SURFSIDE, Florida: A beachfront condo building partially collapsed on Thursday outside Miami, killing at least one person and trapping others in the tower that resembled a giant fractured dollhouse, with one side sheared away. Dozens of survivors were pulled out, and rescuers kept up a desperate search for more.

A wing of the 12-story building in the community of Surfside came down with a roar around 1:30 a.m. By late evening, nearly 100 people were still unaccounted for, authorities said, raising fears that the death toll could climb sharply. Officials did not know how many were in the tower when it fell.
