MINNEAPOLIS (AP) — Dozens of Minneapolis firefighters were called out to a fire that burned a warehouse at a lumberyard.

Battalion Chief Stephen Dziedzic says about 35 firefighters responded to Shaw Stewart Lumber in northeast Minneapolis late Saturday night after a passer-by reported the blaze.

No injuries were reported as of early Sunday. Dziedzic says no one was believed to be at the locked-up lumberyard at the time.

The Star Tribune

reports most of the one-story warehouse collapsed, but firefighters were able to save other buildings on the property.

Fire crews remained on the scene Sunday to extinguish hot spots and investigate the cause.
