TOLLESON, Ariz. -- Firefighters are battling a two-alarm fire at a large barn in Tolleson, west of Phoenix.
The fire was reported Monday afternoon, but Tolleson firefighters say it's unclear how the blaze started.
TV news helicopter footage shows flames coming out of the sides of what appears to be a tin barn on a farm near 99th Avenue and Van Buren Street.
Firefighters say a loading dock made of heavy timber also is burning.
Some of the smoke from the fire has wafted eastward and reached the Phoenix metropolitan area.
Firefighters say there are no reported injuries.
They say the barn is complete loss and crews are having difficulty with water supply and access.
They're requesting more pressure from the water company, but power reportedly is out to the booster pumps.
