United Arab Emirates police said that drones may have caused the explosion of three oil tankers and a minor fire at an airport stretch in Abu Dhabi.
The Yemeni Houthi group, allied with Iran, later claimed responsibility for Monday's attack in southwestern Yemen, the United Arab Emirates.
Abu Dhabi Police said that three fuel tankers exploded in the Mussafah Industrial Area, near the storage facilities of the Adno Oil Company.

They said a fire also broke out at a construction site at Abu Dhabi International Airport - but added that it was "minor" and occurred in the main stretch of the airport which is still under construction.
The police said in a statement that preliminary investigations indicated the discovery of small flying objects, possibly belonging to drones, that fell in two areas, and may have caused the explosion and fire.
They said that there was no damage as a result of these incidents.

The Houthi military spokesman, Yahya Saree, said that the group launched an attack deep inside the Emirates, without providing further details.
The UAE has been fighting a war in Yemen since early 2015 and had a major role in the Saudi-led coalition, which launched attacks against the Houthi rebels after the organization overran the Yemeni capital and toppled the internationally backed government.
The Houthis have claimed responsibility for attacks on Abu Dhabi airport in the past, as well as the Barakah nuclear power plant in the UAE, which UAE officials have previously denied.
They also used bomb-laden drones to launch primitive and inaccurate attacks targeting Saudi Arabia and the UAE, and fired missiles at Saudi airports, oil facilities, and pipelines, in addition to using booby-trapped boats to launch attacks on major shipping routes.
Abu Dhabi is the seat of the government of the United Arab Emirates and directs the country's foreign policy.
Monday's attacks come as South Korean President Moon Jae-in is visiting the UAE.
The two countries are said to have reached a preliminary agreement worth around $3.5 billion (£2.5 billion) for the sale of South Korean medium-range surface-to-air missiles to the UAE.
The agreement was reportedly made during the president's meeting with UAE Prime Minister and Ruler of Dubai Sheikh Mohammed bin Rashid Al Maktoum on Sunday.
