A Dubai Marina tower was evacuated in the early hours of Wednesday after its car park roof collapsed.
Police and Civil Defence were called to Dorra Bay Tower at about 1am when the car park floor caved in.
Neighbours described a loud boom and shaking in the 21-storey building.
Workmen were at the scene on Thursday to assess the damage. It appears the street-level surface caved in and exposed the sub-level parking below.

A security guard said there were no vehicles in the affected area. No injuries were reported.
One tenant said they were told a water pipe had burst and flooded the basement, causing a foundation wall to crumble. Officials did not confirm that and have not yet released details.
Residents were taken to nearby hotels for two nights while an investigation, structural work and repairs get under way. Some tenants currently overseas learnt about the incident on social media.
The building management will cover the costs of a two-day stay during the work, it was reported.
