After six more bodies found in the debris of the collapse condo in Florida, the death toll has risen to 18.

Nobody has been pulled alive from the site except for the early hours after the building collapsed.

Miami-Dade County Mayor Daniella Levine Cava told a news conference that 147 people are still missing inside the collapsed condo. She also added two of the dead are children aged 10 and 4.

“The loss of children is too great to bear,” Levine Cava said. “Our community, our nation, and the world all are mourning with these families who have lost loved ones.”

Officials have said they still harbor hope of finding survivors. Surfside Mayor Charles Burkett said in an interview he had promised families that rescue crews were “not leaving anyone behind” as teams dig deeper into the rubble.

“We’ve not gotten to the bottom. We don’t know what’s down there,” he said. “We’re not going to guess. We’re not going to make a life-or-death decision to arbitrarily stop searching for people who may be alive in that rubble.”
