Aid agencies warned for months that Israel’s harsh limits on food aid would bring acute malnutrition and widespread suffering to Gaza’s 2.1 million people.

World Health Organization chief Tedros Adhanom Ghebreyesus spoke following an appeal by more than 100 aid agencies warning of hunger in Gaza while tons of food, clean water and medical supplies sit untouched just outside the territory.

More than 100 organizations, including Save the Children and Doctors Without Borders, added to growing calls for aid restrictions to be eased and the war to end.
