Assange supporters 'not optimistic' ahead of final appeal against US extradition

Supporters of Julian Assange, including his wife Stella and the editor in chief of Wikileaks, Kristinn Hrafnsson, hold a press conference ahead of his final appeal against extradition from the UK to the United States.

The US wants to put the Australian publisher on trial for divulging American military secrets about the wars in Iraq and Afghanistan.

A two day hearing is set to begin at the High Court in London on February 20.
