Fire spread through an 28-storey skyscraper under construction in Abu Dhabi on Tuesday, adjacent to Beach Rotana Hotel and Abu Dhabi Mall, reported Trade Arabia.

The fire is said to be the latest in a series of at least five fires that broke in tall buildings located in the UAE over the last 18 months.

The fire purportedly started from the top 20 floors in the commercial building, as firefighters were working to put the blaze out two hours after it started. Workers, guests and staff were all evacuated from site by the civil defense, stated Reuters.

Another fire broke out in July in the 75-storey residential Sulafa Tower in Dubai’s upscale Marina District. Another blaze took place in February 2015 in  a 79-storey residential tower in the emirate.

Experts have claimed that such incidents resulted from exterior cladding used for decoration and insulation.

In 2013, the UAE revised its building safety code, stipulating that cladding on all new buildings over 50 feet tall be fire-resistant except for older buildings.
