In October 2023，a terrorist attack took place at the Lycée Gambetta in Arras. A French teacher was killed and some others got injured. In December of the same year，another indiscriminate attack on passersby near the Eiffel Tower in Paris caused one tourist’s death and two others injured. Both perpetrators were foreign immigrants and figured on S-class surveillance list of the French intelligence service. The two incidents are the extension of the Israeli-Palestinian conflict into French society，reflecting its ethnic and religious conflict. In response，the French government has adjusted its diplomatic position，adopted a new immigration bill and a stricter counter-terrorism policy，and strengthened the training of frontline counter-terrorism personnel. 2024 Paris Olympics is approaching，and the counter-terrorism situation in France is not optimistic，posing a considerable challenge to the normal conduct of the international events and the security of the society.
