The United States said Friday that its strikes in eastern Syria hit ammunition linked to Iran’s elite Islamic Revolutionary Guard Corps (IRGC) and expected a “significant” impact on Tehran-backed militias. “The purpose for those two sites that we targeted was to have a significant impact on future IRGC and Iran-backed militia group operations,” National Security Council spokesman John Kirby told reporters. “It went right at storage facilities and ammo depots that we know will be used to support the work of these militia groups, particularly in Syria.”
