There has been no information about the whereabouts of Ruslan Nakhushev for three days now. His mobile phone is not answering. The employees of the Elbrus military foundation, which is headed by Nakhushev, also know nothing. But it is known for certain that last Friday he was summoned for questioning by the FSB in Nalchik. According to some sources, the subject of the conversation was information about employees of the Institute of Islamic Studies Musa Mukozhoev and Anzor Astemirov, whom the authorities suspect of organizing the attack on Nalchik on October 13.
