UAE finds Houthi attack on Abu Dhabi used ballistic missiles, cruise missiles, drones: report
The same weapons were used in separate attacks the Houthis conducted on Saudi Arabia on Monday night, the Wall Street Journal reported people who had been briefed on the Emirati investigation as saying.
Three people were killed and six others injured in the attack on an oil storage facility in the UAE capital, which the Houthis claimed responsibility for.
The attack follows the Houthis' seizure of a UAE-flagged ship off the coast of Hodeidah, Yemen's main port, on 3 January.
The UAE has asked the US to reinstate its designation of the Houthis as a terrorist organisation in response to the attacks, according to reports.
Abu Dhabi is a member of the Saudi-led coalition fighting the Houthi rebels in support of the Yemeni government.
Forces allied with the Yemeni government and the Houthis have fought for control of the country for more than seven years.
The war created "the world's worst humanitarian crisis", the United Nations has previously said.
The Saudi-led coalition bombed targets near the Yemeni capital Sanaa following Monday's attacks.
