And the dog, once called unadoptable, now All starring at the Westminster Dog Show. From ABC News, World headquarters in New York. This is World News Tonight. Good evening. Thanks for joining us on this Saturday. I'm Whit Johnson. As we come on tonight, hundreds of thousands of Palestinians are being ordered to leave the city of Rafa in Southern Gaza. The Israeli army preparing to expand its ground operations amid a widening rift with the United States. In Raafa, families gather gathering their belongings, many of them displaced multiple times. The city had been a refuge for more than a million people, fleeing the fighting from other parts of Gaza.

President Biden, standing by his warning that the US will not provide offensive weapons that could be used in Raqqa. Today, the death toll rising with more Palestinians killed in IDF strikes. We have team coverage tonight, and ABC's Marcus Moore leads us off from Israel.

Israeli forces tonight pushing deeper into Southern Gaza City of Raqqa. 300,000 people now on the move amid new evacuation orders by the IDF as they position for an expanded ground operation. The IDF telling people currently in Raqqqa to evacuate to an expanded safe region roughly four miles away. But aid groups say that area, too, is already overpopulated. Mohamed Abu Al Qass is a pediatrician in the Gaza Strip. And since the start of the war, he says he's moved his family several times at the direction of the IDF. At and is now moving once again. In the time of war, there's no place that is safe, he says. We expect strikes everywhere. At least 18 Palestinians were killed today in IDF air and artillery strikes on neighborhoods in East and West Ra'afa, according to a local hospital. The Hamas run Gaza Health Ministry, saying since October seventh, the fighting has claimed the lives of nearly 35,000 Palestinians. All as the flow of supplies going into Gaza has slowed, according to aid groups. It has stopped almost completely in the south. We were near the Kerem Shalom border crossing as demonstrators tried to stop aid trucks from passing through earlier this week.

This is where aid trucks come through every single day with crucial food and supplies for those starving in Gaza. But these demonstrators are stopping them right here. However, aid groups say the humanitarian situation there is only getting worse as the war in Gaza enters a new phase. There is no definitive date on any potential operation, but the Israeli Prime Minister has said that they will expand their fight in Ra'afa. Where, as you know, President Joe Biden has stopped some weapons deliveries, saying the US would not provide weapons to Israel if they launch a full scale assault on Ra'afa.

Marcus Morth Thank you. And as you noted there, the US has ordered Israel repeatedly not to invade Raqqa because of the risk to civilians. Let's bring in ABC's White House Correspondent, Mary Alice Parks. Mary Alice, what are you hearing from US officials now?

With the White House is monitoring all of these developments extremely closely. So far, they say they've only seen a limited military operation into Raafa. They're not commenting more at this time about Israel ordering civilians to evacuate. But we know that President Biden himself has been pushing Israel to do anything but a full-scale invasion of Rafa. I'm told the White House has been presenting the Israelis with several alternative options, even offering to help set up safe spaces for civilians or give additional intelligence to help target Hamas leaders or pinpoint their tunnel systems. But as you saw there, no indication that Israel is changing course.

Mary Alice, thanks. And tune into this week, tomorrow morning, Martha Radetz interviews top Biden ally, Senator Chris Coons, and the Republican Chair of the House Foreign Affairs Committee, Michael McCall about the state of the war in Gaza. Now to the Race for the White House, former President Donald Trump hitting the campaign trail with a rally tonight on the Jersey shore. Earlier, Trump announcing on social media that former South Carolina governor Nikki Haley would not be his vice presidential pick, shutting down any previous speculation. Here's ABC's Perry Russa.

Tonight, former President Trump trading a New York City courtroom for the beaches of Wildwood, New Jersey.

We have to set high standards because this country has never been in a position like we're in right now. We're left at all over the world.

A rare campaign rally as he spends his weekdays defending himself in his felony hush money trial. Trump has denied all charges. Many here tonight still standing behind the former President.

If it was such a big deal, they should have dealt with it then, not now.

They want to make him look bad.

They want to smear his name.

Our latest ABC news, Ipsos Polling, finds 80% of Trump supporters say they will still support him even if he's convicted. 16% say they will reconsider, and 4% will withdraw their vote entirely. If he's found guilty in that trial, would that change your vote at all? No, it won't change my vote at all. As Trump trails President Biden in cash on hand. Tonight, the New York Times and ProPublic are reporting on an IRS audit, which they estimate may cost Trump $100 million if the IRS prevails from allegations of, a dubious accounting maneuver to claim improper tax breaks from his tower in Chicago. Abc News has not confirmed the reporting. Trump's son Eric telling ABC News this matter was settled years ago, only to be brought back to life once my father ran for office. We are confident in our position, which is supported by opinion letters from various tax and experts, including the former general counsel of the IRS.

You have to look at yourself as a person.

Are you a perfect person?

Is he a perfect person?

No one is perfect except for the man upstairs.

With this is the chance for Trump to get back in front of his base. There are thousands of people here, one of the larger crowds he has had recently. Some people lining up on the boardwalk since Wednesday just to be here with.

Perry Russam, thank you. We want to note that this is your first report for us on World News tonight. Welcome to the team. It's great to have you. We appreciate it. We do move on now to Michigan, where the attorney general is investigating a police pursuit and collision that led to the death of a suspect outside Grand Rapids. Body camera video shows officers responding in an unmarked police car, hitting a man, pinning him up against a fast food restaurant. He later died at the hospital. Tonight, his family is calling for justice. Abc's Morgan Norwood has details, and we want to warn you, the video is disturbing.

