The deadly crash of a helicopter that killed Ukraine's interior minister and about a dozen other people outside the capital, Kyiv, on Wednesday is the latest in a series of devastating developments in the nearly yearlong war that began with Russia's invasion.
The crash came four days after a Russian missile struck an apartment building i n Ukraine's southeastern city of Dnipro, killing dozens of civilians, including six children. That attack was the deadliest on civilians since the spring.
