Saudi Arabia announced on Saturday that it has halted operations on its 1,200‑kilometre East‑West oil pipeline after a drone strike it traced to Iraqi territory, accusing Iran‑backed militias of the attack. The shutdown cuts a vital conduit that the kingdom has relied on to move crude around the Strait of Hormuz since the start of the war on Iran, and it comes as Houthi forces in Yemen tighten their grip on Red Sea shipping lanes.

Drone strike and immediate response

According to a statement relayed by Reuters, Saudi officials said the pipeline was hit by unmanned aerial vehicles launched from the Maysan province of Iraq, prompting an immediate shutdown to protect the infrastructure. The Saudi Ministry of Energy confirmed the closure, describing the strike as a "significant security breach".

"We have shut the East-West pipeline after it was hit by drones launched from Iraqi territory," a Saudi spokesperson told reporters.
The Guardian and ABC11 News both reported that the kingdom blamed Iran‑aligned militias operating in Iraq, while Al Jazeera noted that Iraq’s prime minister, Ali al‑Zaidi, ordered an investigation and dismissed the local commander responsible for the area.

Strategic role of the East‑West pipeline

The East‑West line, which runs from the oil‑rich fields in the eastern province of Khurais to the Red Sea port of Yanbu, can transport up to 5 million barrels of crude per day, according to multiple sources including France 24 and Bloomberg. Since the escalation of hostilities with Iran, Saudi Arabia has increased reliance on the pipeline to bypass the narrow and contested Strait of Hormuz, a chokepoint that Iran has threatened to close.

The New York Times highlighted that the pipeline serves as a “lifeline” for the kingdom’s export capacity, allowing Saudi oil to reach Asian markets without transiting the Persian Gulf. The shutdown therefore forces exporters to reroute shipments through longer, costlier paths, potentially raising global oil and gas prices.

Broader regional flare‑up

Simultaneously, the Iran‑aligned Houthi movement in Yemen has seized several strategic points along the Red Sea coast, including the Bab al‑Mandeb strait, according to NPR and EA WorldView. The Houthis’ advances have prompted the United States to reassess its naval posture in the region, as reported by The Washington Post, while Saudi Arabia has warned that the combined pressure on both the Gulf and Red Sea routes could destabilise global energy markets.

Iran, meanwhile, has leveraged its influence over the two key shipping corridors – the Strait of Hormuz and the Red Sea – to gain diplomatic leverage, a development outlined by The New York Times. Tehran’s allies now hold sway over “two of the world’s most important oil shipping routes,” the paper wrote, positioning Iran for a potential bargaining chip in any future negotiations with the United States.

Economic implications and next steps

Energy analysts cited by DW.com and NewsCord warned that the pipeline outage could lift Brent crude prices by several dollars per barrel and push global gas prices higher, especially as other supply lines face disruptions. The shutdown also underscores the vulnerability of Saudi export infrastructure to low‑cost, asymmetric attacks.

Iraq has begun an internal probe, closing three border crossings to Iran as a precaution, according to Al Jazeera. The investigation aims to identify the specific militia group responsible and to prevent further incursions, a move that reflects Baghdad’s delicate balancing act between curbing Iranian influence and maintaining internal stability.

International observers, including the International Energy Agency, are monitoring the situation closely. In the meantime, Saudi Arabia has not indicated a timeline for reopening the East‑West pipeline, leaving markets to grapple with the uncertainty while regional powers vie for influence over the world’s oil arteries.
