Mass executions refer to the systematic killing of a large number of individuals, often carried out by governments or military forces. These events can occur during times of war, political upheaval, or as part of genocidal campaigns. The victims are typically targeted based on their ethnicity, political beliefs, or social status. Such actions are considered serious violations of human rights and are condemned by international law. Organizations like the United Nations and Amnesty International work to document and prevent mass executions, advocating for justice and accountability for those responsible.
