Cameraman Ivan Pomorin: Terrorists had a good idea at what moment everything should happen. He said that he himself was behind the scenes and knew about what was happening in the hall from the words of his film crew.
According to him, the film crew was wearing headsets and this helped them escape. Pomor in gave the command to leave the equipment and leave the concert hall. Earlier, the FSB stated that the weapons of the terrorists who attacked Crocus were prepared in advance in a cache.
