As most water well stations are shut down due to a lack of electricity and fuel, Palestinians living close to the beach use the water for showers and for cleaning clothes.

Israel has launched relentless air and ground attacks on the Gaza Strip since a cross-border attack by the Palestinian resistance group, Hamas, on Oct. 7.
Since then, more than 12,000 Palestinians have been killed, including over 8,300 women and children, and more than 30,000 others have been injured, according to the latest figures.
