Why France Is Sending Troops to Protect Saudi Arabia’s Yanbu Oil Port

Most of Saudi Arabia’s oil comes out of the ground in the Eastern Province, close to the Gulf. For decades most of it left the country the obvious way: by tanker from Gulf terminals such as Ras Tanura, then out through the Strait of Hormuz, a channel that Iran borders on its northern side. In 2025, according to the International Energy Agency, about 15 million barrels a day of crude and 5 million barrels a day of oil products passed through it.

Yanbu is the answer to the obvious question: what happens if Hormuz closes? It sits on the Red Sea coast, about 1,200 km west of the oil fields. The old town, Yanbu al-Bahr, was for centuries the sea gate for pilgrims and trade heading to Medina. The modern industrial city, Yanbu al-Sinaiyah, was built from the late 1970s under the Royal Commission for Jubail and Yanbu. Today it holds crude export terminals, storage and several large refineries, including the Aramco joint ventures SAMREF and YASREF.

The connection between the two coasts is the East-West Pipeline, also called Petroline. As long as it runs, Saudi oil can reach customers in Europe and Asia without a single tanker going near Hormuz. That is why Yanbu’s importance rises and falls with the danger in the Gulf. In a normal year it is useful. In 2026 it became essential.

The East-West Crude Oil Pipeline was commissioned in 1981, a year into the Iran–Iraq war, when both sides were already attacking oil facilities and the “tanker war” in the Gulf was about to begin. It runs 1,201 km from Abqaiq, Aramco’s giant processing centre near the Gulf, to Yanbu, pushed along by 13 pumping stations. The system has two large lines: one built for crude, and a second, originally for natural gas liquids, that Aramco has moved over to crude. By March 2026 the IEA was describing it as a 7 million barrels a day pipeline; in 2018 its stated capacity was 5 million.

The design logic has never changed: if Hormuz is blocked, pump the oil the other way. What the pipeline cannot do is make itself safe. In May 2019, Houthi drones hit pumping stations near Afif and briefly shut it down. In September 2019, the attack on Abqaiq and Khurais knocked out about half of Saudi output for days. Both showed that a bypass route is only as strong as its weakest pumping station.

For the full engineering and operational history of the line, see our Saudi East-West Pipeline timeline. This page focuses on what happened at its western end in 2026, and why France got involved.

France was among the first countries to recognise the Kingdom of Saudi Arabia, in 1932, and had kept a consulate in Jeddah since 1839. The security relationship came later, and it was built around exactly the things Macron is now sending: air defence and naval power.

Air defence, 1970s–1980s. French industry built the Shahine short-range air-defence system, a version of the Crotale missile developed for Saudi Arabia, which entered Saudi service around 1980.

The Grand Mosque, 1979. When armed militants seized the Grand Mosque in Mecca in November 1979, a small team from France’s GIGN gendarmerie unit advised Saudi forces on retaking it. It remains one of the most sensitive episodes in the relationship.

The navy, 1980 and 1994. Under the Sawari I programme, signed in 1980, France supplied four frigates and two replenishment tankers to the Royal Saudi Navy’s western fleet, which is based on the Red Sea. Sawari II, signed in 1994, added three Al Riyadh-class air-defence frigates delivered in the early 2000s. In other words, France has been equipping the Saudi Red Sea fleet for more than 40 years.

Macron’s era. Macron made a surprise stop in Riyadh in November 2017, days after a Houthi missile was fired at the capital. Crown Prince Mohammed bin Salman came to Paris in April 2018, when Saudi and French firms signed about $18 billion in deals. Macron met him in Jeddah in December 2021, and hosted him at the Elysée in July 2022.

December 2024: the strategic partnership. During Macron’s state visit to Saudi Arabia on 2–4 December 2024, the two countries announced a formal strategic partnership covering defence, energy, culture, investment and mobility.

24 August 2026: the council. Mohammed bin Salman returned to the Elysée on 24 August 2026. The two leaders chaired the first meeting of a new Saudi-French Strategic Partnership Council, and, in the words of their joint statement, “adopted a declaration strengthening their defence cooperation, including in the field of armaments and training”. The same statement called for Hormuz to return to “its normal state as it was before February 28, 2026”. One month later, French soldiers were promised to Yanbu.

France is not arriving in the region from nowhere. It keeps about 1,500 personnel in Djibouti, at the southern mouth of the Red Sea, and about 750 in the United Arab Emirates, where it opened a permanent base in Abu Dhabi in 2009, according to figures cited by Arab News.

At sea, French warships were already shooting down drones in the Red Sea before the EU acted. The frigate Languedoc destroyed two drones heading towards it in December 2023. On 19 February 2024, the EU launched Operation ASPIDES (Greek for “shields”) to protect merchant ships from Houthi attacks. France has been one of its main contributors, and describes the mission as purely defensive: escorting and protecting ships, not striking Yemen.

That is the model France is now applying on land. ASPIDES shields ships; the Yanbu mission is meant to shield a port. In both cases Paris draws a line between defending against missiles and drones and attacking the people who launch them.

28 February 2026: war. The US-Israeli war with Iran began on 28 February. Within days, Iran had effectively shut the Strait of Hormuz. The IEA’s March report said flows through the chokepoint were running at less than 10% of pre-crisis levels.

