German TV issued a further snippet ahead of a broadcast late Sunday in Europe of an exclusive interview with Snowden in which the intelligence whistleblower claims that US officials wanted him killed.
"These people, and they are government officials, have said they would love to put a bullet in my head or poison me when I come out of the supermarket, and then watch as I die in the shower," he told interviewer Hubert Seipel, who said the interview took place last Thursday.
Snowden, who was granted temporary asylum in Russia in August, referred in the interview to a report by US website BuzzFeed of explicit threats against him from unnamed Pentagon and National Security Agency (NSA) officials.
The former NSA contractor is wanted by US authorities on treason charges for disclosing details of a vast intelligence operation that monitored millions of phone calls and emails across the world.
The interview was aired on German ARD television, of which NDR is a member, with a German-language voice-over late on Sunday, European time.
In the ARD talkshow Günter Jauch run prior to the interview's broadcast, former US ambassador to Berlin John Kornblum was asked where Snowden would be in 10 years time.
Kornblum said he expected Snowden would return to the United States under a deal. "I believe there will be an arrangment," Kornblum said.
