Iran says it has successfully tested a new-medium range missile, in defiance of US President Donald Trump.

The launch of the Khoramshahr missile, which has a range of 2,000 km (1242 miles), was shown on state TV. It is unclear when the test took place.

At the UN on Tuesday, Mr Trump had criticised Iran’s missile programme and the 2015 nuclear deal with the country.

On Friday Iranian President Hassan Rouhani said Iran would increase its military power “as a deterrent”.

The US imposed sanctions on Iran after a ballistic missile test in January.

The Khoramshahr missile was first displayed at a military parade on Friday in Tehran.
