斯诺登在莫斯科机场同人权活动人士会晤

Former U.S. intelligence contractor Edward Snowden is meeting Friday with human rights groups and Russian lawyers at a Moscow airport to talk about what he says is "threatening behavior" by the United States to keep him from gaining asylum.

The head of the Russian office of Amnesty International, Sergei Nikitin, said he would attend the meeting in the airport's transit area, where Snowden has been staying for nearly three weeks.  A representative of Human Rights Watch also said she would go, and posted a Facebook message in which Snowden accused the U.S. of waging "an unlawful campaign" to deny him the right to seek asylum.

Three Latin American countries -- Venezuela, Bolivia and Nicaragua -- have offered the 30-year-old Snowden asylum.  But getting there may prove difficult, as the U.S. has revoked his passport.

Snowden said he plans to talk with the group he is meeting with about the "next steps forward in my situation."  He has not been seen publicly since he arrived at Sheremetyevo airport after a flight from Hong Kong.

The U.S. wants him extradited to stand trial on espionage charges, after he leaked details of surveillance programs conducted by the clandestine U.S. National Security Agency.  Russia has refused to release him to U.S. custody, while urging him to depart for another country.
