A high-rise tower caught fire on Tuesday in Sharjah, a city of United Arab Emirates.

The sides of the 48-floor Abbco Tower in Sharjah saw flames shoot up them. Firefighters and police surrounded the tower, as did curious onlookers. Authorities offered no immediate cause for the blaze.

The UAE, including skyscraper-studded Dubai, has suffered a spate of fires in its high-rises in recent years.

The reason for the blazes, building and safety experts say, is the material used for the buildings’ sidings, called aluminum composite panel cladding.
