The death toll has risen to five after the collapse of an apartment block in Florida, authorities say.
Miami-Dade Mayor Daniella Levine Cava said the number unaccounted for has now dropped to 156, with three more of the recovered bodies identified.
“Our top priority continues to be search and rescue and saving any lives that we can,” she told reporters.
Part of the building collapsed early in the morning on Thursday while many residents slept.
The cause of the collapse remains unclear.
But an engineer’s report from 2018 was made public on Saturday, which highlighted “a major error” in the original design of the seafront Champlain Towers in the town of Surfside, near Miami. It said the fault prevented water draining away from the base of the building.
President Joe Biden tweeted that he had offered “assistance as needed” to Florida Governor Ron DeSantis.
Teams have been using machines, drones and specially trained dogs in their efforts to find survivors. Rescue efforts were briefly hampered on Saturday after a fire broke out underneath the rubble.
Ms Levine Cava said the death toll increased after emergency workers found a body in the rubble on Saturday. Four of the five confirmed fatalities have been identified – they include the mother of a boy who was pulled alive from the rubble on Thursday.
The Miami-Dade mayor said the search efforts had also uncovered some human remains, but warned that the process of identifying these victims was “very difficult” and would rely on DNA testing.
The missing include people from Israel and Latin America, according to reports. Paraguay’s foreign ministry said six of its nationals had been registered as missing, including the sister of the country’s first lady.
Local officials have provided families with hotel rooms and food as they wait for news about their loved ones.
