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.

An American citizen was among at least 28 people killed in a deadly and huge Russian strike on Kyiv overnight Tuesday.

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