The fire, some 250 meters (880 feet) above street-level, was believed to have started when plastic sheeting came in contact with a spotlight illuminating a work area, Nikita Zhuravlev, a representative of project developer Potok8, told Associated Press Television News. He said a firefighting helicopter appeared to have spread the flames by flying too low over the fire.
