The group’s editor-in-chief, Kristinn Hrafnsson, told a news conference that Assange’s meetings with lawyers and a doctor had been secretly filmed by Ecuadorian authorities.
Assange sought refuge in the Ecuadorian Embassy in London in 2012 and has been living there ever since.
Sweden has dropped an investigation into rape allegations against Assange, but he refuses to come out for fear of facing U.S. charges related to WikiLeaks’ publication of classified documents. He also faces arrest in Britain for jumping bail.
Relations between Assange and his Ecuadorian hosts have turned sour in recent weeks with a series of accusations from both sides. Assange’s team fears he may be expelled from his refuge.
Ecuador’s vice president, Otto Sonnenholzner, says Assange will have to “abide by the consequences” if he is found to have violated an embassy protocol put in place in October.

Speaking to the Sonorama radio station, he said, “The only thing Ecuador demands is fulfillment of the protocol, a protocol that limits certain privileges.”
He said the protocol imposed in October has allowed the country to cut its budget for maintaining Assange, which officials had estimated at $1 million a year. It sets rules on visits, medical spending, food, internet use and other issues.
Sonnenholzner said Foreign Minister José Valencia will present a report about compliance with the protocol to President Lenín Moreno on Wednesday, and will do the same on Thursday to congressional leaders.
Following the report, he said, “we will see … what happens in that situation.”
