The United States has expressed deep concern over reports that Iran is planning to send hundreds of ballistic missiles to Russia.
Deputy State Department Spokesperson Vedant Patel told reporters this afternoon that such an action would represent a dramatic escalation, according to Sky News.
On Friday, reports emerged that dozens of Russian military personnel were being trained in Iran to use the Fath 360 short-range ballistic missile system.
Two intelligence sources also told Reuters they expected the imminent delivery of hundreds of satellite-guided weapons to Russia.
Russian officials are said to have signed a contract with Iranian officials in Tehran last December for the missiles.
