A Swedish appeals court has decided to uphold an arrest warrant for Julian Assange on Friday, continuing a six-year legal standoff between prosecutors and the WikiLeaks founder.Assange, 45, is wanted by Swedish authorities for questioning over allegations, which he denies, that he committed rape in 2010.‘The court of appeal shares the assessment of the district court that Julian Assange is still suspected on probable cause of rape,’ the court said.Assange sought refuge in the Ecuadorian embassy in London in June 2012 after exhausting all his legal options in Britain against extradition to Sweden. He says he fears further extradition to the US, where a criminal investigation into WikiLeaks’ release of 500,000 secret military files on the wars in Afghanistan and Iraq is ongoing.Friday’s hearing was the eighth time the European arrest warrant has been tested in a Swedish court, with all seven previous rulings having gone against him.On Thursday WikiLeaks released medical records claiming Assange’s mental health was at risk if he remained confined in the embassy.‘Mr Assange’s mental health is highly likely to deteriorate over time if he remains in his current situation … It is urgent that his current circumstances are resolved as quickly as possible,’ said a report published by the organisation on Twitter.The 27-page medical report accompanied by supporting documents is attributed to an unnamed ‘trauma and psychosocial expert’ in London and dated 11 December 2015.
