Brazil-based US reporter Glenn Greenwald said Wednesday he would publish documents from intelligence leaker Edward Snowden focused on France and Spain.
Greenwald, a Rio-based correspondent for Britain's Guardian
newspaper, also said that if Brazil wanted more data on alleged US snooping into its affairs it should offer Snowden asylum.
Snowden, a former US spy agency contractor wanted by Washington, is currently at an unknown location in Russia after Moscow granted him temporary asylum.
Brazil did not respond to a Snowden request for asylum as he sought refuge following his first explosive disclosures detailing the US government's digital dragnet.
Testifying before a Brazilian congressional panel, Greenwald accused Washington and its allies of waging a "war against journalism and the process of transparency."
"I am learning now that the United States is using this surveillance system to punish the journalistic process," said Greenwald, who, without elaborating, added he was working on material relating to France and Spain.
"We are undertaking high-risk journalism. We shall continue doing so until we publish the last document I have," Greenwald told senators investigating allegations that Washington spied on Brasilia.
"I am not holding onto relevant documents nor hiding information. All that I had regarding surveillance against Brazil, and now France - I am working with French and Spanish newspapers - I publish. I don't hold onto it," he said in Portuguese.
Greenwald said governments, including Brazil's, appeared to be grateful for the disclosure of alleged US spying on them "but they are not disposed to protect the person who passes on the data."
