America’s Iran War casualties crept higher even as the U.S. was in the final stages of declaring a second ceasefire with Iran this weekend.

The U.S. and Iran have agreed to a second ceasefire and the eventual reopening the Strait of Hormuz under a preliminary deal scheduled to take effect on Friday. “Iran has taken a major step toward final victory,” Mohammad Bagher Ghalibaf, the speaker of the Iranian Parliament, said on Monday, one of several Iranian leaders taking a victory lap after outlasting the Trump administration.

Trump’s war has already killed thousands of Iranian civilians — including more than 150, most of them children – in a strike on an elementary school. The official number of dead and wounded U.S. personnel stands at 426, an almost 11 percent increase since the first ceasefire between the U.S. and Iran was struck on April 8. This tally, however, is missing hundreds of casualties, including two soldiers wounded in action earlier this month.

For months, The Intercept has reported that the Pentagon’s official tally of dead and wounded military personnel from the Iran War is a gross undercount, stemming from what another U.S. government official called a “casualty cover-up.” The Defense Casualty Analysis System, or DCAS, which tracks “deceased, wounded, ill or injured” service members for Congress and the president, is missing hundreds of known casualties. The true number exceeds 625.
