WASHINGTON (AP) — A U.S. airstrike in Syria in May 2023 that was targeting an al-Qaida leader killed an innocent civilian instead, U.S. Central Command said Thursday, confirming early reports from residents and family members shortly after the attack.

U.S. Central Command said an investigation into the May 3 strike concluded that U.S. forces misidentified the intended al-Qaida target “and that a civilian, Mr. Lufti Hasan Masto, was struck and killed.”

Shortly after the drone strike, the Syrian Observatory for Human Rights, an opposition war monitor, said it had hit a chicken farm near the town of Harem, killing one person. And just days later, relatives and neighbors told The Associated Press that the person killed was a farmer who raised sheep, chickens and cattle and had no involvement with armed groups.

Masto’s brother, Mohamed Masto, said reports that his brother, 60, was involved with al-Qaida were “absolute lies” and his killing was “an injustice and an aggression.” Instead, Masto was simply tending his sheep when the strike hit.
