Washington — U.S. airstrikes targeting Iranian-backed Houthi rebels in Yemen last year killed more than 150 civilians, according to a Pentagon review of the attacks, which comes as concerns rise over civilian casualties during military campaigns under the Trump administration.
The unclassified assessment, obtained by the Associated Press, was sent to Congress as part of an annual report on civilian casualties and reported earlier by NBC News. A Pentagon official, who was not authorized to discuss the matter publicly and spoke on condition of anonymity, said the department will submit the report in the coming months but had nothing more to announce.
The Pentagon review focused on three airstrikes in April 2025 that were launched during the U.S. campaign against the Houthis. The militants were attacking commercial ships in the Red Sea, a crucial global trade route that leads to the Suez Canal and into the Mediterranean, as well as Israel.
Those strikes targeted hostile forces in or near Yemen’s rebel-held capital city of Sanaa as well as the Ras Isa port, the report said. A total of 153 civilians were killed and 243 were injured.
The strike on the port was the most deadly, killing 80 people and injuring 171 others. It sent massive fireballs billowing skyward and turned tanker trucks into burning wrecks. The Houthis aired graphic footage of the aftermath on their al-Masirah satellite news channel, showing corpses strewn about the port.
U.S. Central Command, which oversees military operations in the Middle East, said at the time that the “strike was not intended to harm the people of Yemen.”
“U.S. forces took action to eliminate this source of fuel for the Iran-backed Houthi terrorists and deprive them of illegal revenue that has funded Houthi efforts to terrorize the entire region for over 10 years,” said U.S. Central Command in its statement in April 2025.
The command determined that the three strikes “more likely than not” resulted in civilian harm, the review said. The information was based on U.S. intelligence sources, imagery and open-source reporting.
Civilian casualties from U.S. military operations have drawn concerns, including from lawmakers in Congress, after a U.S. missile struck an Iranian primary school in the opening days of this year’s war, killing up to 168 people. Defense Secretary Pete Hegseth is said to have slashed the size of an office focused on reducing civilian harm, the AP has reported.
The Pentagon assessment comes as the Houthis are carrying out a growing number of strikes against government forces in Yemen and oil facilities in neighboring Saudi Arabia, which supports the Yemeni government, and the kingdom’s shipping in the Red Sea.
Fears are growing that the renewed violence could reignite Yemen’s civil war following a 2022 truce and open a new front in the Middle East war.
