(CNN) -- A Phoenix, Arizona, elementary school bus careened out of control for nearly a mile Wednesday evening, causing more than a dozen accidents and sending at least 26 people to the hospital.
A Phoenix, Arizona, school bus crossed over several lanes of traffic, crashing into several vehicles on Wednesday.
Phoenix police officer James Holmes told CNN the bus struck two cars at an intersection as it approached an overpass on Interstate 10. The bus later crossed into oncoming lanes, causing a chain reaction of collisions.
At least two cars overturned, and several passengers in the vehicles had to be cut out of the wreckage, authorities said.
Holmes said the bus carrying 45 students came to a stop a mile from the first accident scene. He said panicked children began jumping from the bus and fled into the neighborhood. Watch children describe frenzy of being on out-of-control bus »
Officers had to round up the students and used media reports to ask for help in looking for them. By late Wednesday, police thought they had located everyone. No injuries were reported to any of the children on board.
Police were interviewing the driver, trying to determine what caused the accident. CNN affiliate KPNX reports the bus driver lost consciousness before the crash.
Twenty-six passengers in the other cars, including several children, were being treated at hospitals. Some of the injuries were serious, but none was thought to be life-threatening.
