GEOFF BENNETT: Welcome to the "News Hour."

Tonight, the war with Iran is on the verge# of escalation, with President .. threatening to target Iran's power grid and# Tehran vowing even more forceful strikes on## Israel and U.S.

Gulf allies if there# is no cease-fire by tomorrow night.

AMNA NAWAZ: The president simultaneously# expressed confidence in a diplomatic outcome,## but there's no public sign# of progress.

Also today,## the U.S.

celebrated the successful mission that# rescued the American aviators shot down on Friday.

Nick Schifrin begins our report on a# busy day in Iran and at the White House.

NICK SCHIFRIN: Today in Tehran, another# dawn lit up by airstrikes on an airport## and an apartment building cut in half in an# attack that state media reported killed six,## as President Trump threatened escalation.

DONALD TRUMP, President of the United# States: We have a plan because of the## power of our military where every bridge in# Iran will be decimated by 12:00 tomorrow night,## where every power plant in Iran# will be out of business, burning,## exploding and never to be used again,# I mean, complete demolition by 12:00.

NICK SCHIFRIN: Yesterday,# he used coarser language,## threatening -- quote -- "Tuesday will be power# plant day and bridge day all wrapped up in## one in Iran.

There will be nothing like# it.

Open the (EXPLETIVE DELETED) strait,## you crazy bastards, or you will be living# in hell.

Just watch.

Praise be to Allah."

DONALD TRUMP: They have until tomorrow.# Now, we will see what happens.

I can tell## you they're negotiating, we think, in# good faith.

We're going to find out.

NICK SCHIFRIN: This weekend, mediators from# Pakistan, Turkey and Egypt reportedly offered## a 45 day cease-fire, during which Iran would# open the Strait of Hormuz and the U.S.

and Iran## would negotiate the end of the war.

Iranian# state media reported that Iran rejected that,## demanding the end of the war, sanctions relief,# reparations and financial control over the Strait## of Hormuz, through which 20 percent of the# world's oil and natural gas usually flows.

DONALD TRUMP: We have to have a deal# that's acceptable to me.

And part of## that deal is going to be, we want free# traffic of oil and everything else.

QUESTION: Mr.

President are you# allowed to -- or are you willing## to end this conflict with Iran charging# tolls for passage through the strait?

DONALD TRUMP: Us charging tolls?

QUESTION: Iran.

DONALD TRUMP: What about us charging tolls?

QUESTION: Is that something you're considering?

DONALD TRUMP: I'd rather do that# than let them have them.

Right.## Why shouldn't we?

We're the winner.

We# won, OK?

They are militarily defeated.

NICK SCHIFRIN: But Iran maintains its# ability to threaten U.S.

allies.

Today,## Israeli families cowered in# fear during an Iranian attack.

Last night, Iran launched a barrage of# cluster munitions that break up into that## break up into small bombs that# fly miles apart.

And, today,## rescue workers in Haifa dug out the bodies of# four victims; 23 Israeli civilians have now## been killed since the start of the war.# Today, Iran vowed its own escalation.

LT.

COL.

EBRAHIM ZOLFAGHARI, Iranian Military# Spokesperson (through translator): If attacks## on civilian targets are repe.. and retaliatory operations will be# carried out much more forcefully.

NICK SCHIFRIN: Israel has already been striking# civilian targets that it says are also used by## the Iranian military.

Today, it was a# petrochemical plant and Tehran's Sharif## University of Technology that professors# said had no connection to the military.

This was not only once a place of learning, but# also protest.

Four years ago, the university's## students demonstrated against the regime# for killing activist Mahsa Amini.

Back then,## they fled from the very same security forces# that Israel has said hopes will be overthrown.

DONALD TRUMP: We're here today to celebrate# the success of one of the largest,## most complex, most harrowing combat searches.

NICK SCHIFRIN: The White House today also# celebrated this weekend's historic rescue,## what the military said included more than 150# aircraft and hundreds of special operations## forces inside Iran to save the pilot# and weapons service officer of an F-15## after it was shot down on Friday by a# shoulder-fired surface-to-air missile.

Iranian police posted the Americans'# documents.

The pilot was rescued within hours,## but the weapons service officer# was missing, dozens of miles away.

DONALD TRUMP: He scaled cliff# faces, bleeding rather profusely,## treated his own wounds, and contacted# American forces to transmit his location.

NICK SCHIFRIN: He survived more than 50 hours,# during which time the Iranian regime offered a## bounty to find him.

U.S.

helicopters flew# so low, locals targeted them with rifles.## The mission was risky and needed multiple# contingencies.

A specialized search-and-rescue## helicopter took fire, their crew injured.# Helicopters needed to be refueled mid-mission.

And an A-10 providing close air support was# struck and had to be ditched over Kuwait.

DONALD TRUMP: Hundreds of people could have# been killed, so we had people that were within## the military that said this is not a wise --# and I understood that, but I decided to do it.

NICK SCHIFRIN: That's when the U.S.

deployed# decoys to confuse Iran about the weapons service## officer's location.

And the CIA helped# find him, said Director John Ratcliffe.

JOHN RATCLIFFE, CIA Director: In addition to# the human and technical assets deployed by## the president to find our airman, CIA executed# a deception campaign to confuse the Iranians,## who were desperately hunting for our airmen.

NICK SCHIFRIN: Secretary Pete Hegseth today## explicitly compared the aviator# to Jesus Christ's resurrection.

PETE HEGSETH, U.S.

Defense Secretary:# Shot down on a Friday, Good Friday,## hidden in a cave, a crevice, all of Saturday,# and rescued on Sunday,flown out of Iran as the## sun was rising on Easter Sunday, a pilot reborn# all home and accounted for, a nation rejoicing.

NICK SCHIFRIN: But, tonight, the nation of Iran is# bracing for escalation, as President Trump said,## the entire country can be taken out in one# night, and that night might be tomorrow.

For the "PBS News Hour," I'm Nick Schifrin.
