The number of people who have died in the collapse of a high-rise apartment building in Miami has risen to 10.
Another 151 remain missing after part of the Champlain Towers building in the town of Surfside collapsed on Thursday.
The update came during a news conference on Monday afternoon in which it was revealed that experts who investigated the fall of the Twin Towers in the wake of 9/11 have been drafted in to investigate the incident.
US Congresswoman Debbie Wasserman Schultz said experts from the National Institute of Standards and Technology (NIST) are on site gathering preliminary evidence.
She told reporters: "They are the best of the best when it comes to making sure that they do a complete and thorough overview."
Governor Ron DeSantis cautioned that NIST's work looking into the cause of the collapse will "take a long time".
"It is something is going to be very thorough and is something that is not going to happen in a day or two. This is going to take a long time. "
