Israel’s bombardment of Gaza has entered its fourth month as the United Nations’ top humanitarian official warns the relentless assault has left Gaza uninhabitable. According to Palestinian health officials, the death toll in Gaza has topped 23,000, including almost 10,000 children. U.N. emergency relief chief Martin Griffiths said Gaza has become a “place of death and despair.” He said Gaza is on the verge of famine as it faces the “highest levels of food insecurity ever recorded.”
