The United Nations Children's Fund (UNICEF) says malnutrition among children is spreading fast and reaching devastating and unprecedented levels in the Gaza Strip due to the wide-reaching impacts of Israel’s war and its ongoing blocking of aid deliveries. At least 31 people - including 27 children - have died of hunger and dehydration in recent weeks. Since October 7, more than 13,450 children have been killed in the tiny territory, according to Gaza officials.
