A report from the UN Children's Fund, or UNICEF, says water-production capacity in the Gaza Strip has plummeted to 5 percent of the pre-conflict level.

The report, compiled in November, says the Strip's water supply relies on three main sources. More than 300 boreholes across Gaza provide some 80 percent of its water needs. Around 13 percent comes from Israel, and seawater desalination plants provide the remaining 7 percent.

The report blames the decline in the water-production capacity on fuel shortages and infrastructure damage from Israeli attacks in Gaza, among other causes.

Philippe Lazzarini, the commissioner-general of the UN Relief and Works Agency for Palestine Refugees, early last week accused Israeli military operations of disabling Gaza's largest seawater desalination facility, limiting access to water.

The United Nations Office for the Coordination of Humanitarian Affairs, or OCHA, says that according to information it received on Friday, almost all of the wells, which are used by many Gazans, had stopped working due to lack of fuel.

The UNICEF report says Gaza's residents are relying on only 3 liters of water per person a day for drinking, cooking and hygiene.

It says this forces many of them to resort to non-potable water sources, and medical teams have noted a rise in cases of acute respiratory disorders and diarrhea among young children as a result.

Meanwhile, limits on deliveries of water, fuel and other aid supplies from Egypt into Gaza are still in place. OCHA says only 100 trucks carrying humanitarian supplies entered Gaza on Sunday. This is well below the daily average before October 7, which stood at 500 truckloads.

OCHA also says fuel supplies for water production, sewage treatment and other related operations are at 35 percent of the required amount.

The United Nations is urging Israel to open its Kerem Shalom crossing into Gaza as early as possible to supplement the aid coming through the Rafah crossing from Egypt. The question now is whether relevant parties can agree on the opening of Kerem Shalom to improve the humanitarian situation in the Palestinian enclave.
