Wikileaks man says Pentagon may be behind rape claims

The country's prosecution service meanwhile justified the chaotic situation when authorities first issued an arrest warrant for the Australian whistleblower late on Friday night but then withdrew it the following day.

The Aftonbladet newspaper quoted Assange, 39, as saying he did not know who was "hiding behind" the claims, which came amid a stand-off with Washington over the website's publication of secret Afghan war documents.

Assange said he was shocked by the allegations against him and that he had never had sexual relations with anybody in a way that was not consensual, the tabloid said.

But he said that he had been warned previously that groups such as the Pentagon "could use dirty tricks" to destroy Wikileaks -- adding that he had been particularly warned against being entrapped by sexual scandals.

Assange told Aftonbladet that despite the lifting of the warrant, his enemies would still use the claims to damage Wikileaks, which is set to publish thousands more secret papers about the war in Afghanistan in coming weeks.

He refused to give more details about the two women whose claims sparked the furore, saying that it would impinge on their privacy.
