over 2,500 and operated at all levels of the new Nicaraguan government. Sandinista defector Álvaro Baldizón confirmed that Cuban influence in Nicaragua's Interior Ministry (MINT) was more extensive than was widely believed at the time, and Cuban "advice" and "observations" were treated as though they were orders. Puerto Rico The DI sought to aid the growing Puerto Rican separatist movement. Dr. Daniel James testified before a U.S. Senate subcommittee that the DGI, working through Filiberto Ojeda Ríos, organized and trained the Fuerzas Armadas de Liberación Nacional Puertorriqueña (FALN) in 1974. In October 1974, Ojeda was arrested and charged with terrorist acts against American hotels in Puerto Rico. Authorities found a substantial amount of Cuban government documents and secret codes in his possession. Shortly after his release on bail he disappeared but was credited with the 1979 unification of Puerto Rico's five principal terrorist groups into the Cuban-directed National Revolutionary Command (CRN). According to the former chief investigator of the U.S. Senate, Alfonso Tarabochia, the DGI began directing criminal activities in Puerto Rico and the eastern and midwestern United States as early as 1974. That June the secretary general of the Puerto Rican Socialist Party, Juan Marí Bras, met in Havana with Fidel Castro to consolidate party solidarity. Beginning in September 1974, the incidence of bombings by Puerto Rican extremists, particularly the FALN, escalated sharply. Targets included U.S. companies and public places. The FALN was responsible for a bombing that killed four and wounded dozens at the historic Fraunces Tavern in lower Manhattan on January 25, 1975. Later that year, Fidel Castro sponsored the First World Solidarity Conference for the Independence of Puerto Rico in Havana. Ríos was killed by the FBI on Friday, September 23, 2005, in the town of Hormigueros, Puerto Rico. Camp Matanzas Camp Matanzas is a training facility operated by the DI and is located outside Havana since early 1962. It has hosted the likes of Carlos the Jackal.
