Civil defense teams in the UAE capital of Abu Dhabi said they put out a fire caused by a gas cylinder explosion early on Wednesday, while the U.S. embassy issued a warning of "reports of a possible missile or drone strike", Reuters reports.
The United Arab Emirates has in recent weeks faced mostly foiled attacks by Yemen's Houthi movement. It was not clear if the reports cited by the embassy were linked to the fire.
The recent attacks on the regional hub, which prizes its reputation as a safe business and tourism destination, have caused some anxiety among residents. The civil defense authority on Wednesday asked the public to follow only official news sources and to avoid spreading rumors.
UAE authorities did not immediately respond to a request for comment and the U.S. embassy could not immediately be reached. Houthi-run media have not claimed any new attack.
Abu Dhabi civil defense said it received a report of a fire at 12:09 a.m. (2009 GMT) caused by a gas cylinder explosion in a building in a central residential area. It said there were no casualties.
"Specialized teams extinguished the fire, evacuated the building as a precaution and controlled the situation," the civil defense authority said in a statement on state media.
