MOSCOW (Reuters) - Former U.S. spy agency contractor Edward Snowden has applied for political asylum in Russia, a Russian immigration source close to the matter said on Monday.

The source, who spoke on condition of anonymity, said a Wikileaks activist who is traveling with Snowden handed his application to a Russian consulate in the transit area at Moscow's Sheremetyevo airport late on Sunday.
