Brussels is a hotspot for intelligence activities. Potential espionage targets are abound. Belgium's capital city not only hosts the NATO headquarters and the European institutions –Council, Commission and Parliament. Also multinationals, the International Trade Union Confederation, the World Customs Organisation and the European Economic Area are headquartered in Brussels.
Next to that come Eurocontrol, SWIFT, the European Aviation Safety Agency, the Western European Union and up to 2500 international agencies , 2000 international companies and 150 international law firms.
Also radical networks, secessionist movements, high technological research centers and migrant communities –Turkish, Moroccan, Congolese, Rwandese– are among the potential targets of foreign espionage.
