The editor in chief of a leading US news website has demanded that Iran be annihilated because it is inherently "evil".

The Daily Caller's Tucker Carlson told Fox News that the US should wipe out the country as tensions mount over the Islamic republic's nuclear ambitions.

In the interview, Carlson, who is also a commentator for the channel, said the world was divided between good (the US and its allies) and evil (Iran).

He called for Iran to be wiped off the face of the Earth.

"We are the only country with the moral authority sufficient to do that," he said.

"[The US is] the only country that doesn't seek hegemony in the world. I'm sure I'm the lone voice in saying this that Iran deserves to be annihilated. I think they're lunatics. I think they're evil."
