The UN 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, Al Jazeera reports.

Rights groups have accused Israel of committing crimes against humanity by blocking aid delivery into the enclave. Israel has also been accused of reneging on the Gaza ceasefire that ended its brutal 15 months of fighting in the enclave.

Israel allowed humanitarian aid during the first six weeks of the ceasefire. But the World Food Programme said on Wednesday that its stocks are low because it prioritised delivering food to the population.

The UN agency also warned that its fuel stocks would only last for a few weeks.
