London (CNN) WikiLeaks' Editor-in-Chief said Wednesday the group has "uncovered an extensive spying operation against Julian Assange" in the Ecuadorian embassy in London where he has lived under asylum since 2012, likening it to the movie "The Truman Show."

Speaking at a press conference in the British capital, Kristinn Hrafnsson said surveillance of WikiLeaks' founder Assange included video and audio recordings from various recorders inside the embassy, including footage of a medical examination of Assange as well as legal meetings and legal documents.

Wednesday's allegations ramped up the war of words between Ecuadorian authorities and WikiLeaks, which claims there has been an escalating effort to push Assange out of the embassy, with the aim of getting him extradited to the United States.

Fidel Narvaez, Ecuador's former consul to London, said he did not believe that Ecuador was protecting Assange any longer, describing him as a political refugee.
