DUBAI, United Arab Emirates: A fire struck downtown Abu Dhabi early Wednesday, with authorities initially blaming a gas cylinder for an explosion caught on camera in social media.

The blast struck Hamdan Street in the capital of the United Arab Emirates as it hosts the FIFA Club World Cup. Journalists from Brazil covering a match with Sociedade Esportiva Palmeiras reported on the blast.

The state-run WAM news agency described the fire as coming from “a gas cylinder explosion.” Some footage showed what appeared to be a fireball on the roof of a building as emergency service vehicles could be seen on the street.

The images seen in videos corresponded to known features in Abu Dhabi. Authorities initially said by Twitter there were no injuries, but did not include that detail in a later update.

“The process of cooling and limiting the damage caused by the fire is underway,” the WAM report said.

The incident comes after Yemen’s Houthi rebels have launched several attacks targeting Abu Dhabi, including a recent attack that killed three people and wounded six.
