A US warplane killed multiple Iranian-backed militiamen in Iraq after they fired a short-range ballistic missile at American and allied personnel in the country, the Pentagon said on Tuesday. “We can confirm an attack last night by Iran-backed militias using a close-range ballistic missile against US and coalition forces at Al-Asad Airbase, which resulted in eight injuries and some minor damage to infrastructure,” Pentagon spokesman Brigadier General Pat Ryder said in a statement. “Immediately following the attack, a US military AC-130 aircraft in the area conducted a self-defense strike against an Iranian-backed militia vehicle and a number of Iranian-backed militia personnel involved in this attack. This self-defense strike resulted in several enemy KIA (killed in action),” Ryder said.
