Shocking video shows a bull slowly being killed in front of cheering children as young as 6 at a bullfighting school.

European animal rights group One Voice infiltrated a French bullfighting school as part of the group’s push to ban the centers that it says only give an “education of sadism.”

The group produced disturbing video of the children watching as bulls are teased and ultimately killed, with one shown getting gored in the back of the head after collapsing, soaked in blood.

“One can start at the age of 6 to attend these schools,” One Voice said as part of its report, with footage showing one young boy, clearly under 10, looking terrified as he is pulled toward a bull by an older man.

“They learn that torturing a living animal by planting spears and then pushing a blade into its body is acceptable and expected,” the group said, saying psychologists worry about the impact such bloodshed will have.

“Ban these schools,” One Voice pleaded.
