Iran has insisted that it did not send any ballistic missiles to Russia.

Abbas Araqchi, the Iranian foreign minister, also criticised the sanctions that have been imposed by the UK and the US in the wake of the weapons being send for Moscow’s use.

Antony Blinken, who is in Kyiv today, said the US had confirmation that Fath 360 missiles were sent to Russia and would be used in Ukraine “within weeks”.
