KYIV: 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.

A two-year-old was among the five children found dead after Thursday’s sweeping Russian drone and missile attack, President Volodymyr Zelensky said on Friday, announcing the end of a more than 24-hour-long rescue operation.

A total of 159 people were wounded in the multi-wave strike, in which Russia launched more than 300 drones and eight missiles early on Thursday, the latest in a campaign of fierce strikes on Ukrainian towns and cities.

The worst damage was to an apartment building that partially collapsed in the Sviatoshyn district in western Kyiv. Damage was also reported in at least three other districts of the capital.

US President Donald Trump on Thursday sharply criticized Russia’s “disgusting” behavior against Ukraine, while saying he was not sure whether sanctions would deter Russia. He has given President Vladimir Putin until August 8 to make a deal or else he will respond with economic pressure.
