The airstrikes conducted by the US military targeted Iranian-backed groups in Deir ez-Zor Syria, US Central Command said in a statement. The strikes targeted “infrastructure facilities used by groups affiliated with Iran’s Islamic Revolutionary Guard Corps,” Col. Joe Buccino, a spokesman for CENTCOM, said in the statement.

“At President Biden’s direction, US military forces conducted precision airstrikes in Deir ez-Zor Syria today. These precision strikes are intended to defend and protect US forces from attacks like the ones on August 15 against US personnel by Iran-backed groups,” he said, referring to last week’s attacks on the Green Village base near the Iraqi border. The incident did not result in damage or injuries.

Biden, according to the statement, “gave the direction for these strikes pursuant to his Article II authority to protect and defend US personnel by disrupting or deterring attacks by Iran-backed groups.”
