KYIV, Ukraine (AP) — An overnight Russian missile and drone bombardment of Ukraine killed 15 people and injured 156, local officials said Tuesday, with the main barrage demolishing a nine-story Kyiv apartment building in the deadliest attack on the capital this year.

It was the deadliest attack on the Ukrainian capital in almost a year, and came as Moscow has intensified air assaults on the city.

Russia flattened a section of an apartment block in Kyiv on Tuesday in its deadliest attack on the Ukrainian capital this year — part of a barrage of hundreds of drones and dozens of missiles that killed at least 18 people and wounded 151 others.
