Miami Building Collapse: Death toll climbs to 18, nearly 150 missing

The death toll in the Florida collapsed building rose to 18, after bodies of two children were found in the rubble.

Nobody has been pulled alive from the disaster site shortly after the structure caved in on Thursday.

Rescue teams have been able to build a ramp for a crane to reach areas of the ruined building that they had not been able to access before.

Nearly 150 people are still missing after the collapse last Thursday.

The latest victims to be found have not yet been publicly identified.

Seven days after the collapse in the town of Surfside, north of Miami, officials say they are still hopeful that some survivors could be found trapped in the debris.

Rescue teams say they are working 12-hour shifts as they comb the rubble, despite sweltering heat and high humidity hampering their efforts.

Fresh rescue teams are due to arrive from other states, with severe tropical weather expected to hit the area in the coming days.

As well as bad weather, search and rescue teams have also faced fires and falling debris.

What caused nearly half of the 40-year-old Champlain Towers south block to fall as residents slept in the early hours of last Thursday remains unknown.

US President Joe Biden and his wife Jill plan to visit the scene of the tragedy on Thursday.
