TOPEKA, Kan. (AP) — Authorities say two people are hospitalized after a Topeka apartment fire.

The Topeka Capital-Journal reports that heavy smoke was coming from the east side of the 12-unit building when crews responded around 12:30 a.m. Wednesday.

Firefighters conducted a search and removed two adults from the building. Fire officials said they were taken to a Topeka hospital and later transferred to The University of Kansas University Hospital in Kansas City, Kansas. Their injuries aren’t believed to be life-threatening.

The fire was classified as accidental and blamed on improperly discarded smoking materials. Damages to the three-story building and its contents are estimated at $150,000.
