International humanitarian law
Human Rights Watch stated that armed Palestinian groups fired hundreds of rockets at Israeli cities, violating international humanitarian law, and that statements by Palestinian groups that they deliberately targeted Israeli civilians demonstrated an "intent to commit war crimes." HRW's Middle East director Sarah Leah Whitson said that Palestinian groups made clear that "harming civilians was their aim" and said that the launching rockets at populated areas had no legal justification. International humanitarian law prohibits deliberate attacks on civilians, and intentional violations can be war crimes.
