Firefighters in Buffalo continue to battle a stubborn blaze at a plant that manufactures industrial lubricants.
Buffalo media outlets report that the fire started before 6 a.m. Wednesday at the Niagara Lubricant Co. in the city's Black Rock neighborhood.
Thick black smoke spewed from the three-story structure several hours after the fire started. Several explosions were heard inside the building.
Crews were ordered out of the building and were fighting the fire from outside. Fire officials called for help from a Buffalo Niagara International Airport foam truck and told nearby residents to close their windows and doors.
Niagara Lubricant's website says the nearly 90-year-old company makes and packages lubricating oils, greases, industrial oils and tire care products.
There are no reports of injuries or a possible cause of the fire.
