The United Nations warned Friday that "many more will die" as a result of Israeli Occupation's ongoing siege of Gaza, which has also caused sewage to flow on the streets of the Palestinian territory.

Israel Occupation laid a total siege on Gaza following the October 7 operation by Hamas, cutting off food, fuel, water and power supplies to the territory.

"As we speak people in Gaza are dying, they are not only dying from bombs and strikes, soon many more will die from the consequences of (the) siege imposed on the Gaza Strip," said Philippe Lazzarini, commissioner general for the UN agency for Palestinian refugees (UNRWA).

"Basic services are crumbling, medicine is running out, food and water are running out, the streets of Gaza have started overflowing with sewage."
Lazzarini called for more aid to be immediately allowed into Gaza during a press conference in Jerusalem.

"The current system in place is geared to fail. What is needed is meaningful and uninterrupted aid flow. And to succeed, we need a humanitarian ceasefire to ensure this aid reaches those in need," Lazzarini said.

Limited convoys of aid have entered through Gaza's Rafah crossing with Egypt, but the UNRWA chief noted that they have not included fuel, which is vital to keep critical services running.

"What needs more support? Bakeries, water stations, life support machines in a hospital -- all this needs fuel to function," he said.

"As far as UNRWA is concerned, we have fuel for today," said Lazzarini.

The agency has "drastically limited" its fuel consumption, he said, and normally needs 160,000 liters per day for its operations.

Israeli Occupation has said it will not allow fuel to enter Gaza, arguing it could reach Hamas.

Lazzarini dismissed the claim that aid convoys could be diverted.

"Let me be clear: we have solid monitoring mechanisms... UNRWA does not and will not divert any humanitarian aid into the wrong hands," he said.

Alongside the siege, Israeli Occupation has bombarded Gaza with air and artillery strikes since October 7.

Lazzarini said 57 UNRWA staff have been killed in Gaza during the war, describing them as "wonderful people who have just dedicated their lives to their communities".
