia’s southwestern Saratov region and parts of Ukraine went without power following targeted assaults on energy infrastructure, local authorities said Saturday,

Ukraine has used long-range drones to attack Russian oil platforms as it expands its strikes on the country's energy sector.

The European Union is set to lock up Russia’s assets in Europe until Russia ends its war on Ukraine and compensates for the damage.

The founder of Russia's opposition Yabloko party, which wants a ceasefire in Ukraine, has said his party will keep campaigning despite the arrest of two senior figures, a move he said was meant to derail it before next year's parliamentary election.
