U.S. Defense Secretary Lloyd Austin III on Monday ordered a new high-level investigation into a U.S. airstrike in Syria in 2019 that killed dozens of women and children, the Pentagon said.

The investigation by Gen. Michael Garrett, the four-star head of the Army’s Forces Command, will examine the strike, which was carried out by a shadowy Special Operations unit called Task Force 9. It will also look into the military’s initial inquiries into the strike, Pentagon officials said.

Garrett will have 90 days to review the inquiries and further investigate record-keeping errors, reports of civilian casualties, whether any violations of laws of war occurred, whether any recommendations from previous reviews were carried out, and whether anyone should be held accountable, the officials said. .

Austin’s decision comes after a New York Times investigation this month that described allegations that top officers and civilian officials had sought to conceal the casualties from the airstrike. The attack, which took place near the Syrian town of Baghuz on March 18, 2019, was part of the final battle against Islamic State group fighters in a shard of a once-sprawling religious state across Iraq and Syria. It was among the largest episodes of civilian casualties in the yearslong war against the Islamic State group, but the U.S. military had never publicly acknowledged it.

The Times investigation showed that the death toll — 80 people — was almost immediately apparent to military officials. A legal officer flagged the bombing as a possible war crime that required an investigation. The Defense Department’s independent inspector general began an inquiry, but the report containing its findings was stalled and stripped of any mention of the strike.

John Kirby, the Pentagon’s chief spokesperson, said Austin had decided to ask for the inquiry after speaking with Gen. Kenneth McKenzie Jr., commander of Central Command.


Kirby called Austin’s appointment of Garrett, a senior four-star general, “a reflection of how seriously he is taking the issue.”

He announced the inquiry after the Defense Department notified Congress. The House and Senate Armed Services Committees have both said that they are investigating the strike.

In a news conference two weeks ago, Austin vowed to overhaul military procedures and hold top officers responsible for civilian harm, but he did not outline any systemic problems that had allowed civilian casualties to persist on battlefields in Syria and Afghanistan.

The classified task force that investigated the Syria strike acknowledged that four civilians were killed, but it also concluded that there had been no wrongdoing by the Special Operations unit. In October 2019, the task force sent its findings to the Central Command headquarters in Tampa, Florida.

But officials at Central Command did not follow up and failed to remind a subordinate military headquarters in Baghdad to do so, in what Capt. Bill Urban, a Central Command spokesperson, described as “an administrative oversight.” As a result, senior military officials in Iraq and Florida never reviewed the strike, and the investigation technically remained open until the Times investigation.

Austin, who became defense secretary this year, received a classified briefing this month about the strike and the military’s handling of it from McKenzie, who oversaw the air war in Syria.


In an email to the Senate Armed Services Committee last spring, the legal officer who witnessed the strike warned that “senior ranking U.S. military officials intentionally and systematically circumvented the deliberate strike process,” and that there was a good chance that “the highest levels of government remained unaware of what was happening on the ground.”

A spokesperson for the Armed Services Committee, Chip Unruh, said the panel “remains actively engaged and continues to look at the matter.” Rep. Adam Smith, D-Wash, chair of the House Armed Services Committee, announced this month that his panel would also investigate the strike and the military’s handling of it.

The Times investigation found that the bombing by Air Force F-15E attack jets had been called in by Task Force 9, a unit largely made up of the U.S. Army’s elite Delta Force. The task force was in charge of ground operations in Syria, working closely with Syrian Kurdish and Arab militia. Military personnel who spoke to the Times said the secretive task force circumvented oversight by claiming that a vast majority of its strikes required immediate action to protect allied troops from imminent threat. Often, military officers said, no such threat was present.

After the Times sent its findings to Central Command, the command acknowledged the attack for the first time. It said in a statement that the 80 deaths were justified because the task force had launched a self-defense strike against a group of fighters who were an imminent threat to allied forces on the ground.

Central Command told the Times that the strike had included three guided bombs: a 500-pound bomb that hit the initial group and two 2,000-pound bombs that targeted people fleeing the initial blast. The command later corrected itself, saying all three bombs were 500-pound munitions.

The command said the three strikes killed 16 fighters and four civilians. As for the other 60 people killed, the statement said it was not clear that they were civilians, in part because women and children in the Islamic State group sometimes took up arms.


A report by the Defense Department’s inspector general released this month found there was a credible allegation of a law of war violation, but it was not correctly reported or investigated. It recommended that Central Command strengthen processes to ensure that episodes are promptly reported. In its response, Central Command pushed back, saying it was the commander who decided what counted as credible allegation of a violation, not the service members reporting it.

Some military experts criticized the Pentagon for not ordering an independent review of the strike.

“Once again, we’ll be asked to trust that the U.S. military can grade its own homework,” said Sarah Holewinski, Washington director of Human Rights Watch and a former senior adviser on human rights to the military’s Joint Staff. “I’ve seen these investigations into civilian deaths in Afghanistan, Iraq and Syria. In none of them was anyone held accountable.”

In addition to the new investigation into the Syria strike, Austin is still weighing newly submitted plans from top commanders on how to mitigate civilian casualties in military operations worldwide. Those steps were recommended in a separate investigation into a drone strike in Kabul, Afghanistan, on Aug. 29 that killed 10 civilians, including seven children.

Those recommendations are expected to be included in a larger Pentagon policy overhaul intended to mitigate civilians casualties that is now underway, Defense Department officials said Monday.
