Rights activists are marking the 30th anniversary of one of the worst massacres of El Salvador's civil war.
The groups say they are still awaiting justice three decades after an army battalion swept through the township of El Mozote during a counterinsurgency campaign, slaughtering about 1,000 people before tossing many of their bodies into a church and burning it. The killings took place Dec. 11-13, 1981.
The Center for International Law and Justice says it hopes the Costa Rica-based Inter-American Court of Human Rights will hear the case next year.
Some of the alleged perpetrators have died. Before that, they were covered by an amnesty law.
The war between leftist rebels and an authoritarian government claimed 75,000 lives.
