Rescuers search around the clock for survivors of Florida building collapse

SURFSIDE, Florida: Prospects for recovering survivors from a Florida high-rise diminished with each passing hour on Saturday, two full days after the 12-story condominium mysteriously collapsed while many residents slept.

Even so, search-and-rescue teams worked around the clock through an unstable mountain of debris looking for signs of life from any of the 159 people still unaccounted for, while smoldering fires filled the air with smoke. The death toll of four was certain to rise with one floor of the high-rise stacked atop another like pancakes. Aided by dogs, cameras, sonar and heavy equipment, rescuers looked for any spaces that may have formed in the debris, leaving any possible survivors air to breathe.
