The largest known Russian drone attack since full-scale war began in 2022 killed a woman in the Kyiv region and injured at least three people, Ukrainian authorities said early on Sunday, as Moscow stepped up strikes following peace talks on Friday.

Russia launched 273 drones by 8 a.m. local time (0500 GMT), targeting chiefly the central Kyiv region and the Dnipropetrovsk and Donetsk regions in the country’s east, Ukraine’s air force said.

Based on data provided by the air force, this was Russia’s largest drone attack on Ukraine of the war. On the eve of the third anniversary of Russia’s full-scale invasion of Ukraine on February 23, Moscow launched a then-record 267 drones.
