The United Nations Security ca lls for -- quote -- "urgent and extended"# humanitarian pauses in the fighting between## Israel and Hamas in Gaza.

The U.S.,# United Kingdom, and Russia abstained.

Meanwhile in Gaza, the focus is# on the largest hospital there.

GEOFF BENNETT: Israeli forces entered the Al Shifa# Hospital and the compound that da wn this morning, with hundreds of patients# and doctors still there, but in dire shape.

Israel and the U.S. say the hospital# is used by Hamas as a command center,## a charge the staff and Hamas both deny.

John Yang has the story.

JOHN YANG: Inside Gaza city's biggest# hospital, clouds of dust and toxic smoke## from Israeli shelling, as doctors# and patients struggle to breathe.

The Shifa Hospital is no longer# safe.

In the intensive care unit,## a doctor narrates the aftermath in this video# released by the Hamas-run Gaza Ministry of## Health.

Even the youngest are deprived# of life support.

Rows of critical care## patients were moved to the corridor# away from life-supporting machines.

The doctor is pumping oxygen manually,# he said, as this little girl struggles## to breathe.

Israeli forces entered# the Shifa Hospital compound at dawn## in what the IDF have called a precise and# targeted operation in one specific area.

In a statement, the Palestinian Mission to# the United States called it a war crime and## said Israeli soldiers terrorized civilians,# ransacked rooms, destroyed equipment, and## beat medical staff, whom they interrogated at gun# point.

Israel says Shifa is not just a hospital## but also a Hamas command-and-control center,# something Hamas and hospital officials deny.

LT. COL. JONATHAN CONRICUS, International# Spokesperson, Israel Defense Forces: We## are inside JOHN YANG: After searching for more than# 12 hours of search, the IDF released thi video as evidence showing a cache# of weapons they said they found.

LT. COL. JONATHAN CONRICUS: If you# follow me behind the MRI machine,## I will show you what our troops# exposed just minutes ago.

There is an AK-47.

There are cartridges,# ammo.

There are grenades in here,## of course, uniforms, and all of# this was hidden very conveniently,## secretly, behind the MRI machine.

A# laptop, we found it in the MRI room.

JOHN YANG: The IDF also claimed their search# turned up technological assets belonging to Hamas.

Just hours before the raid, the United States said## it has intelligence that Hamas# uses hospitals, includ as military strongholds.

But officials also# said the United States did not license the ra Israeli Prime Minister Benjamin Netanyahu# said no place in Gaza is off-limits.

BENJAMIN NETANYAHU, Israeli Prime Minister# (through translator): They said that we would not## reach the outskirts entered.

And in this spirit we say a simple thing.# There is no place in Gaza that we will not reach.

JOHN YANG: Palestinian health# officials say 650 patients and## thousands of displaced civilians remain# trapped inside the hospital ground including medical staff who chose# to stay behind to care for them.

Dr. Shadi Issam Radi remained with his two## children.

His wife was killed three# weeks ago in an Isra DR. SHADI ISSAM RADI, Al Shifa Hospital# (through translator): I have worked in# the intensive care department for seven years.# My wife was killed while I was working.

I was obliged to bring the children with me and I# am still working.

Thank God for everything.

JOHN YANG: Elsewhere in Gaza, no end to death# and destruction.

In Khan Yunis in the south,## this was a shelter for a family who had# fled from the north.

But for some of them,## it became a tomb, at least one woman and two# children reportedly killed.

This baby survived.

At the only open crossing# along the Gaza-Egypt border,## a truck carrying the first load of# fuel entered the strip.

Expert said## the roughly 6,000 gallons will do little to# alleviate the shortages.

And Israel said it## will only supply it to U.N. aid efforts, not# hospitals, for their now-silent generators.

MARTIN GRIFFITHS, U.N. Undersecretary-General# for Humanitarian Affairs and Emergency Relief## JOHN YANG: In Geneva today, the U.N.'s# emergency relief coordinator, Martin Griffiths,## urged Israel to allow a continuous flow of aid# and to open more crossings along the border.

MARTIN GRIFFITHS: We have the trucks.

We# need the fuel and we need the money to## fund the delivery.

And then we can do the# job that we are there to do.

Silence those## guns long enough to give the people# of Gaza a breather from the terrible,## terrible things that have been# put on them these last few weeks.

JOHN YANG: Aid desperately needed# at medical facilities across Gaza,## like Al-Aqsa.

Today, doctors scrambled# to treat the injured caught in the,## crossfire of a war where hospitals# have become battlegrounds.
