GAZA/JERUSALEM: U.N. aid deliveries to Gaza were suspended again on Friday due to shortages of fuel and a communications shutdown, deepening the misery of thousands of hungry and homeless Palestinians as Israeli troops battled Hamas in the enclave.

The United Nations' World Food Programme (WFP) said civilians faced the "immediate possibility of starvation" due to the lack of food supplies.

Palestinian news agency WAFA said a number of Palestinians were killed and others injured in an Israeli strike that hit a group of displaced people near the Rafah border crossing between the Gaza Strip and Egypt - the transit point for aid.

Al Jazeera TV cited sources as saying that nine people were killed in the strike. There was no immediate comment from Israel on the reported strike and Reuters could not verify it.

In other developments, Israel said its troops had found a tunnel shaft used by Hamas at Al Shifa hospital in the north of the Gaza Strip.

The hospital, packed with patients and displaced people and struggling to keep operating, has been a major focus of global concern this week. Israel says Hamas has stored weapons and ammunition and is holding hostages in a network of tunnels under hospitals like Shifa, using patients and people taking shelter there as human shields. Hamas denies this.

With the war about to enter its seventh week, there is no sign of any let-up despite international calls for a ceasefire or at least for humanitarian pauses.

The conflict was triggered by a cross-border raid by Hamas on Oct. 7 that killed about 1,200 Israelis, mostly civilians, in the deadliest day in the state's 75-year-history.

More than 11,500 Palestinians, at least 4,700 of them children, have now been killed in Israel's retaliatory military assault on Hamas-ruled Gaza, according to the Palestinian Health Ministry - a toll that far surpasses previous bouts of conflict in recent years.

Israel has vowed to wipe out the group. Whole neighbourhoods of Gaza have been flattened in air and artillery strikes, hundreds of thousands of people have been forced to flee their homes, and the humanitarian situation is catastrophic, aid agencies say.

TRUCKS SUSPENDED

The United Nations said there would be no cross-border aid operation on Friday due to fuel shortages and a communication shutdown. For a second consecutive day on Thursday no aid trucks arrived in Gaza due to lack of fuel for distributing relief.

WFP Executive Director Cindy McCain said nearly the entire population was in desperate need of food assistance.

"Supplies of food and water are practically non-existent in Gaza and only a fraction of what is needed is arriving through the borders," she said in a statement.

"With winter fast approaching, unsafe and overcrowded shelters, and the lack of clean water, civilians are facing the immediate possibility of starvation," McCain said.

The Israeli military's chief of staff said Israel was close to destroying Hamas' military system in the northern Gaza Strip and there were signs the army was taking its campaign to other parts of the coastal enclave of 2.3 million people.

Israel accused Hamas of preventing people from heading to the south of the Gaza Strip, which the group denied.

The army released a video it said showed a tunnel entrance in an outdoor area of Al Shifa, Gaza's biggest hospital.

The video, which Reuters could not immediately verify, showed a deep hole in the ground, littered with and surrounded by concrete and wood rubble and sand. It appeared the area had been excavated. A bulldozer appeared in the background.

The army said its troops also found a vehicle in the hospital containing a large number of weapons.

Reuters journalists have been unable to reach anyone inside Shifa hospital for more than 24 hours.

Hamas said on Thursday that claims by the United States that the group uses Shifa for military purposes was "a repetition of a blatantly false narrative, demonstrated by the weak and ridiculous performances of the occupation army spokesman".

Israeli officials had said Hamas held some of the 240 hostages taken by gunmen on Oct. 7 in the hospital complex.

On Friday, the Israeli military said soldiers retrieved the body of a female soldier who had been held captive, in a building near Shifa.

The military had confirmed her death on Tuesday after Hamas issued a video of her alive followed by images of what it said was her body after she was killed in an Israeli strike.

On Thursday, troops recovered the body of another woman hostage, also in a building near Shifa.

In the Israeli-occupied West Bank, Hamas's Al-Quds Brigades said they had engaged Israeli forces for several hours in the city of Jenin overnight into Friday, unleashing a "torrent of fire" and laying ambushes with explosives.

Israel's military said that war planes struck in Jenin who had opened fire on Israeli soldiers. It said at least five were killed.

At least 178 Palestinians have been killed in the West Bank since the Oct. 7 Hamas attack on Israel. The violence there has underscored fears that the territory, seized by Israel in the 1967 Middle East War, could spiral out of control in tandem with the conflict in Gaza.
