At least three people were killed Saturday after a vehicle crashed into a Pittsburgh plasma clinic, according to authorities.
The car struck the Biomat USA clinic a little after 11:30 a.m. ET, Pittsburgh Public Safety Director Wendell Hissrich told NBC affiliate WPXI at the scene.

He also said that one person was in critical condition and a paramedic was treated for smoke inhalation. A third person was injured in the incident, but that person's status was unknown.
The names of the victims were not released.
The crash, meanwhile, caused a small fire in the building, and firefighters are attempting to put it out.
