Snowden, who is believed to have been staying at the Moscow airport transit zone since June 23, applied for temporary asylum in Russia last week. The United States wants him sent home to face prosecution for espionage.
Asked by a reporter whether the government's position had changed, Dmitry Peskov told Russian news agencies that "Russia has never extradited anyone and never will." There is no US-Russia extradition treaty.
Peskov also said that Putin is not involved in reviewing Snowden's application or discussions of the ex-NSA contractor's future with the US, though the Russian Security Service, the FSB, had been in touch with the FBI.
