Authorities in South Florida were responding early Thursday to a "partial building collapse", the Miami-Dade Fire Rescue said.
It's not known how many people had been in the building and there was no word on how many people could be injured.
The oceanfront condominium, which was built in the 1980s, has over 100 apartment units and was believed to be substantially full when a third of it collapsed in the early morning hours, according to Burkett.
CBS News reported that at least one person is dead and people are being extracted from the collapse.
"Over 80 MDFR units including #TRT (Technical Rescue Teams) are on scene with assistance from municipal fire departments", the tweet said. Two were in critical condition.
