Thousands of children have been admitted for treatment for acute malnutrition in Gaza since an October ceasefire that was supposed to enable a major increase in humanitarian aid, the U.N. children‘s agency said on Tuesday.

UNICEF, the biggest provider of malnutrition treatment in Gaza, said that 9,300 children were treated for severe acute malnutrition in October, when the first phase of an agreement to end the two-year Israel-Hamas war came into effect.
