This is the deliberate bombing of a trapped population who have nowhere to flee. Gaza has been an open-air prison for nearly two decades and is fast becoming a mass grave. 40% of those killed are innocent children. Whole families are being murdered. While the world watches and with the active support of many governments, millions of Palestinian civilians - children, women, families - are being collectively punished and dehumanized, all while being deprived food, medicine and humanitarian aid against international law. By refusing to demand a humanitarian ceasefire and blocking the UN Security Council from imposing one on both parties, world leaders are complicit in these crimes.
