The attack of the Israel forces on the Palestinian residential tower in the Gaza Strip led to the martyrdom of Taysir al-Jabari and several of his companions. In this paper, in a descriptive and analytical way and with using library sources library the international responsibility of Israel based in the international law rules resulting from the breaching of primary obligation which naturally causes the creation of secondary obligations according to the law of international responsibility has been discussed. In this research by proving the breach of the principle of non-use of force, the international responsibility of Israel has been addressed. In addition, the breach of humanitarian rights is one of the other cases that result in the responsibility of Israel. By breaching the primary obligation and fulfilling the international responsibility, its consequences will be borne by wrongful state. Ceasing and guaranteeing non-repetition as well as compensating damages are among the consequences of the international wrongful act, which is Israel's responsibility. Ceasing and guaranteeing non-repetition in the above case is proven due to Israel's illegal presence in the Gaza Strip. The guarantee of non-repetition can also be investigated due to the fear of repeating the operation. On the other hand, all the material and moral damages caused by Israel during the terror can be compensated.
