The British Supreme Court dismissed WikiLeaks founder Julian Assange's appeal Thursday against its ruling in favor of extraditing the former computer hacker to Sweden to face sex crime allegations.

The court's seven judges unanimously agreed to toss out Assange's second appeal and stand by their May 30 decision to support sending him to Sweden to face the accusations of sexual coercion and rape lodged by two women he had sex with on a trip to Stockholm.

Assange's lawyers filed the appeal Tuesday.

Assange, who has been under house arrest in rural England for 555 days, may now appeal to a transnational European court in Strasbourg, a supreme court spokesman told TheWrap.

High-profile human rights attorney Gareth Peirce, the spokeswoman for Assange's legal team, did not respond to requests from TheWrap to comment.

The Swedish prosecutors who issued the warrant seek to question the WikiLeaks editor over allegations that he sexually forced two women to have unprotected sex.

Assange rose to international prominence in 2010 after WikiLeaks, a whistle-blowing website he designed and edited, published the largest leak of classified U.S. documents in history, including combat videos and a massive trove of diplomatic cables that candidly detailed the wars in Iraq and Afghanistan.
