Save the Children has condemned the resumption of the onslaught, saying the international community “cannot turn a blind eye as children in Gaza once again are at risk of being killed, maimed, displaced, starved, and left even more vulnerable to disease and the elements”, Al Jazeera reports.

Rachael Cummings, Save the Children’s humanitarian director based in central Gaza’s Deir el-Balah, said the collapse of the ceasefire was “nothing short of a death sentence for Gaza’s children.”

The denial of aid coinciding with the start of the holy month of Ramadan also amounts to “a grave violation against children”, Cummings said.

“We demand an immediate and definitive ceasefire and restrictions on humanitarian aid to be immediately lifted,” she added. “Anything less is a catastrophic failure to uphold international humanitarian law and protect the most vulnerable.”

Dozens of children were among the more than 400 victims killed by Israeli air strikes in recent hours.
