Nearly 200 hemeless people were relocated after a fire forced them out of a downtown building Tuesday afternoon.
"It's heavy damage up there on that top floor and on the roof area. It breached the windows, so there was smoke and everything pouring into the building. We shut off the utilities," Pittsburgh Bureau of Fire Chief Darryl Jones told KDKA.
Four firefighters were hurt, three of whom went to the hospital. Two civilians also were transported for heat-related issues, the chief said.
The fire started on the roof in an air conditioning unit. The dark smoke was visible throughout the area.
The homeless were relocated to the convention center.
