The news site "RBC" reported that "prominent Kremlin opposition figure Igor Girkin has been placed under arrest until September 18." Official news agencies indicated that "investigators from the Russian Federal Security Service (FSB) requested a Moscow court today, Friday, to detain the nationalist opposition figure Igor Girkin on charges of inciting extremist activities." The TASS agency and Russian Media Agency stated that "Girkin could face up to five years in prison if convicted." This action suggests that authorities have grown tired of his criticism of what Russia calls a "special military operation" in Ukraine.
