"The suggestion that as long as the death penalty is off the table, Mr Assange need not fear persecution is obviously wrong ..."
Ecuadorean President Lenin Moreno said there was a "path" for WikiLeaks founder Julian Assange to leave the South American country's London embassy, where he has lived for six years under asylum, if he so chooses.
Moreno, however, said Britain had guaranteed that the 47-year-old Australian would not be extradited to any country where his life would be in danger.
In a media interview, Moreno said he had received written assurances from Britain that Assange could leave the building safely.
Assange's statement doesn't preclude extradition on non-capital charges, however, and on November 15, US federal prosecutors accidentally revealed that Assange had been fingered under seal in the ongoing investigation into Russian meddling in the 2016 USA presidential election.
Federal criminal charges against Assange have been filed secretly in the United States and were accidentally leaked in a court filing for an unrelated case several weeks ago.
WikiLeaks has been a focus of special counsel Robert Mueller's investigation of any links between associates of President Donald Trump and Russian efforts to interfere in the 2016 presidential election. The investigation in Sweden was later dropped, and Ecuador said there were no pending extradition requests against Assange.
"We will protect Mr. Assange's rights - this is why we are looking for a solution, but this needs to be an agreed solution", he said.
In November, WikiLeaks suggested that the U.S. authorities might have brought sealed charges against Assange, citing a filing in an unrelated case that used Assange's name in an "apparent cut-and-paste error".
Assange took refuge in the Ecuadoran embassy in London in 2012 to avoid extradition to Sweden to face questioning in two alleged cases of sexual assault.
He also commented on the extraordinary length of time Mr Assange has been living in the embassy. The Justice Department prepared an indictment against the WikiLeaks founder in which prosecutors inadvertently mentioned charges against him.
