A partial collapse of the under-construction Hard Rock Hotel in New Orleans, USA has left one person dead.
At least two people were left unaccounted for and several injured in the incident on Saturday morning, New Orleans-based television station WDSU cited officials as saying.
All of the injured people were in a stable condition and some had been discharged, Dr Emily Nichols, Medical Director of New Orleans Emergency Medical Services said.
New Orleans Fire Department (NOFD) Chief Tim McConnell said at a press conference that emergency services believed they knew where the two individuals were but that they had "no visibility (on them) at this time.
The department had sent drones to try and locate the pair, he said, adding the NOFD believed it could reach one person while it was "not sure" if rescuers could get to the other.
Engineers from the city were meeting to determine how to get to the second individual, McConnell said.
The location is not stable and there is currently a possibility of further collapse of the crane, he added.
Footage shared by the channel showed the moment of the collapse.
The emergency response hub in New Orleans, NOLA Ready, said the fire, ambulance and police departments were all responding at the scene.
Clearing the site was going to be a long term operation, Collin Arnold, Homeland Security and Emergency Preparedness said.
Traffic restrictions had been set and first responders were going into the building, he added.
