On the night of 12/13 May 1984, around 2 o'clock in the morning, during the Oesling NATO Military Exercise, the so called Vielsalm Incident took place. The Vielsalm station in Belgium was attacked and a guard was shot several times, but miraculously survived. A large quantity of arms were stolen. Later some of these arms ended up in the hands of the French terrorist group Action Directe, and the Belgian terrorist group Les Cellules Communistes Combattantes. The identity of the attackers remains a total mystery.
