WikiLeaks founder Julian Assange said he will "absolutely" publish private information about the UK's drone attacks in Syria if he is offered it.

The Australian insisted that WikiLeaks has not published anything that would assist Islamic State (IS) and partly blamed poor press coverage for the rise of the terror organisation.

Assange, who has spent three years at the Ecuadorian embassy since being granted political asylum, made the comment while being interviewed about his latest book, The WikiLeaks Files.

Asked by Channel 4 News whether he would publish details about the UK's controversial drone strike if given the opportunity, Assange said: "Absolutely. We would have to see the actual material. We get together a bunch of experts and publishers and publish it.

"We will occasionally redact parts on human rights grounds but only for a limited period of time."

He added: "There's no allegation anything we have published has benefited the Islamic State, but let's go back. It's the failure of the press here to properly cover what has been happening in Syria (that) has led to the rise of the IS. That's a very, very serious phenomenon.

"The intelligence agencies have run amok, military supplies have run amok, Saudi Arabia and Qatar and Turkey have run amok and as a result we now have the Islamic State, where we have incredible refugee flows, a human rights catastrophe.

"I'm someone who believes that education about how the world actually works, how human institutions actually behave, is really the only thing that we have.

"Otherwise it's just a chaos because our decisions are not based on understanding."

He also blamed the US and UK for giving the IS a stronghold in the Middle East by destabilising the area.

Assange believes he risks extradition to the US from the UK and Sweden, where he is under investigation for his involvement with WikiLeaks. He also faces extradition to Sweden for an investigation into an alleged rape.
