In a statement, the Hamas-run government media office said that about "70,000 tents sheltering tens of thousands of displaced people were flooded on the first day" of rains.

It also noted the "collapse of dozens of cracked walls and roofs, which caused injuries", some critical, in various areas of the tiny territory.

Since early Saturday, hundreds of displaced families have been seen fleeing camps in parts of Gaza City and in the central and northern areas of the Strip after they were inundated by rainwater.
