MOSCOW, Dec. 13 (Xinhua) -- Russia on Friday called on the international community to remain focused on the problems highlighted by the information made public by former U.S. intelligence contractor Edward Snowden.
The information that the former National Security Agency (NSA) employee leaked could be just a tip of the iceberg, said Russian Foreign Ministry's human rights commissioner, Konstantin Dolgov, in a comment published on the ministry's website.
"This is a positive fact that the impulse triggered by Snowden's revelations hasn't slipped through a crack," he said.
Dolgov cited experts on information security who believed that the U.S. global surveillance has been much more fastidious and wider than Snowden suggested.
According to the NSA, Snowden leaked about 200,000 pieces of classified documents.
In August, Snowden obtained a yearlong residential permit in Russia as a refugee. The status will be canceled once Snowden leaves Russia.
He faces espionage charges in the United States after disclosing a classified intelligence project code-named PRISM.
