A lawyer for imprisoned Russian opposition leader Alexei Navalny, who has complained of serious back and leg pain in custody, says doctors have found him to be suffering from a double hernia.

Olga Mikhailova told the independent TV channel Dozhd that Mr Navalny also is beginning to lose sensation in his hands.
