“Oil prices have spiked higher this morning after Iran-backed Houthi rebels unleashed a coordinated attack on Saudi Arabia oil facilities and military bases,” Axi chief global markets strategist Stephen Innes said in a note.

Yemeni Houthi forces fired drones and missiles to target the Saudi Arabian oil industry on Sunday, including Saudi Aramco’s facility at Ras Tanura, with Riyadh labeling the attack as a failed assault on global energy security after the drones and missiles were intercepted.

Ras Tanura is capable of exporting roughly 6.5 million barrels a day, and as such is critical to the Saudi oil industry.

The latest move by Iran-backed Houthi is the latest in a series of attacks on Saudi Arabia and follows a recent rise in Middle Eastern tensions. The U.S., under the Joe Biden administration, also carried out airstrikes in Syria in January on sites it said were related to Iran-backed groups.

“It’s a perfect mix of bullish news at the moment … it does seem that these attacks are picking up in frequency, so the market may need to price in some risk premium,” ING Bank NV head of commodities strategy Warren Patterson told Bloomberg.

Both Brent and WTI futures rose for a fourth consecutive session and were boosted by the Organization of the Petroleum Exporting Countries and allies (OPEC+) decision, made during the previous week, to keep production cuts largely unchanged in April.

Saudi Energy Minister Prince Abdulaziz bin Salman urged caution despite fast-rising crude prices, however. Elsewhere, Indian oil minister Dharmendra Pradhan warned higher prices could threaten the consumption-led recovery in some countries.
