The United Nations is facing difficulties in delivering aid to the Gaza Strip, with significant checkpoint delays and denied requests for aid deliveries. Despite some improvements in coordination with Israel, challenges persist in scaling up aid distribution. The humanitarian crisis in Gaza has escalated, leading to increased global outrage. Israel has approved reopening crossings and ports for aid delivery after pressure from U.S. President Joe Biden. The focus is on improving access to essential services like water, sanitation, and health to prevent famine. U.S. officials acknowledge progress in aid delivery but are working to further improve the situation. Israel is retaliating against Hamas in Gaza following an attack, resulting in casualties on both sides.
