The damaged remaining portion of a collapsed South Florida apartment building has been demolished with explosives as rescuers try to reach new areas of the rubble in the search for victims.

After demolition crews set off the explosives a number of explosions could be heard and then the building started to fall, sending up massive plumes of dust into the air in the surrounding neighbourhoods.
