LONDON (AP) — After fighting for more than a decade to avoid being sent to the U.S., WikiLeaks founder Julian Assange is facing further delays in learning whether he can make a new legal challenge against his extradition.

Assange, 52, faces charges related to his organization’s publication of a huge trove of classified documents. He has been in custody in a high-security London prison since 2019, and previously spent seven years in self-exile in the Ecuadorian Embassy in London.

As judges at London’s High Court adjourned his case Tuesday to give U.S. authorities more time to submit assurances about what would happen to him if he is extradited, here is a look at key events in the long-running legal saga:

— 2006: Assange founds WikiLeaks in Australia. The group begins publishing sensitive or classified documents.

— 2010: In a series of posts, WikiLeaks released almost half a million documents relating to the U.S. wars in Iraq and Afghanistan.

— August 2010: Swedish prosecutors issue an arrest warrant for Assange based on one woman’s allegation of rape and another’s allegation of molestation. The warrant is withdrawn shortly afterward, with prosecutors citing insufficient evidence for the rape allegation. Assange denies the allegations.
