Translated by Ollie Richardson & Angelina Siard 16:35:03 04/04/2017 NSN.fm The former head of the anti-terrorist unit of the FSB Aleksandr Gusak in an interview to NSN paid attention to the fact that the St. Petersburg security services could not prevent the explosions in the subway on the day of the arrival of Vladimir Putin. “If it was so that the person put the device in a bag and then switched into another carriage, then it was radio-controlled bombs. They work through wi-fi, the person presses the button and there is an explosion. They also could put the [explosive] devices into a depot,” said Gusak to NSN. According to the former head of the anti-terrorist unit of the FSB, the connection between the explosion and the arrival of Putin to the city is obvious. Aleksandr Gusak admitted to NSN that he is surprised by the fact that the employees of the relevant authorities “did not have enough brains” to carry out large-scale preventative work prior to the President’s visit. It should be added that a group of skilled investigators and criminalists from the central office of the Investigative Committee were sent to St. Petersburg. The governor of St. Petersburg Georgy Poltavchenko expressed condolences to the families of the deceased and injured in the subway. The governor noted that the city government will give all necessary help to the families of the victims of the terrorist attack. A three-day mourning period was declared from 04.04.17 in St. Petersburg. Copyright © 2017. All Rights Reserved.
