Rumors flew in Dubai Sunday night, as an eerie fog made it appear as if the famed Burj Khalifa were on fire.

Many locals posted pictures on social media, wondering what was happening at the world's tallest tower. Some residents claimed that ambulances and emergency services were rushing to the tower itself.

The video below circulated fast, with a man saying:"Fire, Fire."

However, the police and Burj Khalifa staff rebuffed the rumors.

The police took to Twitter to clear the air, saying that “It’s that time of year the clouds gather around Burj Khalifa and trick us. It’s just a fog, our beloved Burj Khalifa is safe."

A source in Civil Defense told Emirates 24/7 that when the temperature of the humidity outside the building reaches a certain level in comparison to the temperature inside the tower, clouds form around the tower. It is perfectly safe and can occur at this time of year.
