Australian WikiLeaks founder Julian Assange was beamed live by satellite from within the Ecuadorean embassy in London to Wednesday's United Nations forum, when he called on the United States government to end its pursuit of his whistleblower website.

"It is time for the US to cease its persecution of WikiLeaks, to cease its persecution of our people, and to cease its persecution of our alleged sources," Mr Assange told the Strengthening Human Rights meeting.

"It is time for President [Barack] Obama to do the right thing ... not in fine words, but in fine deeds."
