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.

A Russian drone attack on a bus in northeastern Ukraine killed at least nine people and injured seven others, Ukrainian officials said Saturday, just hours after the two countries met for the first direct peace talk in three years.

This comes after the first direct talks between Moscow and Kyiv in years on Friday failed towards attempt of ceasefire.
