New ground and air offensive comes after dozens of Palestinians seeking aid were killed in one of the deadliest incidents in months.

ABC News captured harrowing scenes of malnourished children in a Gaza hospital as over 100 aid groups warn of “mass starvation” across the Strip.

Israel launched an air and ground offensive into the only Gaza city that had not seen major military operations since the war began.

Context: Deir al-Balah had been an informal refuge for Palestinians escaping other parts of Gaza, and huge tent camps have sprung up in the city. The city also hosts warehouses for the U.N. as well as guesthouses for U.N. staff.

Israel launched a ground offensive in central Gaza for the first time, ordering out many thousands of Gazans who had sought the relative safety of the area.
