Even before the first phase is completed, the fragile cease-fire agreement that has paused 15 months of war in Gaza between Israel and Hamas faces increasingly long odds of lasting or even reaching phase two.

Hundreds of truckloads of food, fuel and other supplies have arrived in Gaza each day since the cease-fire took effect. But the need is vast after 15 months of war.

More than 4,200 aid trucks have entered the Gaza Strip in the six days since a ceasefire began between Israel and Palestinian militants Hamas, the United Nations said, although there was a large drop in the number of loads delivered on Friday.
