Also withholding diesel fuel that could run the pumps already in the area, along with makeshift housing that has been sent for them.

As Gaza floods overwhelm displacement sites, municipal teams in Al Maghazi refugee camp face a difficult trade-off: pumping rainwater out of shelters means taking fuel away from the wells that supply residents with water.

“The diesel we use for these pumps comes from the allocation for the wells that are supposed to pump water,” municipal engineer Imad Abdel Jawad tells WIRED Middle East.

There is no separate fuel allocation for removing floodwater, he says. Diverting diesel affects the operation of the wells, at a time when their supply is already insufficient.

While the "ceasefire" announced over a year ago stipulated the entry of caravans as a more durable alternative to tents, Israeli authorities have repeatedly blocked their entry into Gaza, leaving hundreds of thousands of children exposed to another winter of hardship, said Save the Children.

I do worry that after years of headlines like this one, people might scroll past and miss how significant this situation is.

Some facts from the second link

• Around 70,000 tents flooded in a single day during Gaza's first winter storm.
• More than 560,000 children are estimated to be living in critical or catastrophic shelter conditions.
