Two Russian journalists were arrested by their government on “extremism” charges and ordered by courts to remain in custody pending investigation and trial on accusations of working for a group founded by the late Russian opposition politician Alexei Navalny.

Konstantin Gabov and Sergey Karelin both denied the charges for which they will be detained for a minimum of two months before any trials begin. Each faces a minimum of two years in prison and a maximum of six years for alleged “participation in an extremist organization”, according to Russian courts.
