The US military never conducted an independent investigation into a 2019 bombing on the last Daesh holdout in Syria ordered by a classified special operations unit.
A scathing report published by the New York Times has revealed that the US military covered up 2019 airstrikes in Syria that killed up to 64 women and children during the battle against Daesh.
The two back-to-back airstrikes saw two US fighter jets drop a 227 kg bomb on a crowd, followed by another 907 kg bomb on the same target near the town of Baghuz.
The strikes were ordered by a classified American special operations unit tasked with ground operations in Syria, the New York Times reported on Saturday.
US Central Command, which oversaw US air operations in Syria, acknowledged the strikes for the first time this week and said they were justified, according to the Times investigation.
Central Command also reiterated the account that 80 people were killed in the strikes including 16 Daesh terrorists and four civilians.
The military said it was unclear if the other 60 people were civilians, partly because women and children could have been combatants. In Saturday's statement, the military said the strikes were "legitimate self-defense," proportional and that "appropriate steps were taken to rule out the presence of civilians."
Possible war crimes
An Air Force lawyer present in the US operations centre at the time believed the strikes were possible war crimes and later alerted the Defense Department's inspector general and Senate Armed Services Committee when no action was taken, the Times said.
"We abhor the loss of innocent life and take all possible measures to prevent them. In this case, we self-reported and investigated the strike according to our own evidence and take full responsibility for the unintended loss of life," Central Command said.
The number of civilians among the 60 fatalities could not be determined because "multiple armed women and at least one armed child were observed" in a video of the events, it said, before adding that the majority of the 60 were likely combatants.
Central Command said the strikes took place while Syrian Democratic Forces (SDF) were under heavy fire and in danger of being overrun, and the SDF had reported the area clear of civilians.
The Defense Department's inspector general launched an inquiry into the March 18, 2019, incident, but its report was ultimately "stripped" of any mention of the bombing and a thorough, independent probe never took place, according to the Times.
The newspaper said its report was based on confidential documents and descriptions of classified reports, as well as interviews with directly-involved personnel.
