Many water facilities have been damaged or destroyed by Israel’s war in Gaza, according to the UN and others, compounding the civilian population’s suffering, risking the spread of disease and leading human rights experts to accuse Israel of using water supply as a weapon.
Since you ignored the question I can only assume the answer is yes.
There are humanitarian zones for the civilians with more than enough water.
The situation there is shitty, but to the blame of all the suffering on Israel alone is just plain wrong.
