The U.S. military fighter dropped two bombs on a crowd of people, mostly women and children who were trying to escape the fighting on the banks of the Euphrates, just near the Syria-Iraq border. The crowd had been identified as civilians by a U.S. drone operated from Al-Udeid airbase in Qatar. According to the report by The New York Times, the drone operators were stunned seeing the first 500lb bomb dropped by a US F-15E plane followed by a second 2,000lb bomb targeting the survivors.
