Russian authorities intensify crackdown on Navalny's allies and lawyers

Investigators have searched the homes of three of Alexei Navalny's lawyers on suspicion of involvement in an "extremist community".
The searches are seen as attempts to further isolate Navalny, who is currently imprisoned in a penal colony.
Navalny is due to be moved to a different "special regime" colony after being convicted of "extremist" activity in August.
Navalny's lawyers may face up to six years in prison if found guilty of belonging to an extremist group.
The investigations are viewed as acts of intimidation to isolate Navalny and his associates.
