The death toll from Russia’s heavy bombardment of Ukraine’s capital this week has risen to 31 people, marking the deadliest single attack on Kyiv in a year, Ukrainian officials said on Friday.

The reciprocal drone strikes followed a day of mourning in the Ukrainian capital Kyiv on Friday, after a Russian drone and missile attack killed 31 people, including five children, and wounded more than 150.

The residential building in the Sviatoshynskyi district was a “direct hit,” Tymur Tkachenko said in a message on Telegram.
