Mr. Assange ran Wikileaks, a website that published numerous confidential or restricted official reports related to war, espionage and corruption.
In 2010, he released video from a US military helicopter showing civilians killed in Baghdad, the Iraqi capital.
He also published thousands of confidential documents provided by Chelsea Manning, former US Army intelligence analyst. This evidence suggests that the US military killed hundreds of civilians in unreported incidents during the war in Afghanistan.
These revelations have become a hot topic, sparking reactions from all corners of the globe and leading to increased scrutiny of American involvement in foreign conflicts.
The United States said the leaks endangered the lives of American personnel.
Mr. Assange has been accused of conspire to break into its military databases, external to acquire sensitive information and was charged with 18 offenses.
Efforts were made to bring him to the United States to stand trial – something he fought for 14 years in some of the world’s highest courts.
Mr. Assange has always maintained that he exposed serious abuses committed by the US armed forces and that the accusations against him were politically motivated.
