The death toll from a Russian attack in southern Ukraine on a site where people had gathered to receive humanitarian aid rose to 29 on Tuesday, with 48 still missing, as a wave of overnight strikes targeted power plants across the country, damaged hospitals and wounded scores of people.

Dozens of rescuers and volunteers continued to search the cratered blast site of a destroyed aid facility and shelter in Komyushuvakha, a village in Ukraine's southern Zaporizhzhia region, hoping to find missing residents alive under the rubble.

Instead, more bodies were pulled out and carried away in white plastic sheeting.
