One in five people in the Gaza Strip are facing starvation as the entire territory edges closer to famine, a new United Nations-backed report warns, after nearly three months of Israel’s blockade of critically needed humanitarian aid.

The risk of famine and mass starvation is rising in Gaza, the World Health Organization warns. Palestinian health officials say dozens of children have died of malnutrition since March, the month Israel blocked all aid shipments.
