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.

An overnight Russian drone and missile attack on Ukraine’s capital Kyiv has killed at least 18 people, including a six-year-old boy, as well as wounding 159 others, according to Ukrainian officials, prompting United States President Donald Trump to slam Moscow’s actions as “disgusting.”

Ukrainian President Volodymyr Zelensky has called for stronger international sanctions on Russia after a deadly attack on Kyiv killed at least 31 people. Zelensky said five children - the youngest aged two - were among the dead and 159 people had been wounded in the assault on Thursday.
