The rescue session of the collapse of a Florida apartment building has continued on Friday morning and dozens have remained unaccounted for.

So far, at least four persons has been confirmed dead in the rubble of the partially collapsed residential building in South Florida.

According to officials, there are still people, numbering about 99 who might probably be under the mountain of debris, CNN reports.

Miami-Dade County Mayor Daniella Levine Cava confirmed the incident occurred on Thursday in the beachfront community of Surfside, a few miles north of Miami Beach.

On how the collapse occurred, officials have also disclosed that, about 55 of the 136 units at Champlain Towers South crumbled at around 1:30 a.m. Thursday, leaving huge piles of rubble on the ground and materials dangling from what remained of the structure.

As the rescue mission continues, the efforts are being intensified to make sure there are positive results. One concerned personality who is passionately working towards this goal is Surfside Mayor, Charles Burkett.

On Thursday, he made comments on the situation. He said, “We’re not giving up,”

“That is the one thing we’re not doing.

We’re searching 24 hours a day, and we’re pulling as many people out as we can. That’s the whole goal right now. Nothing else matters.”

The major reason for the collapse has not been immediately ascertained.
