Explosion at Colo. middle school causes injuries

ERIE, Colo. (AP) - August 1, 2012

Mountain View fire spokeswoman Laura McConnell says multiple injuries have been reported at Erie Middle School, but there are no details on the extent.

The Daily Camera reports that three contractors were injured in the explosion. A school district spokesman told the newspaper the explosion may have been caused by a hot water heater.

Students aren't set to return to class until Aug. 16.

Erie is about 14 miles northeast of Boulder.
