Assange, who has enraged the United States by leaking US diplomatic cables that embarrassed world leaders, has said his site has been losing almost half a million euros (650,000 dollars) a week since those leaks began.

“We cannot survive the way things are going,” he told the French radio station Europe 1, complaining that the organisation's ability to garner online donations has been blocked. But he vowed Wikileaks would fight back. In a separate interview with France Info radio, he said Wikileaks aimed to continue leaking documents.

Assange was speaking from Britain, where he is on bail facing possible extradition to Sweden for questioning on allegations of sexual assault. A court hearing was due later Tuesday to set a date for his trial.

The Wikileaks website was blocked after it began leaking its flood of cables, but soon sprang up again in various countries.

“The organisation is being attacked but it is growing quite quickly,”Assange told Europe 1.

In an interview published Monday in Swiss newspapers, Assange said Wikileaks was losing more than 480,000 euros since it started publishing the diplomatic cables.

“To continue our business, we would need to find a way or other to get this money back,” he said.

He did not explain exactly how Wikileaks was losing so much money with the website, but several banks or payment systems have reportedly stopped doing business with it.

“I would say that the pressure reinforces my determination,” he said in the Swiss interview. “But from a financial point of view, it's another matter.”
