The US President Joe Biden visited surfside Florida on Thursday to mourn with the families of those who were killed and missing in the collapse of the Florida Condominium Complex a week ago.

The death toll has reached 18 so far which included 4 y/o and 10 y/o children. 145 people are still supposed to be trapped inside the rubble dead or alive.

President Biden pledged federal assistance and offered comfort to the family of the killed and missing.

Fire Rescue Chief Alan Cominsky said search teams would confine their work to three of nine grid areas in the ruins. The mayor, too, citing ongoing uncertainty over the structural integrity of the site, said, “we’re continuing to restrict access to the collapse zone.”

It was unclear, however, whether areas reopened to the search were smaller than before operations were halted.

Biden acknowledged that hopes of finding any survivors dimmed with each passing day, but said it was possible someone might still be pulled out alive.
