Rescuers redouble efforts at collapsed Florida building, 150 still missing

SURFSIDE, Fla - With 150 people still missing nearly a week after the collapse of a Florida high-rise condominium, authorities on Tuesday said rescuers had redoubled efforts to find any survivors even as officials sought to explain the formidable hurdles facing search teams.

Miami-Dade County Mayor Daniella Levine Cava told reporters that no bodies had been recovered from the rubble since Monday, keeping the official death toll at 11. What caused a major section of the 40-year-old building to suddenly crumble into a heap remains under investigation. Initial attention has focused on structural deficiencies described in a 2018 engineer's report.
