The WikiLeaks founder Julian Assange has denied speculation that the American NSA whistleblower Edward Snowden was interrogated by Russian authorities.

30-year-old Snowden was granted one year's asylum by the Kremlin at the start of August after spending more than a month in hiding in the transit area of Moscow Airport. Snowden's lawyer has said the temporary asylum could be renewed on an annual basis. 

Julian Assange says WikiLeaks has had someone by Snowden's side throughout his time in Moscow and that Russian authorities have "behaved well".

Assange, who has been unable to leave the Ecuadorian embassy in London for over a year, also hinted that his website may soon leak more information from Snowden in the near future.
