A helicopter crashed in fog near a nursery outside Kyiv on Wednesday, killing 14 people, including Ukraine's interior minister, in what President Volodymyr Zelenskyy called a "terrible tragedy," before calling for an investigation.

The crash set off a large fire, and an entire side of the local nursery building was charred. The Kyiv region's governor said children and staff had been in the nursery at the time of the crash shortly after 8 a.m.

Several bodies lay on the ground of a courtyard, their boots sticking out from under blankets, after the helicopter — described by the air force spokesperson as a French Super Puma — slammed into a building in Brovary, northeast of the capital.
