A burning electrical smell filled the air and photos of missing people hung on a fence near the rubble of a 12-story beachfront condominium building that collapsed just north of Miami early in the morning. Nearly 160 people are still unaccounted for and at least four are dead. Thick smoke coming from the remains of Champlain Towers South darkened the sky and made it difficult to breathe. Officials said a fire continued to burn underneath the rubble, despite efforts to put it out. A wing of the residential building in Surfside, Florida, came down with a roar around 1:30 a.m. On video footage captured from nearby, the center of the building appeared to fall first, with a section nearest the ocean teetering and coming down seconds later as a huge dust cloud swallowed the neighborhood. Surfside Mayor Charles Burkett told USA TODAY the rescue efforts will continue "until we pull everybody we can out of that rubble." "We will not stop. You can count on us to continue this search until we find every person who's alive in that rubble." #surfside #surfsidebeach #miami
