In Russia, a major oil terminal near the port of Novorossiysk stopped operations Saturday after a strike by unmanned boats damaged one of its three mooring points, according to a statement from the Caspian Pipeline Consortium, which owns the terminal.

Russia launched its largest barrage of drones and missiles in a month across Ukraine, killing at least three people, Ukrainian President Volodymyr Zelensky said Saturday, as a Kyiv delegation heads to the United States for fresh peace talks.

Ukraine’s chief negotiator, in an exclusive interview, says conceding sovereign territory is off-limits in peace talks.

Russian drone and missile attacks in and around the Ukraine's capital killed at least three people early Saturday, officials said, as the country's representatives traveled to the U.S. to work on a renewed push to end the war.

Zelensky didn't reveal much detail about an updated plan, although he said there needed to be more investment for drones.

None of us really know what Zelenskyy is like operating solo, because he never has," Michael Bociurkiw, a nonresident senior fellow at the Atlantic Council’s Eurasia Center, told NBC News.

President Donald Trump's top officials are meeting with a team of Ukrainian negotiators. Trump has been trying to broker an end to Russia's war in Ukraine since he took office.

Russian President Vladimir Putin said that a US plan to end the war in Ukraine could “form the basis for future agreements” but renewed threats to seize more territory by force unless Kyiv withdraws.
