Russia threatens to jail Putin critic Navalny if he does not return immediately

• An investigation by the website Bellingcat found this month that Navalny was tailed by a chemical weapons team from Russia's Federal Security Service (FSB) before his poisoning.
• Last week, it was revealed that Navalny had duped one of the FSB agents accused of tailing him into detailing on a phone call how the botched operation was carried out. The Kremlin has denied having any role in the poisoning and claims it hasn't seen evidence Navalny was poisoned.

Details: The Federal Prison Service (FSIN) on Monday accused Navalny of violating the terms of a suspended prison term he has been serving since 2014 for a theft case he claims was politically motivated.

• Navalny's lawyer said there is no way he can return to Moscow by Tuesday and accused the FSIN of acting on the orders of the Kremlin, per Reuters.
• Navalny has been arrested several times for his anti-government protests. His probation period expires on Dec. 30.
