KYIV: The death toll from a Russian strike on a warehouse west of Kyiv, described as the war's deadliest attack this year, rose to 38, with four people still missing, Ukrainian President Volodymyr Zelenskyy said Sunday.

The Friday night strike hit a warehouse that Ukrainian officials said was storing ammunition, causing massive explosions and fires that spread to dozens of nearby homes and buildings in the village of Myla.

Russia has sharply intensified its air campaign in the 4 1/2-year-old conflict, with air raid sirens wailing repeatedly and explosions and the rumble of air defenses resounding across Kyiv throughout the day.

Zelenskyy said on social media that emergency workers continued to extinguish fires and identify and neutralize explosives at the site. At least 52 people were reported affected, though further details were not provided in the report.
