Some 135 firemen and 45 fire extinguishing units, including a firefighting train, have been deployed to the scene of a huge fire at a massive chemical plant in Ufa, according to local officials.
Neither injuries nor deaths have been reported so far; technicians have found no traces of noxious substances in the air close to the nearest residential buildings.
According to the preliminary data, the fire was due to a technical issue: an anti-corrosive agent used for pipe manufacturing became overheated.
