KYIV, Ukraine (AP) — At least 37 people have been killed following a Russian strike close to the Ukrainian capital of Kyiv, officials said Saturday, one of the deadliest attacks to hit Ukraine this year.

The attack sparked a fire in the Bucha district, west of Kyiv, that swept through homes and damaged at least 50 residential buildings, said Tymur Tkachenko, head of the local regional military administration.
