Authorities are investigating what caused a Columbia apartment building to catch fire on Saturday morning.
The Columbia Fire Department responded to Smithton Condo Apartments around 8 a.m. for reports of a fire. Upon arrival, crews saw heavy smoke coming from the building, according to a news release.
The department requested more assistance after receiving reports that people were still inside during the response.
Two people were treated for smoke inhalation, according to CFD. No other injuries were reported.
The news release said an Assistant Fire Marshal was investigating what caused the blaze. No other information was provided.
The release also described the department's response, which included twelve CFD units.
"Crews pulled a preconnected hoseline, advanced it into apartment C and began an aggressive fire attack," the statement said.
It's not clear how much damage was caused by the fire.
