'Snowden has not entered Russia', says Lavrov

Russian Foreign Minister Sergei Lavrov says fugitive US intelligence leaker Edward Snowden has not entered Russia.

He criticised what he termed US attempts to blame Russia for his disappearance, saying they were "groundless and unacceptable".

The exact whereabouts of Mr Snowden, who is thought to have flown to Moscow from Hong Kong on Sunday, are unclear.