March: the pivot west. Aramco began pushing as much crude as it could through the East-West Pipeline. Before the war, the IEA said, the line was carrying only about 2–2.5 million barrels a day, much of it for Red Sea refineries and power plants. On 9 March 2026, Saudi exports from western ports hit a record 5.9 million barrels a day, against an average of 1.7 million in 2025.

April: the first hit. On 9 April, an Iranian drone attack cut the pipeline’s throughput by about 700,000 barrels a day. Saudi Arabia said full capacity was restored on 12 April.

July: the Red Sea front opens. Saudi Arabia and the Houthis had kept an informal truce for years. It broke on 13 July 2026, when Saudi Arabia struck the runway at Sanaa airport to stop an Iranian aircraft carrying Houthi officials from landing. The Houthis fired missiles and drones at southern Saudi Arabia, and on 20 July they declared a naval blockade of Saudi Arabia, threatening ships carrying Saudi exports through Bab el-Mandeb. They also claimed attacks on Aramco sites in Jizan and Yanbu.

The result was a trap. Saudi Arabia had moved its exports west to escape Iran’s grip on Hormuz, only to find Iran’s Yemeni allies threatening the western route too.

10–11 September: drones from Iraq. Several drones struck pumping stations on the East-West Pipeline in the Riyadh and Medina regions. The Saudi Press Agency said they came from Iraq. Satellite images showed black smoke along the route between Medina and Mahd al-Dhahab, and several people were injured. The energy ministry shut the pipeline “as a precautionary measure”. (Reuters later dated the full shutdown to 13 September; reports differ by two days.) At the time the line was moving roughly 4 million barrels a day to Yanbu, around 4% of world supply. Brent crude went back above $100 a barrel.

12–13 September: Iraq responds. Saudi Arabia chose not to retaliate after Iraq’s prime minister asked for time to act. Iraq said its investigation traced the launches to Maysan province and dismissed a military commander there.

16 September: first Houthi claim on Yanbu. The Houthis said they had struck an Aramco facility in Yanbu with “dozens of ballistic missiles and attack drones”, causing a large fire. They gave no evidence, and neither Riyadh nor Aramco confirmed any damage.

19 September: second claim. The Houthis claimed strikes on Riyadh and again on an Aramco facility in Yanbu. Reuters witnesses reported explosions and smoke near Riyadh airport after an air-raid warning. There was no Saudi confirmation of damage at Yanbu.

22 September: two things happen on one day. Saudi Arabia restarted the East-West Pipeline, pumping at a low rate. One tanker was due to load at Yanbu that day, bound for China. Sources told Reuters that reaching 40% of capacity would take a couple of days and a full return six to eight weeks. The same day, a French diplomatic source said: “France is ready to contribute to securing Saudi energy infrastructure in Yanbu and along the East-West Pipeline, within the framework of a strictly defensive approach.” It added that this “in no way” meant taking part in the conflict with the Houthis.

24 September: Macron on television. In a prime-time interview on TF1 and France 2, Macron said: “We are going to send military resources, that is to say, soldiers, radar systems and defence systems, to protect this site — not to get us involved in any conflicts, but to protect this site.” He tied it directly to prices at home: the Middle East war had pushed French fuel prices to historic highs, and he wanted to keep energy flowing as winter approaches.

24–25 September: the Houthis answer. Within hours, the Houthis claimed new missile and drone attacks on Riyadh and Aramco facilities in Yanbu. The Saudi-led coalition said it had intercepted six ballistic missiles aimed at Taif and Yanbu, and civil-defence alerts sounded in Mecca, Yanbu, Taif, Jeddah and Tabuk. This time Saudi Arabia did confirm that Yanbu had been targeted, though it reported interceptions, not damage.

The United States is still Saudi Arabia’s main security partner, and is itself at war with Iran. A few hundred or even a few thousand French personnel at one port do not change that. What the Yanbu mission does show is a pattern Riyadh has pursued for years: more than one partner. France’s foreign ministry describes Saudi Arabia’s effort to diversify its defence partnerships and build its own defence industry, with French cooperation focused on training and capability development.

Yasmine Farouk, who directs the Gulf and Arabian Peninsula project at the International Crisis Group, told Arab News that European governments are not against deploying to the Gulf, but that their forces are limited. France’s move, she said, “might help operationalize that European will to help the Kingdom”, and fits a wider French ambition to be a Gulf power through defence ties with the UAE, Kuwait and Qatar.

So the change is less “America out, France in” and more one dominant partner becoming several, each covering a piece of the map.

For most of the oil age, energy security meant one question: how much can you produce? In 2026 the question became: can you move it? Pipelines, pumping stations, terminals and tanker lanes are now military targets, and radars and interceptors have become part of the export system.

Yanbu shows the paradox clearly. The East-West Pipeline was built so that one chokepoint could not strangle Saudi exports. When that chokepoint closed, the bypass carried the load, and became the new target. A route designed to avoid danger became indispensable, and being indispensable made it vulnerable. France’s mission is a bet that defending one node of that network is worth the political risk of standing next to it.
