According to the Emergency Situations Ministry, the fire has spread over 4,000 square meters of space, and the blaze engulfed all the floors of the building and had the roof collapse.
It added that a helicopter was set to take off to extinguish the fire, which spread to a neighbouring industrial building, a correspondent reported. The Russian Defence Ministry has deployed two Mi-8 helicopters to help extinguish the blaze. In the meantime, the prosecutor's office of the St. Petersburg's Nevsky district has launched an investigation into the incident. According to the Unified State Real Estate Register, the type of permitted use of the land plot under the fire-hit 19th-century building allows high-rise buildings to be erected there.
