Abqaiq–Khurais attack

On 14 September 2019, drones were used to attack oil processing facilities at Abqaiq (Arabic: بقيق, romanized: Buqaiq) and Khurais (خريص) in eastern Saudi Arabia. The facilities were operated by Saudi Aramco, the country's state-owned oil company. The Houthi movement in Yemen claimed responsibility, tying it to events surrounding the Saudi intervention in the Yemeni Civil War and stating they used ten drones in the attack launched from Yemen, south of the facilities. Saudi Arabian officials said that many more drones and cruise missiles were used for the attack and originated from the north and east, and that they were of Iranian manufacture. The United States and Saudi Arabia have stated that Iran was behind the attack while France, Germany, and the United Kingdom jointly stated Iran bears responsibility for it. Iran has denied any involvement. The situation exacerbated the 2019 Persian Gulf crisis.

The attack caused large fires at the processing facility, which were put out several hours later, according to Saudi Arabia's Ministry of Interior. Both facilities were shut down for repairs, cutting Saudi Arabia's oil production by about half – representing about five percent of global oil production – and causing some destabilization of global financial markets. The Ministry of Energy said that the country would tap into its oil reserves to maintain export levels until the facilities return to full capacity by the end of September.
