MADRID.— Cuban anti-terrorist Fernando González thanked supporters in Spain for their solidarity upon his arrival in the country, as an invited guest of the Communist Party of Spain (PCE). González , a member of the Cuban Five who completed his sentence in U.S. prisons in full and is now serving as vice president of the Cuban Friendship Institute, thanked supporters for their efforts and called upon solidarity groups in Spain to continue their work to free Gerardo Hernández, Ramón Labañino and Antonio Guerrero, incarcerated since September, 1998. As part of his visit, Fernando González will meet with the Federation of Cubans Resident in Spain, and participate in meetings with solidarity groups and a concert. René González, another member of the Cuban Five who has completed his sentence, with his spouse Olga Salanueva, concluded a tour of several European countries, September 16 in France. In this nation, he had a busy schedule including meetings with members of Parliament and diplomats from Central America, Mexico and the Caribbean. He had previously visited Portugal and was scheduled to travel to Britain. The British government, however, denied González a visa, for the second time, and Olga was obliged to continue alone, and participate in meetings with legislators and trade unionists in the city of Liverpool.
