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 in 1983 , the assassination of a Palestine Liberation Organization representative at a Socialist International conference also in 1983 , and a number of domestic terrorist attacks , the Portuguese government became convinced of the need for a new intelligence agency . This led to the establishment of SIRP in 1984
