TEHRAN, Jan. 21 (MNA) – One year has past the day when the Plasco building, a 17-story steel high-rise in Tehran, caught fire. The blaze began on one of the building’s upper floors and then spread quickly through the tower’s sprinkler-less garment workshops. As the fire department battled the nearly unreachable fire, the steel skyscraper collapsed in full view of Iranian state television cameras, burying sixteen firefighters and at least six civilians.
