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.

Many Russian soldiers say they would see a cease-fire along the current front lines as a failure, hinting at the nationalist discontent the Kremlin could face in accepting a cease-fire.

Russia overnight into Sunday launched one of its most intense drone attacks on Ukraine since the beginning of its full-scale invasion in 2022. Russia fired a total of 273 exploding drones and decoys overnight, Ukraine’s air force said.
