KHAN YUNIS, Gaza Strip — For nearly 60 days, no food, fuel, medicine or other item has entered the Gaza Strip, blocked by Israel. Aid groups are running out of food to distribute. Markets are nearly bare. Palestinian families are left struggling to feed their children.

A Palestinian diplomat has told the United Nations’ top court that Israel is killing and displacing civilians and targeting aid workers in Gaza in a “man-made catastrophe of unprecedented proportions.

U.N. and Palestinian representatives at the International Court of Justice accused Israel of breaking international law by refusing to let aid into Gaza, on the first day of hearings about Israel's obligations to facilitate aid deliveries.
