Rescuers focus on survivors, 159 missing in Miami condo collapse

Officials say there is still hope of finding people alive as crews use dogs and microphones to survey the wreckage.

Rescue workers scouring the debris of a collapsed condo building in a Miami suburb in the southern US state, Florida, continued to search for survivors on Friday, as officials raised the number of people unaccounted for to 159 and the confirmed death toll to four. With many firefighters working overnight both from under and atop the remains of the building, hopes rested on how quickly crews using dogs and microphones to sift through the wreckage could complete their grim, yet delicate task. “It’s heartbreaking but our only focus right now is search and rescue, that’s all we’re doing, search and rescue, search and rescue, search and rescue 24 hours a day,” Surfside Mayor Charles Burkett told NPR on Friday.
