The Pentagon has once again raised its count of U.S. troops killed and wounded in operations tied to the U.S. war on Iran. The Pentagon quietly updated the figures without a public announcement on Friday. The Defense Casualty Analysis System website now lists 21 service members killed, up from 18, and 865 wounded, 98 more than in August.

This comes as 74 Democrats in Congress are pushing the Pentagon for answers about U.S. airstrikes in Iran that killed civilians. They’re focusing on a September strike on a wedding in Iran that killed five people, three adults and two children, and injured about 70 others. In a letter to Defense Secretary Pete Hegseth, the Democrats wrote, “We are deeply alarmed by the continued pattern of civilian casualties resulting from U.S. operations in the war in Iran, and the apparent lack of action and accountability from the Department. Acknowledging such incidents, accepting responsibility, and learning from them makes our forces stronger, more effective, and an example to the world. When we fail to do so, it has the exact opposite effect.”
