The United States has expressed deep concern over reports that Iran plans to deliver hundreds of ballistic missiles to Russia. This potential transfer, involving the Fath-360 short-range ballistic missile system, is seen as a significant escalation in Iran's support for Russia's military efforts in Ukraine. According to two European intelligence sources, Russian military personnel are currently being trained in Iran to operate these missile systems. In response, the U.S. State Department, along with its European partners, is considering measures to counter this move and has warned of a 'swift and severe response' should Iran proceed with the missile transfer.
