Iraq investigates as Iran-backed militias blamed for Saudi pipeline attack
Saudi Arabia shuts down its key alternative oil export route after drone strikes from Iraqi territory; Baghdad dismisses officials and vows investigation amid broader regional pressure.
Iraq's government moved quickly Saturday to contain fallout after local Iran-backed militias were accused of launching drone strikes on Saudi Arabia's East-West pipeline. The attacks prompted Saudi Arabia to shut down the cross-country pipeline as a precautionary measure on Friday. Though an umbrella group of Iran-backed militias denied involvement while praising the Houthis' battlefield gains, Iraq confirmed the attacks originated from its territory and dismissed two senior officials, including Maysan province's military commander. Iraqi Prime Minister Ali al-Zaidi ordered investigations into operations in Maysan province, which borders Iran.
The pipeline closure carries significant weight: Saudi Arabia had doubled oil exports through this Red Sea route to over 5 million barrels per day by June, creating a workaround after the U.S.-Iran conflict disrupted the Strait of Hormuz. Regional officials have told the AP that Houthi rebels and Iraqi militias recently coordinated attacks on Saudi oil facilities—a pattern that prompted U.S. and Saudi airstrikes on Iranian-backed militias in Iraq in July.
Iraq faces compounding pressure. The government has set a September 30 deadline for non-state militias to disarm, but several powerful groups have refused. Simultaneously, Iran-backed Houthi rebels continue advancing across Yemen's west coast and seized an island in the Bab el-Mandeb Strait Friday, through which roughly 12% of global trade passes. Iraq also closed two border crossings with Iran on Saturday—Shalamcheh and Chazabeh—in a move possibly linked to the investigation.
President Trump said Iran was "probably" responsible for the pipeline attack while downplaying concerns. He stated his administration has held discussions with the Houthis, including at least one round in May 2025, claiming the group prefers not to fight the U.S. and is allowing most ships through. Saudi Arabia, notably, signaled restraint, saying it would not retaliate to give Iraq "an opportunity to take the necessary measures."
How could this affect you
Traced by who's actually in the path of this — not everyone is.
Direct
Energy traders and oil importers
Closure of the East-West pipeline removes Saudi Arabia's primary workaround to Strait of Hormuz disruption. If the pipeline remains shut or is targeted again, global oil supply tightens and prices rise. The pipeline accounts for over 5 million barrels per day of Saudi exports.
Likely
Shipping companies and global commerce
Houthis have seized territory in the Bab el-Mandeb Strait and demonstrated coordination with Iraqi militias on Saudi targets. If this coordination intensifies and targeting spreads to commercial shipping, roughly 12% of global trade flowing through the strait faces disruption.
Likely
U.S. strategic interests in the Middle East
The pipeline attack signals Iraq cannot or will not fully control Iran-backed militias before the September 30 disarm deadline. This weakens Iraq as a counterbalance to Iranian influence and could trigger further U.S. airstrikes, escalating the regional conflict.
Likely
Iraqi government legitimacy
Dismissing officials and launching investigations may placate Saudi Arabia and the U.S. short-term, but if militias refuse to disarm by September 30 and strikes continue, Iraq's credibility as a sovereign state controlling its territory erodes, potentially inviting more external military action.
