In the early hours of Sunday, Iraqi elite counter-terrorism units and security forces conducted coordinated raids across Baghdad’s heavily fortified Green Zone and other districts, detaining at least 13 sitting members of parliament, former lawmakers, and senior government officials on corruption charges. The operations, executed under judicial warrants, were the largest anti-corruption sweep in recent years, with authorities reporting 47 arrests in total across Baghdad and other governorates, according to the state-run Iraqi News Agency. Among those held were Muthanna al-Samarrai, leader of the Sunni Azm alliance, and Ali Maarij, deputy oil minister for distribution, who had been sanctioned by Washington last month for allegedly facilitating Iranian oil smuggling.

Iraqi officials describe the crackdown as a direct implementation of Prime Minister Ali al-Zaidi’s commitment to combat graft, launched after confessions by Adnan al-Jumaili, a former deputy oil minister detained earlier over a $85 million embezzlement case. Iraq’s Federal Integrity Commission said the arrests resulted from “joint and complementary efforts” of the judiciary, executive, and legislature, and pledged transparent legal proceedings. Western diplomats in Baghdad view the timing as significant: the raids came days after a visit by US special envoy Tom Barak and ahead of Zaidi’s planned trip to Washington, where he seeks to recast bilateral ties from military partnership to economic and investment cooperation. A diplomat told Agence France-Presse the operation was “part of the Washington visit preparations,” intended to signal seriousness on reform.

The target list cuts across Iraq’s sectarian and political spectrum, including MPs from Sunni blocs such as Azm and Taqaddum, as well as figures linked to the Shia Coordination Framework and former prime minister Mohammed Shia al-Sudani’s Dawa-adjacent alliance. Security sources cited by regional media said the investigation extends to the smuggling of dollars and Iranian oil, implicating networks that allegedly financed armed factions close to Tehran. In Baghdad’s political salons, the arrests are interpreted as a move by Zaidi—an outsider backed by both Washington and a loose consensus of Iraqi parties—to consolidate authority and challenge entrenched patronage networks, though the full scope remains unclear as some suspects evaded capture, prompting a gunfire exchange and a manhunt that sealed the Green Zone for hours.

Analysts in Beirut and London note that while the crackdown is being framed as a legal campaign, its repercussions are inherently political, particularly as it unfolds during a fragile transition period following the stalled formation of Sudani’s government and amid heightened US-Iran tensions over the Strait of Hormuz. The operation could weaken Iran’s allies if the oil-smuggling networks are disrupted, but Tehran has not officially commented, and the reaction of armed groups remains uncertain. Iraqi judicial sources say the investigation is expanding, with additional arrest warrants expected as al-Jumaili’s testimony yields further names. The next concrete step will be Zaidi’s Washington visit, where he is expected to present the arrests as evidence of a functioning state capable of enforcing the rule of law.
