The internet is one of the few, if not only, available ways for Julian Assange, who has been locked up in the Ecuadorian Embassy in London for more than four years, to maintain contact with the outside world.

Facing extradition to Sweden over allegations of rape, which he denies, the Australian computer programmer has been holed up in the embassy in West London since 2012.

He claims the extradition is actually a bid to move him to a jurisdiction from which he can then be sent to the US, which is known to be actively investigating WikiLeaks. 

The unverified claims of state sabotage come as WikiLeaks continues to release damaging documents, most recently thousands of hacked emails from Hillary Clinton's campaign manager John Podesta.

Earlier this month, Assange claimed his organization would aim to publish documents "every week" in the run up to US Election Day on November 8. 

Clinton's campaign has made unsubstantiated claims that WikiLeaks is working with the Russian government to help defeat the Democrat in favor of Trump.

Last week the FBI reissued a statement saying it was working to "determine the accuracy, nature and scope" of cyber intrusions, but did not name any suspected perpetrators.
