AMNA NAWAZ: Welcome to the "NewsHour."

United Nations officials today said that starvation was an increasing possibility in Gaza, as they were forced to stop food and aid deliveries due to a lack of fuel.

The communications blackout continues with no generator power.

Israel has now said it will allow two tankers a day to enter for U.N. operations.

That's about half of what they need.

And that's just for the most vital operations.

Palestinian officials said today that the death toll has surpassed 12,000.

Leila Molana-Allen reports.

LEILA MOLANA-ALLEN: In Central Gaza's Nuseirat camp, residents search the rubble for the living and the dead, their bare hands their only tools, after an Israeli airstrike reportedly killed at least 40 people.

In Southern Gaza's Khan Yunis, once a refuge for the Abu Zanad family, now smashed concrete.

Hani Abu Zanad has lost hope, HANI ABU ZANAD, Khan Yunis Resident (through translator): Every second of every minute, there's a massacre.

What humanitarian cease-fires?

They say the south is safe.

What safety?

LEILA MOLANA-ALLEN: Just yesterday, Israeli forces dropped leaflets warning Khan Yunis residents to move elsewhere.

Many here were forced to leave their homes in North Gaza.

They came here because the IDF told them the south is safe.

Alaa Abu Hasira lost 11 members of her family, including both her children.

ALAA ABU HASIRA, Displaced From Gaza City (through translator): We were in Gaza City and as a result of the conflict, we moved to Khan Yunis.

All my sisters died and my son and daughter also.

I wish I had taken her in my arms.

And my twin sister also died.

LEILA MOLANA-ALLEN: South Gaza's Nasser Hospital is overwhelmed.

Streams of wounded are brought here, including children, two sharing a single bed, as doctors pump oxygen manually, babies injured by burning shrapnel and falling buildings.

The grief is crippling.

In the north, IDF troops occupied parts of Gaza cities Al Shifa Hospital for a third day.

MAN: RPGs.

LEILA MOLANA-ALLEN: Yesterday, the IDF released this video of weapons they say were found on the hospital grounds, but, so far, they have haven't shown evidence of their claim that Hamas runs a command center underneath Al Shifa.

Dr. Ahmed El Mokhallalati is a senior plastic surgeon inside Al Shifa.

DR. AHMED EL MOKHALLALATI, Al Shifa Hospital: They have found nothing.

They have found here no single resistance, no single gunshot against them within the hospital area.

It's totally aggressive attack on the hospital, which is totally full of civilian patients.

LEILA MOLANA-ALLEN: The hospital has been under siege for over a week.

He described the terrifying conditions inside.

DR. AHMED EL MOKHALLALATI: The snipers have almost shot everyone who tried to move within that building.

We can move only in the middle of the day.

If I have any patients who need help, I can't go there.

There is no communication at all.

It's totally scary.

We can't even checking and searching the east part of the hospital.

And no one is firing against them.

They keep bombing all the areas around.

They keep firing all over the areas.

LEILA MOLANA-ALLEN: Palestinian health officials say more than 600 patients, including 36 premature babies, remain trapped inside the hospital.

Six babies have died.

And thousands of displaced civilians are still taking shelter in the hospital complex.

In Israel, 65-year-old Yehudit Weiss' family is in mourning.

Weiss was one of around 240 hostages kidnapped by Hamas terrorists on October 7.

Yesterday, the IDF recovered her body from near Al Shifa.

Her brother, Avishay Kaminer, feels betrayed.

AVISHAY KAMINER, Brother of Victim: Such tragedies could have been avoided if we only had someone who really cared about all those kidnapped.

LEILA MOLANA-ALLEN: In the occupied West Bank's Jenin refugee camp, hundreds gathered for the funeral of three men killed last night in Israeli drone strikes.

The IDF said at least five militants were killed in the fighting.

More than 200 Palestinians have been killed by the IDF since October 7.

Israeli forces also raided hospitals in Jenin.

Eyewitness video shows medical staff coming out of a hospital with their hands up.

Hospitals, protected by international law, are increasingly under attack in this war.

Palestinians, homeless and helpless, say they have no safe harbors left.
