In this document, the US Ambassador to Argentina reports on the return to Uruguay of PVP militants exiled in Argentina. According to the UNHCR, 12 out of 14 of the names on the list refer to Uruguayan refugees kidnapped in July and September 1976 and at least 40 more Uruguayans were disappeared during this period. The US Ambassador contends that the evidence and reports available to the Embassy convincingly show that the kidnappings of Uruguayan refugees in July and September were carried out by Uruguayan and Argentine security forces, acting clandestinely and in cooperation.
