A large fire ripped through a residential skyscraper in Dubai in the United Arab Emirates, engulfing the tower in flames.

Social media posts showed flames spreading up the Torch Tower as burning debris fell down early Friday morning.

BBC News reported the building was “successfully evacuated.”

It was not immediately clear what caused the blaze. At more than 80 stories, the tower is one of the world’s tallest residential structures.

In a tweet, authorities said there were no injuries, and Dubai fire officials said the flames were extinguished in just two hours.

Officials cordoned off the area near the building, keeping people about a block away from danger.

The fire was the second massive blaze at the tower in just over two years: Flames swallowed the building in February 2015, but again no one was injured.

Fire engineers said that that fire was likely accelerated by the exterior cladding – or siding – which was replaced last year, CBS News correspondent Jonathan Vigliotti reports. However, it remained unclear what caused the most recent blaze.

30,000 buildings in the United Arab Emirates are believed to have flammable siding. Earlier this year, Dubai passed a law requiring all flammable siding be replaced.
