Iraqi Prime Minister Ali al-Zaidi, who also serves as Commander-in-Chief of the armed forces, on Saturday, 12 September approved Iran's request to conduct a joint investigation aimed at identifying drone launch platforms near the Iraq-Iran border. The confirmation came from Sabah al-Numan, Spokesman for the Commander-in-Chief of Iraqi forces, amid a sharp escalation in border security tensions following drone attacks on Saudi Arabia traced back to Iraqi territory.

Background to the Decision

The approval followed confirmation by Iraqi authorities that recent drone strikes targeting Saudi Arabia were launched from a site within Maysan province in southern Iraq. Saudi Arabia's Foreign Ministry stated on Friday that its East-West Pipeline was struck by several drones launched from Iraqi soil, resulting in injuries and infrastructure damage. Notably, Riyadh said it had refrained from retaliating at this stage, reportedly at the request of the Iraqi Prime Minister.

Military and Security Shakeup

Earlier on Saturday, al-Zaidi dismissed both the Maysan Operations Commander and the Maysan Police Commander, signalling a direct accountability response. He also ordered the formation of a special investigative council to probe the security lapse, according to separate statements issued by al-Numan. This is one of the most significant command-level reshuffles in Iraq's southern military structure in recent years.

Border Crossings Under Lockdown

Iraqi security forces have launched administrative and security reorganisation operations at several border crossings, necessitating temporary closures to investigate potential security breaches. The Security Media Cell, affiliated with the Iraqi Joint Operations Command, said that legal measures have been taken and intelligence, investigative, and audit efforts intensified to determine the circumstances surrounding violations at these crossings.

However, the Zurbatiyah and al-Munthiriya border crossings with Iran — located in Iraq's Wasit and Diyala provinces respectively — remain open to passenger traffic. An Iraqi security source, speaking on condition of anonymity, indicated that inspection and screening procedures are underway at the closed crossings and are expected to conclude quickly.

Why This Matters

The episode underscores a persistent vulnerability: Iraq's southern border zones have long been exploited by armed groups for cross-border operations, and the confirmation that Saudi-targeting drones were launched from Iraqi soil escalates the diplomatic stakes considerably. Saudi Arabia's stated restraint — conditional on Iraqi action — places Baghdad under intense pressure to deliver credible investigative results.

This comes amid broader regional tensions involving drone and missile threats across the Gulf. The joint probe with Iran is notable because it signals a willingness by both governments to cooperate on a matter that could implicate Iran-aligned armed factions operating on Iraqi soil. Whether this cooperation yields actionable outcomes or remains largely procedural will be closely watched by Gulf states, Western allies, and regional security analysts alike.
