The aid lifeline for Umm Muhammad and hundreds of thousands of other Palestinians is now under existential threat as Israel lays siege to Gaza once again.

The UN’s food agency has warned that it will run out of supplies to help feed Palestinians in Gaza in just two weeks if Israel continues its total blockade of food and other necessities, putting the lives of millions of Palestinians at risk.

The U.N. food agency says it only has enough food supplies in the Gaza Strip to keep public kitchens and bakeries open for less than two weeks, after Israel halted the entry of food, fuel, medicine and other supplies.
