By region -- Europe
The following is a list of incidents of shootings that occurred at schools in Europe .
A school shooting is an attack at an educational institution, such as a primary school, secondary school, or university, involving the use of firearms. Many school shootings are also categorized as mass shootings due to multiple casualties. The phenomenon is most widespread in the United States, which has the highest number of school-related shootings, but school shootings have taken place in many countries across the world. According to studies, factors behind school shooting include family dysfunction, lack of family supervision, mental illness among many other psychological issues. Among the topmost motives of attackers were: bullying/persecution/threatened (75%) and revenge (61%), while 54% reported having numerous reasons. The remaining motives included an attempt to solve a problem (34%), suicide or depression (27%), and seeking attention or recognition (24%). School shootings have sparked a political debate over gun violence, zero tolerance policies, gun rights and gun control.
