and Russian passports were confiscated and she was fined for failing to register her American passport with the authorities.She was detained again last Wednesday on charges of failing to register as a foreign agent.The Justice Ministry in 2017 labeled RFE/RL and several of its affiliates, including Idel.Realii, as “foreign agents” in response to the U.S.
