Ecuador has granted citizenship to WikiLeaks founder Julian Assange, Ecuador's Foreign Minister Maria Fernanda Espinosa announced Thursday. She called the measure one more ring of protection" for Assange, who has been holed up at the Ecuadorian Embassy in London since 2012 in an effort to avoid a Swedish arrest warrant. Sweden dropped the charges in May 2017, but Assange remains the subject of a UK arrest warrant. Assange ... has previously expressed concern that if he leaves the Ecuadorian embassy in London he could end up being extradited to the US, where he fears facing the death penalty over allegations of revealing government secrets through WikiLeaks. In December, the Ecuadorian government requested diplomatic status for Assange. But the UK rebuffed the request. Espinosa said Ecuador will continue to pursue a dialogue with the UK to eventually remove Assange from the embassy. "We will continue to protect Julian Assange while his physical and psychological integrity are at risk," Espinosa said. "We are a country that defends human rights and ... respects international law." A 2016 United Nations report concluded that the WikiLeaks founder had been arbitrarily detained by Sweden and the United Kingdom.
