Another body was recovered on Tuesday from the ruins of a Florida condominium tower, the mayor said, raising the death toll in the collapse to at least 12 with 149 people still listed as missing.

Iran PressAmerica: The latest casualty of the disaster, which could ultimately rank as the worst accidental building collapse in U.S. history, was not immediately identified by Miami-Dade County Mayor Daniella Levine Cava during an afternoon news conference.

Florida emergency management director Kevin Guthrie said local authorities on Tuesday had asked the federal government to send additional urban search and rescue teams to the scene in the town of Surfside.

A 12-story, 136-unit apartment complex near Miami Beach in the US partially collapsed early Thursday morning.

The collapse of the building was first reported to the authority at 1:23 a.m., when most of the residents were asleep, raising fears that the number of casualties could increase further. 219
