A screenshot from a video showing concrete raining down inside the apartment block.

Footage from inside a Florida apartment shows concrete falling from the ceiling moments before the building partially collapsed.

A large section of Champlain Towers South in Miami collapsed at around 1.30 a.m. on Thursday.

At least one person is dead, and authorities fear many more have died. Ninety nine people are currently missing.

The video shows white dust falling inside an apartment, and a loud noise before the footage cuts out.
