Russia unleashed a major missile and drone barrage on Ukraine overnight into Saturday, while Ukrainian President Volodymyr Zelensky said he had a “substantive phone call” with American officials engaged in talks with a Ukrainian delegation in Florida, aimed at ending the nearly four-year war.

Russia used 653 drones and 51 missiles in the wide-reaching overnight attack on Ukraine, which triggered air raid alerts across the country and came as Ukraine marked Armed Forces Day, the country’s air force said Saturday morning.

Ukrainian forces shot down and neutralised 585 drones and 30 missiles, the air force said, adding that 29 locations were struck.

At least eight people were wounded in the attacks, Ukrainian Minister of Internal Affairs Ihor Klymenko said.

Among these, at least three people were wounded in the Kyiv region, according to local officials. Drone sightings were reported as far west as Ukraine’s Lviv region.

Russia carried out a “massive missile-drone attack” on power stations and other energy infrastructure in several Ukrainian regions, Ukraine’s national energy operator, Ukrenergo, wrote on Telegram.

Ukraine’s Zaporizhzhia nuclear power plant temporarily lost all off-site power overnight, the International Atomic Energy Agency said Saturday, citing its Director General Rafael Mariano Grossi.

The plant is in an area that has been under Russian control since early in Moscow’s invasion of Ukraine and is not in service, but it needs reliable power to cool its six shutdown reactors and spent fuel, to avoid any catastrophic nuclear incidents.

Zelensky said that energy facilities were the main targets of the attacks, also noting that a drone strike had “burned down” the train station in the city of Fastiv, located in the Kyiv region.

"The main targets of these strikes, once again, were energy facilities," Zelensky said earlier in the day on social media."Russia's aim is to inflict suffering on millions of Ukrainians."

As with previous waves of attacks, the Russian defense ministry said they had targeted"Ukrainian military-industrial complex enterprises and the energy facilities that support them", and added that"all designated targets were hit".

Russia’s Ministry of Defense said its air defenses had shot down 116 Ukrainian drones over Russian territory overnight into Saturday.

Russian Telegram news channel Astra said Ukraine struck Russia’s Ryazan Oil Refinery, sharing footage appearing to show a fire breaking out and plumes of smoke rising above the refinery. The Associated Press could not independently verify the video.

The General Staff of the Ukrainian Armed Forces later said Ukrainian forces had struck the refinery. Ryazan regional Governor Pavel Malkov said a residential building had been damaged in a drone attack and that drone debris had fallen on the grounds of an “industrial facility”, but did not mention the refinery.

Months of Ukrainian long-range drone strikes on Russian refineries have aimed to deprive Moscow of the oil export revenue it needs to pursue the war. Meanwhile, Kyiv and its Western allies say Russia is trying to cripple the Ukrainian power grid and deny civilians access to heat, light and running water for a fourth consecutive winter, in what Ukrainian officials call “weaponising” the cold.

The latest round of attacks came as US President Donald Trump’s advisers and Ukrainian officials said they’ll meet for a third day of talks on Saturday in Florida, after making progress on finding agreement on a security framework for postwar Ukraine.

Zelensky said Saturday that he had been given an update over the phone by US and Ukrainian officials at the talks.

“Ukraine is determined to keep working in good faith with the American side to genuinely achieve peace,” Zelensky wrote on social media.

Following Friday’s talks, the two sides had also offered the sober assessment that any “real progress toward any agreement” ultimately will depend “on Russia’s readiness to show serious commitment to long-term peace.”

The statement from US special envoy Steve Witkoff, Trump’s son-in-law Jared Kushner as well as Ukrainian negotiators Rustem Umerov and Andriy Hnatov came after they met for a second day on Friday. They offered only broad brushstrokes about the progress they say has been made as Trump pushes Kyiv and Moscow to agree to a US-mediated proposal to end nearly four years of war.

In Paris, French President Emmanuel Macron said he will meet Zelensky, British Prime Minister Keir Starmer and German Chancellor Friedrich Merz in London on Monday to"take stock" of the negotiations on the US-drafted plan.
