Nearly two dozen people have been evacuated from their condominiums in Puerto Rico's capital after a water tank collapsed through a residential building's roof.

There were no immediate reports of any deaths or significant injuries at the condominium complex in the wealthy Miramar neighborhood of San Juan.

Firefighters say roughly 20 people were left temporarily homeless after Sunday's incident.

Firefighters and engineers are trying to brace the building to prevent further collapse to the structure while utility workers check gas lines.
