United States intelligence leaker Edward Snowden has accused President Barack Obama of denying him his right to asylum, in a statement, a first since flying to Russia on June 23, published by Wikileaks.

"On Thursday, President Obama declared before the world that he would not permit any diplomatic "wheeling and dealing" over my case. Yet now it is being reported that after promising not to do so, the President ordered his Vice President to pressure the leaders of nations from which I have requested protection to deny my asylum petitions," he said.

"This kind of deception from a world leader is not justice, and neither is the extralegal penalty of exile. These are the old, bad tools of political aggression. Their purpose is to frighten, not me, but those who would come after me," he added.

Snowden has applied for Aslyum in Russia. The former Central Investigation Agency analyst, who is holed up in a Moscow airport hotel, is wanted by the US on charges of espionage.
