Julian Assange

WikiLeaks founder Julian Assange lost an attempt Tuesday to have his U.K. arrest warrant dropped. He could still be arrested for leaving Ecuador's embassy in London, where he has lived for years.

British Judge Emma Arbuthnot said she was "not persuaded" the warrant should be withdrawn, according to The Associated Press.

Ecuador says it has granted citizenship to Wikileaks founder Julian Assange, as officials try to find a way for him to leave the Ecuadorean embassy in London without risking legal action.

Assange, who is Australian, first sought refuge at the embassy more than five years ago to avoid extradition to Sweden, where he faced an investigation over rape allegations. He was granted asylum, and has been holed up in the embassy ever since.

Swedish prosecutors have announced they are dropping the country's rape investigation of Julian Assange. The WikiLeaks founder, who has long denied the allegation, has been holed up at the Ecuadorean Embassy in London since 2012 to avoid Sweden's extradition request.
