The Sumpul River massacre (Spanish: masacre del Sumpul[1]) took place in Chalatenango, El Salvador on May 13, 1980 during the Salvadoran Civil War. Salvadoran Armed Forces and pro-government paramilitaries launched an offensive to disrupt the activities of the Farabundo Martí National Liberation Front (FMLN). The offensive created many refugees who were attacked the next day by the Salvadoran forces. The Honduran military prevented them from fleeing into Honduras, and between 300 and 600 refugees died. Both El Salvador and Honduras denied responsibility for the incident. In 1993, the United Nations Truth Commission described the incident as a serious violation of international law.
