Guardian: The WikiLeaks founder, Julian Assange, is tonight facing growing legal problems around the world, with the US announcing that it was investigating whether he had violated its espionage laws. Friends said that Assange was in a buoyant mood, however, despite the palpable fury emanating from Washington over the decision by WikiLeaks to start publishing more than a quarter of a million mainly classified US cables. He was said to be at a secret location somewhere outside London, along with fellow hackers and WikiLeaks enthusiasts. In contrast to previous WikiLeaks releases, Assange has, on this occasion, kept a relatively low profile. His attempt to give an interview to Sky News via Skype was thwarted today by a faulty internet connection.
