Julian Assange, in an interview with ABC television, was asked to respond to recent remarks by US Secretary of State John Kerry that people could die as a consequence of explosive revelations by Snowden, the fugitive former National Security Agency contractor who blew the lid on vast US phone and Internet surveillance programs. Other US officials have repeatedly made the same assertion.
"We have heard this rhetoric. I myself was subject to precisely this rhetoric two, three years ago. And it all proved to be false," Assange said.
"And the revelations by Snowden, these are even more abstract."
Assange spoke from the Ecuadoran embassy in London where he has been holed up for a year to avoid being sent to Sweden. He is wanted there for questioning linked to rape allegations.

In the ABC interview, Assange called Snowden a "hero" and said it was "not acceptable" that US Vice President Joe Biden personally called Ecuadoran President Rafael Correa Friday to "pressure" him to reject Snowden's asylum request.
The Australian also suggested more Snowden leaks were forthcoming.
"There is no stopping the publishing process at this stage," Assange said. "Great care has been taken to make sure that Mr. Snowden can't be pressured by any state to stop the publication process.
