Washington — The Pentagon has formally acknowledged that U.S. military operations killed more than 150 innocent civilians and injured over 240 people in 2025, with three airstrikes in Yemen accounting for every casualty the department confirmed. The newly released tally, which did not include any deaths from airstrikes on boats in the Caribbean Sea and Pacific Ocean, comes as the Pentagon prosecutes a far broader military operation against Iran that began this year. It also follows cuts to some offices dedicated to mitigating civilian casualties during the tenure of Defense Secretary Pete Hegseth, who has vowed to focus on "lethality" rather than "tepid legality."A report submitted to Congress late Monday and obtained by CBS News shows military strikes during the campaign against Yemen's Houthi militia group, named Operation Rough Rider, killed 153 civilians and injured another 243 last year. From March to May 2025, the U.S. military bombed targets in Yemen related to the Iran-backed Houthis to prevent the group from attacking commercial ships in the Red Sea. The report found that "more likely than not," five civilians were killed on April 6 near the Yemeni capital of Sanaa, 80 were killed on April 17 near Ras Isa Port and another 68 were killed on April 28 near Saada. The military did not conduct site visits or interviews to make the assessments, but it relied on U.S. intelligence, imagery and public reporting, according to the report. NBC News and The Washington Post were first to report details on the assessments. Airwars, an organization that tracks civilian harm in conflicts, reported last year at least 258 civilians may have been killed in Operation Rough Rider. The report from the Pentagon has at least 153, but notes that as of earlier this year, there were 15 other incidents in Yemen the military was assessing in response to reports received through nongovernmental organizations.
