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 (1,242 miles), was shown on state TV. It is unclear when the test took place, reports the BBC.

At the UN on Tuesday, Mr Trump 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 Khoramshahr missile was first displayed at a military parade on Friday in Tehran. It is capable of carrying multiple warheads, Iranian media report.

Iran's Defence Minister, Gen Amir Hatami, outlined the missile's "unique specifications".

"The ability to evade the enemy's air defence line and to be guided from the moment of launch until the target is hit turns Khoramshahr into a tactical missile," he said.

Iran would "not seek permission from any country for producing various kinds of missile", he added.

By test-firing a new missile, Iran is sending another signal of defiance taken straight from the North Korean textbook.

The missile test is arguably a borderline case as far as the UN Security Council is concerned. A resolution calls on Iran not to undertake any activity related to ballistic missiles designed to be capable of delivering nuclear weapons.

Iran's test is a message to the US that it is determined to defend itself in any way it sees fit but it could also ultimately work against Iran as world public opinion will compare it to North Korea.

Missile tests in Iran are said to require the approval of Mr Rouhani, and now it seems he has been pushed into a corner with the hardliners in Iran who see the North Korean path as the best response to Mr Trump's rhetoric and his disdain for the nuclear deal.
