WikiLeaks founder Julian Assange is in urgent need of medical treatment and needs to be allowed to visit a hospital, according to officials at the Ecuadorian Embassy in London.

Assange has been taking refuge in the building since June, in order to avoid extradition to Sweden, where he faces questioning in relation to sexual assault allegations.

He denies those allegations, and says that he is concerned that he could be further extradited from Sweden to the US to face charges connected to the leaking of confidential US government and military information.
