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.
A Justice Department investigation of Assange and WikiLeaks dates to at least 2010, when the site posted thousands of files stolen by the former US Army intelligence analyst now known as Chelsea Manning.
In a radio interview on Thursday, Moreno said Britain has provided sufficient guarantees that they would not extradite the Australian activist to any country where he would face the death penalty.
Julian Assange speaks to the media from the balcony of the Embassy Of Ecuador on May 19, 2017 in London, England. The indictment suggested that the USA will seek Assange's extradition if he leaves the embassy, though the charges he faces were not known.
Sweden has since dropped that case, and Ecuador says there are no pending extradition requests against the WikiLeaks founder. He has been staying in the embassy amid the fear of being extradited to the United States if he attempted to leave.More news: US resolution condemning Hamas over Israel fails at United Nations

There is speculation that the U.S. interest in Assange is connected to the investigation by Special Counsel Robert Mueller into Russian interference in the 2016 election that brought President Donald Trump to office. He faces charges of espionage, conspiracy, theft of government property, and computer fraud in the United States, and Donald Trump's administration has stated that the Wikileaks founder's arrest is a top priority.
Mueller charged 12 Russian spies in July with conspiring to hack the Democratic National Committee in an effort to sway the election.
Assange has remained in Ecuador's embassy in London for fear that he will be extradited to countries where he is wanted or that he will be arrested in the United Kingdom for the criminal offence of breaching his bail conditions.
His lawyer, Carlos Poveda, said last month that Assange was prepared to give himself up to British police provided he receives assurances he would not be extradited.
Moreno said the sentence for skipping bail would be "not long".
