Terrorist attack, suspected Russian subway security deposit loopholes!

A terrorist attack on the Russian subway was initially suspected to be a loophole in the subway security system. On the afternoon of April 3, in Russia, a subway from St. Petersburg's [Hay Square Station" to [Technology College-1 Station" exploded, and the explosion was located in the third carriage of the subway. The explosion was caused by a small homemade device with an explosion equivalent of about 200-300 grams of TNT, including destructive items such as steel nails. After the explosion, various government departments in Russia responded quickly and rescuers arrived at the scene five minutes after the incident. Local time 15:00: The Russian National Counter-Terrorism Committee stated that a kilogram of shougongzhadan disguised as a fire extinguisher was discovered and destroyed at the St. Petersburg Uprising Square subway station. Local time 15:40: All subway stations are closed. Local time 15:53: The subway station evacuation work is all over.
Russian President Vladimir Putin is preparing to hold talks with Belarus`s overall Lukashenko at the time of the explosion. He quickly responded that the relevant authorities have launched a comprehensive investigation on the matter. Two hours after the incident, the Russian Attorney General`s Office declared the St. Petersburg subway bombing as a terrorist attack. At present, the cause of the incident is still under investigation.
According to the Russian "Rambler" news network, Sergei Goncharov, president of the Russian "Alpha" anti-terrorist army veteran association, said in a live broadcast of "Russian 24" that Russian President Vladimir Putin is inspecting in St. Petersburg during the St. Petersburg subway terrorist attack. This is no coincidence. On the day of the explosion, Russian President Vladimir Putin met with Belarusian President Alexander Lukashenko in St. Petersburg and participated in the [Truth and Justice" media forum. So how did the terrorists bring the bomb into the subway? Investigations by relevant departments found that the security system problem of the St. Petersburg Metro had already existed very early: before 2016, all the subway stations were only guarded by the police and did not have any security facilities. In 2013, the St. Petersburg Metro Company announced that it will invest 5.9 billion rubles to renovate security equipment and monitoring systems for all subway stations. It is planned that by 2015 all passengers must pass through security gates, security inspection machines and metal detectors to enter the subway station. The installation of safety equipment systems and training staff in the halls of 73 subway stations have cost more than 2 billion rubles in the past two years. The main equipment supplier is Moscow CHT, which is also responsible for the security system setup of the Moscow Metro.
The head of the company, Dmitry Bassaf, insists that the security equipment they provide is safe and reliable. He does not know how the terrorists brought the bombs into the subway station. He said that this may be caused by human factors. According to the working guidelines, there should be 5 staff members in each subway station hall to cooperate with the safety inspection, but often there are only 1-2 staff members in the hall. When many people enter the hall at the same time, the security inspection work cannot be carried out. .
According to RIA Novosti, it is possible for terrorists to verify the security system in St. Petersburg several times before. In March of this year, the emergency department closed the subway station at least five times due to the discovery of unknown objects. Just on April 3, six hours before the tragedy, a similar situation occurred at the Heihe Station. The subway station was closed for nearly an hour. Shortly before the explosion, the "Uprising Square" station was also closed due to the discovery of unknown objects. In the future, it is necessary to further improve the construction of security inspection equipment and systems to prevent such incidents from happening!
