OREGON CITY, Ore. (AP) — A fire district spokesman says at least two firefighters were knocked backward by flames as they battled a three-alarm fire at an Oregon City, Oregon, strip mall.

Clackamas Fire District 1 spokesman Brandon Paxton says that thanks to their protective suits, the firefighters suffered just minor injuries Wednesday.

The Oregonian reports (http://is.gd/5jCI6f ) that crews had pushed through a door, allowing fresh oxygen to rush in and stoke the flames.
