Former CIA employee Edward Snowden may leave the transit zone of Moscow's Sheremetyevo Airport within the next few days, lawyer Anatoly Kucherena, who has been providing legal advice to Snowden, told Interfax on Wednesday.

"The granting of temporary asylum to him will take no longer than one week. I think he will be able to leave Sheremetyevo's transit zone within the next few days," Kucherena said.
