AMNA NAWAZ: Let's go now to special correspondent# Reza Sayah in Tehran.

Reza joins us on the phone.

Reza, now this third straight day of# U.S.

and Israeli strikes in Iran.

Just## give us a sense of what you're seeing and# what you're hearing on the ground there.

REZA SAYAH: Amna, as I'm talking# to you right now, I'm hearing the## unnerving sound of jet fighters flying over# Tehran and massive earth-shaking explosions.

They started around 12:00 midnight local time,# and it's continued for the next 90 minutes, so,## again, multiple explosions in what sounds like# anti-aircraft.

And one other thing that I need## to point out is, around 1:30 a.m., the Internet# access was cut off.

And that's kind of unusual.

When this war started, the government cut# off the Internet.

There was only access to## the national network.

It was a closed network.# But using VPN, virtual private network, I was## able to get access to the international network.# That stopped around 1:30 am local time.

Was it## related to these latest airstrikes that started# around midnight?

It's not clear, but no Internet.

That's why I'm talking to you on the phone.# Earlier today, more airstrikes, intense## airstrikes targeting the heart of the city.# Israeli officials have repeatedly said they're## targeting the security apparatus, buildings# related to the military, Revolutionary Guard.

But, increasingly, we are seeing on the# ground non-military targets either being## hit or severely damaged, hospitals.

We had a# school on Saturday.

Earlier today, I went to## a major square here where a police# headquarters was hit.

The police## station was destroyed, but surrounding# it were scores of residential buildings.

They too, they were either destroyed or severely# damaged.

I went to a cafe across from the police## station, talked to a patron there who was there# during the airstrike.

He was smoking a hookah## when the missiles hit.

He showed me some gruesome# video of a fellow patron with his head severed.

And he described what sounded like a# double-tap strike, where he said the## initial strike wasn't much, wasn't much# of an explosion, a few minutes later,## massive explosion.

And that gives you an idea# of the cycle of violence we're experiencing.

AMNA NAWAZ: Reza, let me ask you about# what we have heard from U.S.

officials,## because President Trump claimed yesterday# that Tehran had reached out to talk and## to negotiate.

Today, he warned of a -- quote,# unquote -- "big wave" of strikes yet to come,## and he didn't rule out U.S.

troops on the ground.

What's been Tehran's response to all of this?

REZA SAYAH: Tehran's response is no# talks and they're going to keep fighting.

Just keep in mind, from Tehran's point# of view, there's no trust.

This is the## second time they're in the middle# of negotiations.

Without warning,## they have been under attack.

And they# have tried to project resilience.

Ali Larijani, the secretary of# the National Security Council,## in a statement saying they're not going to# negotiate with terrorists.

The foreign minister,## Abbas Araghchi, saying that they have learned# lessons from U.S.

defeats in the region,## and they're going to use these lessons in this# war.

They're going to decide how the war ends.

So they're projecting resilience,# toughness.

And seemingly, in the## region, they're carrying out an aggressive# campaign targeting U.S.

bases, U.S.

assets,## Gulf states, military bases.

And they're also# saying they're targeting hotels because they## have intelligence that U.S.

servicemen# have left the bases to go to the hotels.

AMNA NAWAZ: That is our special correspondent,## Reza Sayah, joining us tonight# on the phone from Tehran, Iran.

Reza, thank you.
