GAZA CITY, Gaza Strip — Three more Palestinians were killed and hundreds injured when violence broke out again today in the Gaza Strip, even as numerous groups have been calling for the International Criminal Court (ICC) to investigate what they say are Israeli war crimes. However, the court's chief prosecutor believes Hamas might have committed its own war crimes during the confrontations by using civilians as shields.

The ICC is following with "grave concern" the violence during the Palestinians' Great Return March along the Gaza border. In protests that began March 30, demonstrators are demanding implementation of UN Resolution No. 194 of 1948 on Palestinian refugees’ right to return to their homes in Israeli-occupied areas. Since the demonstrations started, around 40 protesters have been killed and thousands have been wounded, as of April 27.

Israel refers to the protests as riots and said demonstrators are throwing firebombs at soldiers. It says protesters have made numerous attempts to breach its border. Hamas' political bureau, on the other hand, says the protesters were unarmed and peaceful. Hamas is one of several groups calling for Israel to be brought to trial.

The Arab League Council called April 3 for the UN Security Council and the General Assembly to form an international commission to look into the shootings.
