Axis Deepens: Saudis Say Iraqi Militias Attacked in Coordination With Houthis

Saudi Arabia is blaming Iran-backed Iraqi armed factions for coordinating a series of recent attacks on its eastern oil infrastructure alongside Yemen’s Houthi forces.

The cross-border strikes, launched from Iraqi territory, targeted the kingdom's primary crude oil hub.

Regional intelligence assessments indicate the joint operation was executed under the direct supervision of Iran’s Islamic Revolutionary Guard Corps (IRGC).

In response, Riyadh and Washington carried out retaliatory airstrikes on Wednesday against militant sites in Iraq.

Subsequent obituaries published by Iran-aligned media confirmed the deaths of IRGC operatives, Iraqi fighters, and at least one Houthi member.

Deepening Axis Integration

The coordinated assault highlights a structural shift within Tehran's proxy network.

Following the collapse of the Assad government in Syria and the systematic degradation of Hezbollah in Lebanon, Iraq is rapidly emerging as the primary operational hub for allied militant forces.

"There is now direct training and coordination between members of the Axis of Resistance themselves, not just between them and Iran," said Farea al-Muslimi, a research fellow at the Chatham House think tank's Middle East and North Africa program.

Operational ties between the Houthis and Iraqi factions, specifically the heavily armed Kataib Hezbollah, have accelerated significantly.

In 2024, Houthi leadership formalized a joint operations room in Baghdad, leading to their first shared military campaign targeting Israel later that year.

The Yemeni group now maintains a permanent physical footprint in the Iraqi capital, operating dedicated offices under its formal representative, Ahmed al-Sharafi, to liaise with local Shiite factions.

Border Vulnerabilities and Diplomatic Fallout

Iraq's expansive terrain and heavily porous 500-mile border with Saudi Arabia provide a strategic launchpad for covert regional strikes.

Security officials from Gulf states have previously traced hundreds of militant operations, including a March drone attack on the U.S. embassy in Riyadh and a strike on a UAE nuclear plant, back to Iraqi soil.

While the Houthis publicly claimed responsibility for the recent oil hub attacks to protest an alleged Saudi blockade on Yemen, Riyadh maintains it has imposed no such siege, citing the continuous arrival of maritime traffic at Houthi-controlled ports.

The immediate fallout from the U.S.-Saudi retaliatory bombings has severely fractured regional diplomacy.

Iraqi Prime Minister Ali al-Zaidi abruptly canceled a scheduled meeting on Thursday in Riyadh with Crown Prince Mohammed bin Salman.

Baghdad has announced an investigation into the cross-border strikes from its territory.

The incident directly challenges Zaidi's domestic agenda, which aims to consolidate state control over all armed factions by late September amidst intense resistance from militia leaders.
