Swedish authorities issued an arrest warrant for Assange on rape suspicions this weekend but quickly withdrew it. The Australian remains under suspicion of a lesser crime of molestation.
Aftonbladet quoted Assange as saying he hasn't had sex with anyone in a way that wasn't consensual.
He said the allegations had damaged the whistleblower site because WikiLeaks' enemies will keep trumpeting things even after they have been denied."
Assange said he doesn't know what's behind the accusations "but we have been warned that for example the Pentagon plans to use dirty tricks to spoil things for us."
