Wikileaks founder Julian Assange is trying from Tuesday to obtain from British justice a last resort against his extradition to the United States. As the hearing approaches, his supporters warned of the risks weighing on the life of the 52-year-old Australian.

Julian Assange faces up to 175 years in prison for having published since 2010 more than 700,000 confidential documents on American military and diplomatic activities. Among them was a video showing civilians, including two Reuters journalists, killed by fire from a US helicopter gunship in Iraq in July 2007.
