Because of the memory of the abuses of the PIDE/DGS in supporting the regime , the establishment of a new civilian intelligence agency was delayed for more than a decade . However , following a terrorist attack on the Embassy of Turkey , the assassination of a Palestine Liberation Organization representative at a Socialist International conference in 1983 , and a number of domestic terrorist attacks by isolated far-left and far-right groups , the Portuguese government became convinced of the need for a new intelligence agency . This led to the establishment of the Sistema de Informações da República Portuguesa ( SIRP , Intelligence System of the Portuguese Republic ) in 1984
