The situation in Rafah is “overwhelmingly catastrophic” as an estimated 1.5 million people remain crammed in a patch of land that was home to 250,000 before the war, according to Save the Children.

“Overcrowding is the first thing that you can notice, there are people everywhere,” Soraya Ali, global media manager at Save the Children, told Al Jazeera from Rafah.

“There are children with rashes as communicable diseases are spreading. We have seen children with one or both limbs missing and many are malnourished as nowhere near enough food is getting through [the Rafah crossing] right now.

“We’ve seen aid coming in at an alarmingly slow rate,” Ali said, adding that trucks were being turned away.
