Saudi and US Forces Launch Joint Airstrikes on Iran-Backed Militias in Iraq

U.S. and Saudi forces launched joint airstrikes targeting Iran-backed militia compounds in eastern Iraq on July 29, 2026, marking a rare direct military offensive that killed 20 fighters and rattled global energy markets amid escalating cross-border drone and missile attacks.

Fighter jets from the United States and Saudi Arabia conducted a coordinated military offensive late Tuesday, July 29, 2026, striking terrorist logistics and weapons sites across eastern Iraq. The operation shatters a long-standing regional precedent in which Riyadh typically relied on Washington to project power against Iranian interests while avoiding overt kinetic engagement that could invite retaliation on domestic energy infrastructure.

Popular Mobilization Forces Report Casualties and Damage

The Popular Mobilization Forces (PMF), a coalition of primarily Shiite, Iran-backed armed groups officially under the command of the Iraqi military, confirmed that at least 20 fighters were killed and 32 others wounded in the overnight raids. The paramilitary organization stated that its headquarters in Baghdad and six other locations across several parts of Iraq were hit during the operation.

Iraqi Prime Minister Ali al-Zaidi responded to the military action by calling an emergency meeting of the country’s National Security Council on Wednesday to discuss the strikes. The Iraqi government forcefully condemned the joint operation, with Baghdad labeling them a "dangerous escalation" and a direct violation of state sovereignty.

“U.S. and Saudi fighter aircraft struck multiple terrorist logistics and weapons sites across eastern Iraq in a strong response to over 30 IRGC-directed aerial drone attacks in the last 72 hours.”

Regional Crossfire Draws Jordan and Saudi Energy Sites

The joint offensive arrived in direct retaliation after Iran fired ballistic missiles at a strategic U.S. military base in Jordan. While U.S. Central Command confirmed that inbound Iranian missiles were successfully intercepted, the audacity of the strike demonstrated a willingness by Tehran to bypass proxies and launch direct assaults on American personnel.

Simultaneously, Saudi Arabia responded to a streak of drone strikes from Iran-backed militias targeting Aramco’s Abqaiq oil processing facility—the world’s largest crude stabilization plant, which boasts a capacity of approximately 7 million barrels of crude oil per day. Houthi rebels also attacked an Aramco oil company refinery in Jazan over the weekend, forcing a temporary shutdown, just days after a Saudi oil tanker was attacked in the Bab el-Mandeb Strait.

The Saudi Ministry of Defense acknowledged the joint operations in a social media statement, warning that "the Kingdom emphasizes that it does not seek escalation but will respond to any aggression it faces."

Strait of Hormuz Deadlock and Global Energy Impact

The renewed fighting flared at the conclusion of a lull in U.S. attacks, interrupting back-channel negotiations over the strategic Strait of Hormuz, through which roughly 20% of the world’s traded oil normally flows. Tensions surged after Iran rejected a proposal from Oman to jointly manage shipping traffic by dividing the waterway into two distinct routes.

Kazem Gharibabadi, deputy foreign minister for legal and international affairs of Iran, stated that Tehran rejected the Omani plan because it failed to address national concerns, offering instead a counterproposal. Gharibabadi added that Iran’s policy is for the critical waterway "never to return to its prewar situation."

The immediate consequence of the regional escalation was a measurable shock to commodity markets. Brent crude surged by 3.44 percent, resulting in a price of USD 81.46 per barrel as traders priced in potential supply disruptions across the Persian Gulf.

Broader Strategic Repercussions and Stances

Foreign Minister Seyed Abbas Araghchi underscored Tehran’s defiant posture in a post on social platform X earlier this month, emphasizing that "Our defense doctrine is clear: eye for an eye." Araghchi warned that any aggression against Iranian infrastructure would compel a powerful response and that contributors to such actions would be treated as legitimate targets.

As the Trump administration evaluates its next military options, diplomats warn that the window for de-escalation is narrowing rapidly. With Saudi Arabia actively participating in air strikes across a neighboring state, the multi-month conflict has transformed from a localized proxy campaign into an overt regional confrontation.
