Russia has launched its most intense drone attack on Ukraine since the beginning of its full-scale invasion in 2022, Ukrainian officials confirmed to the Associated Press.

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 and Ukraine’s first direct talks in three years began Friday with hopes as dim as the gray Istanbul skies.
