The number of Europeans who left to fight in Syria is estimated to range between 5,000 and 6,000, among them 1,450 from France, according to the European Commissioner for Justice Vera Jourova. She added that there were fears that the numbers were "significantly undervalued." The European Commissioner said most Europeans who desired to join or have already joined the ranks of militant groups in Syria "do not have religious motives, but (go) mainly because of boredom and in the search for adventure."
