Death squads in El Salvador

Death squads in El Salvador (Spanish: escuadrones de la muerte) were far-right paramilitary groups acting in opposition to Marxist–Leninist guerrilla forces, most notably of the Farabundo Martí National Liberation Front (FMLN), and their allies among the civilian population before, during, and after the Salvadoran Civil War. The death squads committed the vast majority of the murders and massacres during the civil war from 1979 to 1992 and were heavily aligned with the United States-backed government.
