Pentagon Report Reveals Steep Civilian Toll in Trump's Yemen Campaign After Casualty Mitigation Office Dismantling

The Pentagon has formally acknowledged that U.S. military operations in Yemen last year killed 153 civilians and injured 243 others, marking the Trump administration's first public admission of significant noncombatant casualties in any conflict. The unclassified assessment, submitted to congressional defense committees late Monday, attributes all of the confirmed deaths to three airstrikes conducted in April 2025 against Houthi forces. The disclosure provides a stark official accounting of a campaign that had previously been shrouded in operational secrecy.[1]

The strikes were part of "Operation Rough Rider," a 53-day air and naval campaign authorized by President Donald Trump to degrade the Iran-backed Houthis' ability to attack commercial shipping in the Red Sea. U.S. forces struck more than 1,000 targets during the operation, which concluded in early May 2025 after the militant group agreed to halt its maritime attacks. According to the newly released report, the U.S. Central Command determined that three specific operations "more likely than not" resulted in civilian harm.[1][2]

The deadliest of the three incidents occurred on April 17, 2025, when a U.S. attack on the Ras Isa port in western Yemen killed 80 people and injured 171. Eleven days later, on April 28, another strike near Saada—which independent investigations previously identified as a migrant detention center—killed 68 civilians. A third strike on April 6 near the capital city of Sanaa left five dead. The Pentagon's review noted that the casualties stemming from the Sanaa incident occurred at a residential compound.[1]

The Yemen campaign was the first major U.S. military operation conducted after Defense Secretary Pete Hegseth dismantled the Pentagon's Civilian Harm Mitigation and Response program. Hegseth cut the office's personnel by roughly 90 percent shortly after taking office, arguing that the military needed to eliminate bureaucratic red tape and focus on "maximum lethality, not tepid legality." The timing of the cuts has drawn intense scrutiny to the operational safeguards in place during the Yemen strikes.[3]

Lawmakers and human rights advocates have seized on the report as evidence that the administration's policy shift directly endangered noncombatants. Sen. Jack Reed (D-RI), the top Democrat on the Senate Armed Services Committee, called the casualties the predictable result of a "poorly conceived" campaign. Reed demanded a "direct and honest reckoning" from Hegseth, arguing that the deliberate dismantling of civilian protection protocols has severely damaged the United States' moral standing and operational integrity.[5]

The Pentagon's assessment relied entirely on U.S. intelligence, aerial imagery, and open-source reporting rather than on-the-ground site visits or witness interviews. While military officials maintain that U.S. forces are "steadfastly committed to limiting harm to civilians" and possess a strong record of compliance with the laws of war, the report explicitly noted that "ex gratia" condolence payments were determined to be inappropriate for the victims of the Yemen incidents.[1][5]

Independent monitoring groups argue the official tally, while significant, still undercounts the true scale of the bloodshed. Airwars, a nongovernmental organization that tracks civilian harm in conflict zones, estimates that at least 224 to 258 civilians were killed during the U.S. operations in Yemen between March and May 2025. The organization's executive director questioned the administration's commitment to accountability, pointing out that the military's reliance on remote intelligence often fails to capture the full human cost of airstrikes.[1]

The Pentagon noted in its report that 15 additional incidents in Yemen remain under active review for possible civilian casualties, suggesting the final death toll from Operation Rough Rider could rise further. Furthermore, the report explicitly excluded casualties from controversial U.S. maritime strikes against suspected drug smuggling boats in the Caribbean and Pacific, which rights groups and independent monitors say have killed over 200 people since September 2025.[1][3][4]
