Russia launched a massive attack on Ukraine overnight into Saturday with hundreds of drones, killing at least one person, part of a stepped-up bombing campaign that has dashed hopes for a breakthrough in efforts to end the more than 3-year-old war.

Russia launched over 30 missiles and 300 drones during its overnight assault that affected 10 regions of the country, Ukrainian President Zelenskiy said.

Russian missile strikes killed three people across Ukraine on Saturday, while Ukrainian drone attacks briefly halted train services in Russia’s Rostov region. The conflict, now in its third year, continues to escalate despite mounting international pressure and new EU sanctions targeting Moscow’s war funding. Shirli Sitbon has this story.
