Iran tests new ballistic missile: state media

Iran has "successfully" tested a new ballistic missile that can carry multiple warheads and can travel up to 2,000km, according to state media.

The news of the test comes just hours after Iran's Revolutionary Guard unveiled the missile during a military parade in Tehran.

The move was a direct challenge to US President Donald Trump, who in August signed a bill imposing mandatory penalties on those involved in Iran's ballistic missile programme and anyone who does business with those involved in the programme.

Though Iran has long boasted of having missiles in the same range in its arsenal, it was the first time that the Khorramshahr missile was displayed in public.

Trump has vowed repeatedly to take a tougher line towards Iran, threatening at various time to renegotiate or dismantle the 2015 nuclear deal, and shoot Iranian boats out of the water if they provoke US naval vessels.
