Why isn’t desperately needed aid reaching Palestinians in Gaza?

From the earliest days of the Israel-Hamas war, the United States and much of the international community have pressed Israel to allow more humanitarian aid into the Gaza Strip. United Nations agencies and aid groups say the ongoing hostilities, the Israeli military's refusal to facilitate deliveries and the breakdown of order inside Gaza make it increasingly difficult to bring vital aid to much of the coastal enclave. The World Food Program said Tuesday it has paused food deliveries to isolated northern Gaza, where the U.N. children’s agency says one in six children are acutely malnourished.
