Iraq is grappling with controversy over the role of Iran-backed militias following the departure of US forces, including an incident in which Popular Mobilization Forces members were photographed driving over an American flag. Prime Minister Ali al Zaidi is pushing to bring militia weapons under state control by June 2027, with several factions reportedly agreeing to disarm while others continue to resist.

Iraq faces mounting pressure to rein in the militias while balancing tensions with neighboring countries, the US, and Iran. The Kurdistan Region of northern Iraq has come under nearly 1,000 drone and missile attacks by Iran and its proxies since late February, underscoring the growing threat posed by Tehran’s network of militias.

The United States has intensified pressure on Iranian-backed militias in Iraq, offering multimillion-dollar rewards for information on additional key leaders linked to attacks on US personnel and facilities. The latest rewards target figures from three groups: Kataib Hezbollah, Kataib Sayyid al Shuhada, and Harakat Ansar Allah al Awfiya.

The US Treasury Department announced the designation of seven high-level members of Iran-backed Iraqi militias as Specially Designated Global Terrorists on April 17. Their organizations are previously US-designated terror groups that, operating under front groups, have conducted numerous attacks on the US presence in Iraq since the start of the war with Iran on February 28.

The Islamic Resistance in Iraq (IRI), a coalition of Iran-backed Shiite militias, claimed over a dozen drone attacks against “enemy bases in Iraq and the region” and issued statements of support for the Tehran regime in retaliation for US and Israeli strikes on Iran. The groups are also responding to unclaimed airstrikes on Iraq that have reportedly killed at least six people, including four confirmed Iraqi militiamen.

Five Iranian Kurdish opposition groups have announced a coalition aimed at opposing Iran’s regime. The alliance, unveiled at a joint press conference on February 22, includes the PDKI, PJAK, PAK, Komala, and the Khabat Organization. The move comes amid heightened US-Iran tensions and renewed threats from the Iranian-backed Iraqi militia Kataib Hezbollah, which warned the Kurdistan Region against cooperating with “foreign forces.”

Kataib Hezbollah, an Iraqi Shiite militia, warned the United States that if Washington launched a war with Iran, the group would attack American bases in the region. The threat comes amid rising tension between Washington and Tehran as the Islamic Republic continues a brutal crackdown on demonstrations that began nearly three weeks ago.

Iranian-backed militias in Iraq are reportedly considering an initiative to disarm and place their weapons under government control. The militias, part of Iraq’s Popular Mobilization Forces (PMF), have been incorporated as independent units within Iraq’s security forces since 2016. Kataib Hezbollah, one of the most powerful of militias, has rejected disarmament, while the US lauded the potential development.

On September 17, the US State Department designated four Iran-backed Iraqi militias as Foreign Terrorist Organizations (FTOs). These groups, previously listed as Specially Designated Global Terrorists (SDGTs), have received support from the regime in Tehran and attacked US forces and interests in Iraq and across the Middle East.

Iraqi and American officials announced that the US-led counter-Islamic State operation in Iraq began its transition to a bilateral security agreement. US forces have begun moving from Iraqi bases as part of the first phase of the shift, which will end “the coalition’s military mission” in the country.

Kataib Hezbollah, an Iran-backed militia, was involved in a deadly shooting at Iraq’s Ministry of Agriculture on July 27. Despite the support for Iran-backed militias from many Shiite politicians, Iraqi Prime Minister Mohammad Shia al Sudani announced the results of an investigation that found the militia responsible for the incident and recommended consequences.

Iranian-backed militias in Iraq have refrained from attacking Israel directly since the start of the war between Israel and Iran on June 13. However, there have been two unclaimed attacks on US interests in Iraq since Operation Rising Lion began, and the Iraqi groups have ramped up anti-Israeli and anti-American rhetoric, threatening US interests and mobilizing supporters through propaganda channels.

Kataib Imam Ali is the sixth Iran-backed Shiite militia in Iraq that has been listed by the US as a terrorist organization. The group’s secretary general was previously designated for his ties to Iran’s Islamic Revolutionary Guards Corps–Qods Force and its former commander, Qassem Soleimani.

On March 5, Iraqi National Security Advisor Qassem al Araji said that Baghdad is trying to locate kidnapped researcher Elizabeth Tsurkov, an Israeli and Russian citizen who was abducted in March 2023. Israeli officials have blamed Kataib Hezbollah for kidnapping Tsurkov, and her case has received increased attention in the last two months since the Trump administration entered office.

Falih al Fayyadh, the head of Iraq’s largely pro-Iranian Popular Mobilization Units (PMU), traveled to Beirut for the funeral of Hezbollah leader Hassan Nasrallah on February 23. Other senior members of pro-Iranian militias in Iraq also attended the funeral, and several militia leaders put out statements. Hezbollah-affiliated media claimed approximately 200,000 Iraqis came to Lebanon for the event, though this number is unverified.
