Miami building collapse leaves at least four dead and 159 unaccounted for

A total of 159 people are now unaccounted for - and at least four people have been killed - following the collapse of an apartment building in Florida.

Three more bodies were pulled from the rubble during what Miami-Dade mayor Daniella Levine Cava described as a "tragic night".

"The search and rescue team worked throughout the night and it was a very active scene from above and from below," she said.

A fire official said rescuers could hear sounds at the site throughout the night.
