Israel intensified its militar forcing tens of thousands of Palestinians to# flee and making it more difficult to deliver aid.

AMNA NAWAZ: The United Nations says nearly 1.9# million people, or over 80 percent of Gaza's## population, have been displaced by the war,# many several times over.

They're now crowded## into small areas in South and Central Gaza, with# the humanitarian situation worsening by the day.

Southern Gaza is now the center of the war.# And, once again, civilians bear the brunt,## caught between Hamas hiding among them and# Israel's bombardment.

In Khan Yunis overnight,## Amal Mehdi and her two children were# jolted awake by an Israeli airstrike.## Sifting through the wreckage, she# says they're lucky to be alive.

AMAL MAHDI, Displaced Gazan (through translator):# We were peacefully sleeping, not bothering asleep, and I have young children,# minding our own business.

All of a the bombardment hit us.

It was a miracle# that we were pulled from under the rubble.

Israel says its troops have fully breached# Khan Yunis in what they call a third phase## of ground operations, surrounding# the house of Gaza's Hamas leader,## Yahya Sinwar.

And the Israel Defense# Forces released this rare image of 11## Hamas military commanders, five of# whom the IDF says have been killed.

But fighting continues in the north.# Officials today claimed they discovered## the largest weapons cache yet near# a school in Gaza City.

Palestinians,## meanwhile, are being pushed# into rapidly shrinking spaces.

Mohammed Hamo fled his home in the north.

MOHAMMED HAMO, Displaced Gazan (through# translator): They told us to go to t because it is safe.

Nothing AM NA NAWAZ: In the overcrowded Nasser Hospital,# 11-year-old Saba Magnum with an injured arm## frantically searches for her father.

Her younger# siblings collapse into tears when he's found.

They're told that he's just injured his leg,## but they cling to their father, injured# in an airs SABA MAGNUM, 11-Year-Old Airstrike Survivor# (through translator): We were at the school.## They hit us twice.

I AMNA NAWAZ: Five-year-old Amir was there.

AMIR MAGNUM, 5-year-Old Airstrike Survivor# (through translator): I went in and went to play with my we ran.

Father -- a big rock fell on my father,# hit him here.

And a big rock fell on me here.

AMNA NAWAZ: Hospitals elsewhere have become# funeral grounds.

Mourners gathered outside this## facility in Deir al Balah, reciting prayers# beside dozens of bodies lining the street.

According to Doctors Without Borders, hospitals# are running critically low on fuel and medical## supplies with some 200 wounded brought in every# day.

At the nearby U.N. distribution center,## crowds desperate for food waited# hours for a small portion of flour.

Um Hussein says she's risking her# life to provide for her family.

UM HUSSEIN, Displaced Gazan (through# translator): The way they are gathering here,## if there was bombing right now, di stribution centers in every area.

I didn't# get anything.

Where am I supposed to go?

VOLKER TURK, United Nations High# Commissioner for Human Rights: There is a## he AMNA NAWAZ: In Geneva today, the# U.N.'s human rights chief, de scribed the situation in Gaza as apocalyptic.

VOLKER TURK: Some 1.9 million out of the 2.2# million Palestinians hav are being pushed into ever-diminishing and# extremely overcrowded places in Southern## Gaza in unsanitary and unhealthy# conditions.

And humanitarian aid## is again virtually cut off as fears of# widespread disease and hunger spread.

AMNA NAWAZ: Meanwhile, the future of postwar# Gaza remains uncertain.

After a report that## Palestinian Authority President Mahmoud Abbas# said he would be willing to assume governance,## Israeli Prime Minister Benjamin Netanyahu# posted -- quote -- "Those who educate their## children for terrorism, finance# terrorism and support terrorist## families will not be able to rule# Gaza after eliminating Hamas."

Whatever happens next, Gazans like May Selim are# determined to stay there.

Sheltering in a tent## city less than a mile from the Egyptian border,# she says she'd rather die than move any further.

MAY SELIM, Displaced Gazan (through translator):# For us, this is the last stop.

After that,## if they want to forcibly displace us,# we will not leav right here.

But we will not leave our land# and our entire lives.

We will not do that.
