An Air Force Base near Tucson has stepped up security and limited traffic into and out of the base because of an unspecified security situation.
A Davis-Monthan Air Force Base spokesperson could not confirm
reports of gunfire on the base or say if anyone has been shot.
Senior Airman Timothy Dunaway says traffic has been reduced to a
single point entry but he refused to elaborate.
He says the Sonoran Science Academy on the base is on lockdown.
KVOA-TV says the kids are safe on the base.
Davis-Monthan is adjacent to the Pima Air & Space Museum and the
"boneyard" for old military and government airplanes that is a
popular destination for aviation enthusiasts.
