The US has said it is deeply concerned by reports that Iran is planning to deliver hundreds of ballistic missiles to Russia.
State department deputy spokesperson Vedant Patel told reporters this afternoon that such a move would represent a dramatic escalation.
For context: On Friday, reports emerged that dozens of men in the Russian military were being trained in Iran to use the Fath 360 close-range ballistic missile system.
Two intelligence sources also told Reuters that they expected the imminent delivery of hundreds of the satellite-guided weapons to Russia.
Russian officials are believed to have signed a contract with Iranian officials last December in Tehran for the missiles.
