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.

Ukrainian rescuers recovered more than a dozen more bodies from the rubble of a collapsed apartment block in Kyiv overnight, bringing the death toll from Russia's worst air strike of the year on Ukraine's capital to 31.
