At least 66 children have died of malnutrition in Gaza over the course of Israel’s offensive in the enclave, authorities in Gaza said, Al Jazeera reports.

The media office said Israel’s deadly blockade constitutes a “war crime” and reveals its “deliberate use of starvation as a weapon to exterminate civilians”.

The office denounced what it called “this ongoing crime against childhood in the Gaza Strip” as well as “the shameful international silence regarding the suffering of children who are left to fall prey to hunger, disease, and slow death”.

It also said it holds Israel, as well as its allies, including the United States, the United Kingdom, France and Germany, responsible for “this catastrophe”, and urged the United Nations to intervene and open the crossings into Gaza immediately.
