Houthis had targeted the Abha and Jizan airports, Khamis Mushait military base and other sensitive targets in Saudi Arabia with rockets and drones, according to the spokesperson.
In September 2019, drones were used to attack the state-owned Saudi Aramco oil processing facilities at Abqaiq and Khurais in eastern Saudi Arabia.
The Houthi movement in Yemen claimed responsibility, tying it to events surrounding the Saudi Arabian 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 attack caused large fires at the processing facility, which, according to the Saudi regime's Interior Ministry, were put out several hours later. Both facilities were shut down for repairs, cutting Saudi's oil production by about half – representing about 5% of global oil production – and causing some destabilization of global financial markets.
