The ruling in Stockholm came a day after Interpol, the global police body, said it had been circulating a red notice seeking Assange’s arrest for almost two weeks.
Kerstin Norman, a Swedish High Court official, said the court’s ruling on Thursday meant that earlier calls for Assange’s arrest were still in force, Reuters reported.
Also on Wednesday, WikiLeaks accused Amazon.com of ending an agreement to host its website.
Amazon hosts the sites of many companies and organizations as part of its Amazon Web Services program.
WikiLeaks on Sunday released 250,000 classified US documents, some of which touch on issues ranging from US involvement in spying against the UN to the involvement of US embassies across the world in espionage activities.
In a message posted on Twitter, WikiLeaks said its servers at Amazon had been “ousted,” adding that its money would now be spent “to employ people in Europe.”
“If Amazon is so uncomfortable with the first amendment, they should get out of the business of selling books.”
Senator Joseph I. Lieberman, an independent of Connecticut, said Amazon stopped hosting the WikiLeaks site on Wednesday after being contacted by the staff of the Homeland Security and Governmental Affairs Committee.
The Swedish prosecutor’s office said almost two weeks ago that a court in Stockholm had approved a request for the arrest of Assange to face questioning on suspicion of “rape, sexual molestation and unlawful coercion.”
He has strongly denied the charges. Appeals by Assange to suspend the warrant have been unsuccessful.
