More than 25 years after the end of its civil war, families in El Salvador are still searching for an estimated 3,000 children who disappeared in the fighting. The country's military has so far refused to open its archives from that period to allow an investigation into the whereabouts of children separated from their families. In a decision released in January, El Salvador's Supreme Court backed the demand of Nicolasa Rivas for a probe into the disappearances of her daughters, Gladys Suleyma and Norma Climaco Rivas. Rivas blames the military for taking her daughters. The U.N. Truth Commission created with the signing of the peace agreement in January 1992 estimated there were 5,000 forced disappearances during the war. Human rights advocates have documented about 3,000 more cases and estimate that about 3,000 of all the disappeared were minors. The Supreme Court's decision ordered the armed forces to release information related to a military operation called Mario Azenon Palma." It was during that operation that Gladys and Norma disappeared. The Defense Ministry has said that ... "no documents or registries of any kind related to the alleged operation have been found." The operation's existence has been confirmed by the Inter-American Commission on Human Rights. In its ruling supporting Rivas' call for an investigation into the fate of her daughters, the Supreme Court said there was sufficient information to conclude "they were involuntarily disappeared at the hands of soldiers."
