GEOFF BENNETT: Welcome to the "News Hour."

The U.S.

defense secretary said today that# the war with Iran has only just begun, and## the war expanded once again.

Iran for the first# time fired a drone into NATO territory, and the## U.S.

used a torpedo fired by a submarine to sink# a warship for the first time since World War II.

The U.S.

says it has struck more than# 2,000 targets.

Iran's Health Ministry## says more than 920 people there have been killed.

Our Nick Schifrin starts our coverage.

NICK SCHIFRIN: Today, Tehran woke to terrifying# booms that engulfed the night sky and flames,## by day, the capital's Revolutionary# Square battered, many buildings broken,## and structures shattered as rescue# workers prayed for the dead.

Monireh Tehrani cannot believe what she's seen.

MONIREH TEHRANI, Tehran Resident (through# translator): I hope this ends sooner,## and so many people won't be killed anymore.

PETE HEGSETH, U.S.

Defense Secretary:# We are punching them while they're down,## which is exactly how it should be.

NICK SCHIFRIN: In Washington, Pentagon leaders# said U.S.

strikes had so far focused on Iran's## ballistic missile infrastructure and drones in# Iran's west and northwest.

And U.S.

strikes will## soon spread deeper into Iran now that the# U.S.

has more control over Iran's skies.

GEN.

DAN CAINE, Chairman, Joint Chiefs of# Staff: We will now begin to expand inland,## striking progressively deeper# into Iranian territory.

NICK SCHIFRIN: And the U.S.

expanded the# war zone today with an event not seen in## more than 80 years.

A submarine's torpedo# sunk the Iranian warship IRIS Dena off the## coast of Sri Lanka.

The ship was returning home# from an exercise hosted by India.

Sri Lankan## authorities rescued 32 sailors and recovered# nearly 100 bodies, with dozens still missing.

In total, the U.S.

says it has sunk 20 Iranian# ships.

And, today, Israel said it continues## to attack Iran's military, including internal# security services and leadership.

In Southern## Iran, the war has trapped civilians.

At this# hospital, the Iranian Red Crescent showed a## neonatal ward whose ceiling was damaged.# Medical staff evacuated premature babies.

Outside Tehran University, Iranians remembered# assassinated Supreme Leader Ali Khamenei and## the bloodstained belongings of# more than 100 killed schoolgirls,## an attack that the U.S.

says# it is still investigating.

MOHAMMADREZA JAMA'ATI, Tehran Resident# (through translator): The system does## not depend on one person.

If one lead.. NICK SCHIFRIN: And Iran's resistance has included# firing more than 2,500 missiles and drones,## although the U.S.

today said these missile# launches have recently reduced by 23 percent.

Today, for the first time, one targeted# NATO.

Turkey said air defense shot down an## Iranian missile in the country's south.

Many of# Iran's targets are Arab Gulf energy facilities,## including this Emirati oil industry zone,# today covered in flames and thick smoke.

Iran's president wrote directly# to Arab governments today,## saying -- quote -- "The American# Zionist military attack has left## us no choice but to defend ourselves.# We respect your sovereignty and still## believe that the region's peace must be# ensured by the countries of the region."

REP.

MIKE JOHNSON (R-LA):# We're not at war right now.

NICK SCHIFRIN: On Capitol Hill, Iran has sparked# a divide along party and over nomenclature.

REP.

MIKE JOHNSON: We have to ensure# that they can't fire all those barrage## of missiles at our people, our troops, our# assets, our citizens in the region and our## installations.

We're taking that out.# We had to.

It's a defensive operation.

NICK SCHIFRIN: This afternoon,# the Senate rejected a bill that## would have demanded congressional# approval before further attacks.## But some Republicans are voicing# concerns if those attacks continue.

REP.

NANCY MACE (R-SC): I will# be a no for now.

But if this## thing goes beyond a few weeks, I'm# going to have a lot more concerns.

NICK SCHIFRIN: The war's first American# fatalities, reservists assigned to the## 103rd Sustainment Command out of Des Moines,# Iowa.

They worked behind the lines in logistics,## killed when their reportedly unreinforced# building in Kuwait was hit by an Iranian drone,## 39-year-old Sergeant 1st Class Nicole# Amor, 25-year-old Captain Cody Khork,## 42-year-old Sergeant 1st Class Noah Tietjens, and# Sergeant Declan Coady, whose family says he was## considering extending his deployment to Kuwait# because he found the work hard but rewarding.

Andrew is Declan's father.

ANDREW COADY, Father of Declan Coady: One thing# he did say is that: "I hav.. but I have had jobs in the civilian world.# And I have been over here for six months,## and I work 12-plus-hour days.

I work six to# seven days a week."

And he goes: "I love it."

KEIRA COADY, Sister of Declan Coady: This was the## morning before we .. NICK SCHIFRIN: Keira is Declan's older sister.

KEIRA COADY: He's 20.

He was going to be 21 in# two months.

I just really wish I got to tell## him I love him one more time, because he was just# so amazing.

I can't help but think just he was my## little brother, and he was probably really scared,# even if he didn't want people to know.

So I just## wish he could have known one more time that we# all loved him, because he was so amazing and kind.

NICK SCHIFRIN: Keira said Andrew was the# best little brother she could have had,## just one family, Geoff, of the six Americans# killed so far in this war since Saturday.

GEOFF BENNETT: Our hearts certainly# go out to all of those families, Nick.

We have spoken on this broadcast# over the last couple of days about## the effort to evacuate Americans from# the region.

How is that progressing?

NICK SCHIFRIN: The State Department# said today that 17,500 Americans had## returned from the Middle East, about 6,500# of them thanks to State Department efforts.

U.S.

officials say that most have left on# commercial flights.

Some of them have left on## charter flights and also U.S.-arranged ground# transport to cities where the airports aren't## closed.

As we have been talking about, many cities# across the region, those airports are closed.

And, this morning, the chairman# of the Joint Chiefs also said the## military had opened up seats on# transport and other planes when## those seats had become available.

But# we have spoken to former officials,## a retired three-star who was in the region when# the war started.

I spoke to a former ambassador.

Both of them criticized the Trump# administration for not handling this sooner,## not evacuating people perhaps three, four,# five days before the war started.

President## Trump was asked that question just yesterday.# He said that the war started too quickly and## there was just simply no time to# be able to evacuate people early.

There's also been criticism that the message## played on the phone number for American# citizens to call yesterday, said:## "Please do not rely on the U.S.

government for# assisted departure."

Today, the State Department## updated that message so people can actually# talk to actual human beings to help them out.

And, at this point, this is the guidance that# the State Department is giving.

You can see## this on this graphic right here.

U.S.

citizens# need to register with the State Department.## They have to follow the State Department# on -- via WhatsApp and call this number,## 202-501-4444.

That's the number at the bottom.

Geoff, that's because you have# to make that call because,## until people actually register or tell# the State Department where they are,## the State Department suddenly doesn't know# how many people need to get out and how.

GEOFF BENNETT: Nick Schifrin, thanks,# as always, for your reporting.

NICK SCHIFRIN: Thank you.
