Between 6 and 9 March, Europol, together with the ATLAS network and the European Surveillance Group, coordinated a joint exercise of surveillance and intervention units across the EU. The exercise involved units from Austria, Belgium, France, Germany, Ireland, Luxembourg, the Netherlands, Switzerland and the United Kingdom. Executed in real-life conditions, the coordinated exercise started in Ireland and culminated with several simultaneous interventions in Luxembourg and Maastricht, the Netherlands.
