Ambulances rushed to the scene of a music festival in Miami on Thursday evening, after a large section of the stage collapsed and a giant LED screen fell, injuring at least two workers.

Officials say the large LED screen crashed onto the main stage as workers were preparing for the 2013 Ultra Music Festival.

Fire rescue workers took the injured employees to a nearby trauma centre. Two workers were reported to have head injuries and other fractures, according to local media outlets.

The festival is scheduled to begin on Friday and run over two weekends.
