LONDON — WikiLeaks will step up its publication schedule of secret documents, founder Julian Assange announced Tuesday, promising more revelations based on the group's stash of confidential US embassy cables and other leaks.Assange, 39, spoke to reporters outside London's high-security Belmarsh Magistrates' Court, where he and his lawyers appeared for a hearing in his fight against extradition to Sweden, where he is wanted in a sex-crimes inquiry.RELATED:WikiLeaks sparked an international uproar with the publication of hundreds of classified US diplomatic cables late last year, revelations that caused weeks worth of embarrassing news stories for the US and its allies. But the flow of leaks, published in The New York Times, The Guardian, Der Spiegel, Le Monde and El Pais, has slowed recently amid a barrage of online attacks, financial difficulties and the Swedish prosecution of Assange.The Australian computer expert said that would soon change, hinting that new media outlets were being made party to the leaks."We are stepping up our publishing for matters related to Cablegate and other materials," Assange said. "Those will shortly be occurring through our newspaper partners around the world — big and small newspapers and some human rights organizations."He did not elaborate, returning to court with his lawyers without taking questions.The WikiLeaks frontman has been under strict curfew at a manor in eastern England since his arrest last month on rape and molestation accusations stemming from encounters with two women during a trip to Sweden last summer.The Swedish case has divided world opinion. Assange and his supporters say he is being prosecuted for political reasons, something denied by Swedish authorities and Assange's alleged victims, who insist it has nothing to do with WikiLeaks' activities.Assange, wearing a dark suit, was in court for just 10 minutes for a discussion of his next appearance, scheduled for February 7.A few people protested outside the court, with one standing behind a banner proclaiming: "Welcome to the show trial."
