US Army sergeant from Queens killed in Iranian attack on Jordan baseWhy did Pentagon change casualty count?According to The New York Times, three US military officials said the casualty total was reduced after the Trump administration decided to remove four service members killed over the weekend from the official Iran war tally.The officials, who spoke on condition of anonymity, said the four deaths included three soldiers killed at Muwaffaq Salti Air Base in Jordan and one service member killed in northern Iraq. They said the administration concluded those deaths occurred after President Donald Trump declared a ceasefire in the conflict and therefore should not be counted as wartime fatalities.The Pentagon, however, publicly offered a different explanation.Acting Pentagon press secretary Joel Valdez attributed the discrepancy to “temporary data disruptions” and described the revised figures as the result of “site anomalies” that were being corrected."We remain committed to ensuring the utmost accuracy of all casualty reporting," Valdez said. He also criticised The New York Times report, calling it "a non-story."Trump says otherwise, gives higher death countDespite the explanation, President Trump continued referring to the higher figure during remarks on Thursday. Speaking about the conflict, Trump said, "Even one death is too many, but it's 18," despite the Pentagon website showing 14 fatalities by that time.He said, “We’re going to Dover to honor our heroes, and they’re indeed great heroes. All of them said, very strongly, that we can’t let Iran have a nuclear weapon.”Also read: Trump pays respects to 4 US service members killed in the Middle EastLimited information from the PentagonThe updated numbers coincide with more widespread criticism of the Pentagon's handling of Iran-related material.According to The New York Times, the Defense Department has released limited information about US military operations since the ceasefire collapsed.
