The office of the Nationaal Coördinator Terrorismebestrijding (NCTb) or counter-terrorism coordinator was set up by the government in 2004. Its job is to oversee the 20 or so different organisations involved in combating terrorism in Holland, ranging from the secret service to the immigration department. Every so often the NCTb announces what terrorism alert the Netherlands is currently operating under – minimal, limited, substantial or critical. The agency also analyses intelligence and draws up policy.
