World aid groups have criticized Israel for the growing humanitarian crisis in Gaza. Israel has denied the accusations.

Operations in three parts of the enclave were temporarily halted on Sunday to allow more aid to enter the territory, the Israeli military said. It was unclear if the decision would relieve the hunger crisis in Gaza.

For months, the U.N. and experts have warned that Palestinians in Gaza are at risk of famine, with reports of increasing numbers of people dying from causes related to malnutrition.
