Pentagon: US Killed ‘Iranian-Affiliated Militants’ in Retaliatory Strikes in Syria 
According to Pentagon, US troops used attack helicopters, gunships, M777 artillery during strikes 
pentagon — At least three “Iranian-affiliated militants” were killed in multiple U.S. strikes in northeast Syria over the past 24 hours, the Pentagon said Thursday. Pentagon press secretary Air Force General Pat Ryder told reporters the first U.S. strike was in response to Wednesday’s rocket attacks against two U.S. mission support sites, in which three U.S. service members suffered minor injuries. The U.S. strike killed two to three militants, according to an initial assessment. Hours later, a “follow-on self-defense” strike targeted Iranian-backed militants who were attempting to launch rockets at American forces, killing one militant, according to Ryder. “The U.S. military will respond appropriately and proportionately to any attacks on our service members and will continue to take all necessary measures to defend our people,” Ryder said. According to the Pentagon, U.S. troops used attack helicopters and gunships along with M777 artillery during the strikes, which destroyed 10 rocket launchers. On Tuesday, the U.S. carried out airstrikes in eastern Syria that it said targeted an ammunition depot and other facilities used by groups linked to Iran’s Revolutionary Guard Corps. Iran denied Wednesday any link to the sites. Iranian forces have been in Syria supporting President Bashar al-Assad’s forces during Syria’s civil war. The United States has about 900 troops in Syria working with the Kurdish-led Syrian Democratic Forces to combat the Islamic State group.
