US retaliates against Iran-backed militants after ballistic missile strike (msn.com)
"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 damage to infrastructure. Immediately following the attack, a U.S. 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," said Pentagon Press Secretary Brig. Gen. Pat Ryder.
"This self-defense strike resulted in some hostile fatalities."
