Supporters hail Assange as a free-speech icon who has invited the wrath of a vengeful US for exposing misdeeds that have embarrassed the superpower. They fear he will be sent to that country to face trial and will probably be punished for his heroism.
The language, in a letter to him in his native German, suggested that prosecutors had not, at least at that point, abandoned the possibility of charges based on WikiLeaks’ publication of U.S. government secrets.
Ecuadorian Foreign Minister José Valencia said Assange's behaviour was "undeserving, disrespectful" and he pointed to a video which appears to show Assange arguing with an official inside the Ecuadorian embassy in London.
WikiLeaks incensed Washington by publishing hundreds of thousands of secret US diplomatic cables and in 2010 a classified US military video showing a helicopter attack in Baghdad in 2007 that killed a dozen people, including two Reuters news staff.
Foreign Minister José Valencia said in an interview with Reuters that Ecuador's only responsibility was looking after Assange's wellbeing after the Australian national sued the country over new conditions placed on his asylum in the London embassy.
