Updated at 12:40pm with news of one death and 3:13pm with comments from crane owner.

At least one person has been killed and three people injured after part of a construction crane collapsed near F Ring this morning, the manager of the company that planned to use the crane has said.

Witnesses who spoke to Doha News said the crane fell across both sides of traffic near the old Airforce Roundabout around 10am, creating massive traffic backups in the area.

One motorist said she saw an ambulance onsite treating people for their wounds.

Several photos of the scene being passed around on social media show a body covered in a blue sheet and blood splattered on the crane crash site.

What happened

According to an official from local construction company MedGulf, which owned the crane, a subcontractor had been in the middle of installing the device when it toppled over.

He told Doha News that the crane had not yet been operational, and that the windy weather may have contributed to the collapse. One of the people who was working on the installation was killed, he added.

The company and police are investigating the accident, the manager said, continuing:

“God rest his soul in peace and we sincerely hope something like this doesn’t happen in the future.”

Several hours after the accident, the Ministry of Interior commented that police were on site to direct traffic, but did not say how many injuries and fatalities occurred.

An accident led to partial closure of road from Air Force signal to Parachute signal, authorities taking procedures to ensure traffic flow.

As police work to clear the crane, traffic was being rerouted onto F-Ring Road through side streets.
