Three people, including two young girls, were killed when two school buses crashed in Knoxville, Tennessee, officials said Tuesday.
Knoxville Police Chief David Rausch told reporters the children on the bus were in kindergarten through third grade. An female aide on one bus was killed in the accident, which occurred at about 3 p.m.
"(My grandson) was in shock. He was crying. He was petrified," Gloria Johnson told CNN Knoxville affiliate WVLT. "A bus is supposed to be safer than a car."
At least 23 injured children were taken to hospitals. Some were transported by emergency vehicles; some were driven by their parents, the chief said. One hospital said 20 children were treated there and released.
