The vast majority of Gaza’s population now lives in tents, leaving them vulnerable to disease and food insecurity as winter approaches, according to the World Health Organization.

The Director-General of the World Health Organization, Tedros Adhanom Ghebreyesus, said Saturday that almost all of those displaced in Gaza a year ago by Israel’s war against Hamas were sheltered in public buildings or family members.

“Now, 90% live in tents,” Tedros said in a post by Masa X (formerly Twitter), saying that exposed living conditions make people “vulnerable to respiratory and other diseases,” noting that cold weather and rains are expected to exacerbate malnutrition and food insecurity in the Strip.

The Financial Times confirmed that the flow of aid to Gaza reached its lowest level since the beginning of the war, after the Israeli army took operational control of the Palestinian side of the Rafah crossing last May.
