Head of the 1st Administration of the Ministry of the Interior Josef Houska reports a complaint by the Brazilian government regarding to Czechoslovak assistance of transporting guerrilla fighters from Cuba to Latin America. Brazilian government issued an official warning that relations between Brazil and Czechoslovak could be deteriorated in connection with the support for Cuba. Houska says Brazilian officials' argument could be proof that Czechoslovak specially selected officials making technical arrangement for the transits belong to some section of the Czechoslovak civil service. However, the Czechoslovak authorities cannot be blamed that they go along with the activities of the Cuban Embassy in Prague, which controls the transport of the guerrillas since an embassy is entitled to engage in full diplomatic activities in a friendly country. Houska argues that the Brazilian government does not have conceret evidence for the direct accusation of Czechoslovakia. The position of the Brazilian Ministry of Foreign Affairs could have been the result of pressure by ultra-reactionary forces in domestic policy which are concerned by the opposition activities in Brazil and abroad.
