VIDEO: Residential building collapses in South Florida, killing at least one

• One person died and 10 others were wounded when a Florida condo building collapsed early on Thursday.
• Rescuers are still searching for 51 people who are unaccounted for, officials said.
• It is likely that officials will find more victims in the rubble.

At least one person died after a 12-story residential building partially collapsed in South Florida on Thursday.

Hundreds of fire and rescue workers are scouring through tons of rubble in search of 51 people who are still unaccounted for.

Thirty-five people were rescued from the building, according to fire officials. Rescuers used trained dogs in drones in their search for survivors. It is possible that more victims could be found in the rubble, officials said.

Built in 1981, the Champlain Towers South had more than 130 units, about 80 of which were occupied. It is unclear how many people were inside at 1:30 a.m., when an entire side of the building pulled away and fell to the ground below. Construction work had been underway on the roof for more than a month, but it was unclear if that was related to the collapse.

Residents said the collapse sounded like a thunderstorm.
