13 in Moscow on accusations of participating in “extremist” activities for passing on letters written by Navalny in prison to his associates.Navalny and his allies have called the lawyers’ arrests an attempt to further isolate him.Those on the “extremists and terrorists” registry have their Russian bank accounts frozen.Rosfinmonitoring’s searchable database of groups and persons with links to terrorist activities includes al-Qaeda, the Taliban and the Islamic State.In August, a court increased Navalny’s sentence to 19 years on charges of creating an “extremist” organization. He has accused officials at the penal colony where he is held of withholding letters from his wife Yulia Navalnaya.
