Lists of attacks [note 1] on schools include:
A school shooting is an armed attack at an educational institution, such as a primary school, secondary school, high school or university, involving the use of a firearm. 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, although school shootings take place elsewhere in the world. Especially in the United States, school shootings have sparked a political debate over gun violence, zero tolerance policies, gun rights and gun control.
Mass murder is the violent crime of killing a number of people, typically simultaneously or over a relatively short period of time and in close geographic proximity. A mass murder typically occurs in a single location where one or more persons kill several others.

A murder–suicide is an act where an individual intentionally kills one or more people before killing themselves. The combination of murder and suicide can take various forms:
The Revolutionary People's Liberation Party/Front is a Turkish Marxist–Leninist communist party in Turkey. It was founded in 1978 as Revolutionary Left, and has been involved in a militant campaign against the Republic of Turkey since the 1980s. It was renamed in 1994 after factional infighting. It is classified as a terrorist group by Turkey, the United States, the United Kingdom, the European Union and Japan.
The Frontier Middle School shooting occurred on February 2, 1996, at Frontier Middle School in Moses Lake, Washington, United States. The gunman, 14-year-old Barry Dale Loukaitis, killed his algebra teacher and two students, and held his classmates hostage before a gym coach subdued him.
An active shooter is the perpetrator of an ongoing mass shooting. The term is primarily used to characterize shooters who are targeting victims indiscriminately and at a large scale, who oftentimes, will either commit suicide or intend to be killed by police. More generally, an active perpetrator of a mass murder may be referred to as an active killer.

It has an area of 559 square kilometres (216 sq mi).
A mass shooting is a violent crime in which one or more attackers use a firearm to kill or injure multiple individuals in rapid succession. There is no widely accepted specific definition, and different organizations tracking such incidents use different criteria. Mass shootings are generally characterized by the targeting of victims in a non-combat setting, and thus the term generally excludes gang violence, shootouts and warfare. Mass shootings may be done for personal or psychological reasons, such as by individuals who are deeply disgruntled, seeking notoriety, or are intensely angry at a perceived grievance; though they have also been used as a terrorist tactic, such as when members of an ethnic or religious minority are targeted. The perpetrator of an ongoing mass shooting may be referred to as an active shooter.
In November 2014, two separate terrorist attacks took place in Potiskum in Yobe State, Nigeria. Both incidents involved suicide bombers, killing at least 61 people and injuring scores of others. In both cases, Boko Haram has been accused of carrying out the attacks.
Mass shootings are incidents involving multiple victims of firearm related violence. Definitions vary, with no single, broadly accepted definition. One definition is an act of public firearm violence—excluding gang killings, domestic violence, or terrorist acts sponsored by an organization—in which a shooter kills at least four victims.
