International humanitarian law
Rocket attacks by Hamas have been condemned by human rights organizations as war crimes, both because they usually take aim at civilians and because the weapons' inaccuracy would disproportionately endanger civilians even if military targets were chosen. After Operation Pillar of Defense, 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 launching rockets at populated areas had no legal justification. International humanitarian law prohibits deliberate attacks on civilians and intentional violations can be war crimes.