Tonight, the Michigan attorney general is combing through this disturbing, newly-release, body worn camera video showing the moment a Michigan state trooper in an unmarked squad car plowed into a suspect running away. The incident happened on April 17th, when state police say fugitive task force officers were chasing Samuel Sterling, who they say ran off as they were trying to bring him in on outstanding warrants. Seconds later, an unmarked police SUV slams into Sterling. The 25-year-old wailing in agony.. Sterling was taken to the hospital where he died just hours later. His family saying, tonight, they're stunned and appalled. His heartbroken mother speaking through tears.

I don't know how my leg going to go off without my side.

Tonight, the attorney for that unidentified trooper saying, The trooper involved is heartbroken broken at the loss of Mr. Sterling's life and wants the family to know that he had no intention of purposely harming Mr. Sterling. With the Michigan attorney general, we'll decide whether that trooper will face any charges. The state's governor says he remains on unpaid administrative leave. Norton, Norwood.

Norton, Norwood. Thank you. In Northwest Florida, tonight, the cleanup is just getting started in the wake of powerful storms packing hurricane force winds. At least one person was killed, homes and businesses destroyed, thousands left without power. Court, the governor declaring a state of emergency in 12 counties. Here's ABC's Faith Abube.

Tonight, we're learning more about heroine stories of survival after that deadly multi-day severe weather outbreak striking much of the country. In Jackson, Mississippi, Latanya Williams and her family thought it was safe to go to sleep early Friday morning. The storm had passed.

Around 12:30, I would say, that's when my husband heard the creaking, and we jumped up and ran.

That sound a neighbor's tree about to crash into their home.

By the time we ran out and made it around this first corner in the hallway, that's when the tree came through the bedroom.

And north of Pensacola, Florida, this is what's left of where Mike Stout's daughter lives. He says she and her husband were thrown from their home when powerful wind struck.

She said she was up watching the weather, had her phone in the hand. Then all of a sudden, they weren't in their room anymore.

Luckily, they had only minor injuries. And in Tallah O'Hasie, the Florida State University campuses remained closed after storm damage there and in surrounding neighborhoods. Officials saying classes will be held Monday. With the National Weather Service, since April 25th, it has confirmed more than 250 tornado in at least 19 states and received more than 2,500 reports of severe weather across an even wider area.

Yeah, that widespread destruction for days. Okay, Faith Abube, thank you. Let's bring in the ABC news meteorologist tomorrow. Theodora and tomorrow, Theodore, and tomorrow More strong storms on tap for Mother's Day.

That's right, went in. The biggest threat with these storms is flooding. Take a look. This is the excessive rainfall map, the greatest flash flood threatened red from Waco to Tyler on Sunday. This threat continues into Monday moving farther east. Timing this out, tomorrow night, Mother's Day, heaviest rain hitting areas previously hit hard like Houston. Monday night, that then shifts to the Florida Panhandle by Wednesday, arriving in the northeast. Not a big flood issue in the northeast. However, We could see some soaking rain. By the time this all is all said and done in the Gulf Coast states, we could see 5 to 10 inches of rain.

We know you'll be tracking it tomorrow on GMA. Tomorrow, thank you. Now to the rare light show in the sky and the potential threat to infrastructure here on Earth. A series of powerful solar storms creating an unusual treat for millions of Americans. The Northern lights visible for much of the country, as far south as Florida and Texas overnight. And what's expected for the rest of the weekend. Here's ABC's Ica Joshi.

Tonight, the stunning images of the Aurora Borealis, better known as the Northern lights, visible across much of the country. Crowds gathering along Puget Sound outside Seattle. Wow. The lights, typically visible in Northern latitudes now seen as far south as the Florida Panhandle, and in Texas, outside Austin. They're caused by unusually strong solar outbursts reaching the Earth.

When the sun sends out material aimed at the Earth, that material can interact with the Earth's magnetic field, and that is what results in a geomagnetic storm.

An extreme-level storm, the highest category in the first since 2003, reaching the Earth Friday, and again today. And that can pose a real threat.

Changing magnetic fields create electric currents, which can blow out our power lines, our power supplies, damaged satellites.

The first solar flares erupting earlier this week, directed towards Earth from the Sun's Corona. The Corona, visible from Earth with the naked eye, only during a total solar eclipse impacts, like the one that occurred across the US last month. With the Space Weather Prediction Center has issued a geomagnetic stormwatch for tomorrow. Now, weather permitting, much of the US will be able to see those northern lights again tonight.

With? All right, we're hoping for that, Ike. Thank you. Protests on college campuses across the country continue to have an impact on graduation season, now in full swing. You see Berkeley's commencement repeatedly interrupted today, and dozens arrested overnight. You see this large crowd breaching a gate at the the President of the University of Pennsylvania. Police then rushing in. Turning now to the housing market in the US, and anyone who's trying to buy a home recently knows that prices are soaring. That's leading some to question whether another housing bubble is about to burst. Abc's Alexis Christofferis breaks it all down.

Tonight, home price is soaring across much of the country despite higher mortgage rates, which should lower demand and push prices down.

If you look at any Any affordability metric, it is flashing at least a yellow, if not a red signal. Housing is expensive.

A recent realtor. Com survey found nationally, buyers need to make about $116,000 a year to purchase a typical home. Prices up a staggering 40% in just the past four years, putting homeownership out of reach for many.

It used to be late '20s or early '30s when people became first-time home buyer, but now it's becoming in the mid '30s or even late '30s.

The persistent a lack of homes for sale keeping prices high. Many sellers staying on the sidelines, thanks to what economists call the lock-in effect. Homeowners unwilling to sell and give up the ultra-low mortgage rates they locked in just a few years ago. A $400,000 home in 2021, when mortgage rates were just below 3%, meant a monthly payment of nearly $1,700. At today's rate, that same home is about $1,000 more each month. Home prices defying gravity nationwide, especially in the Northeast, where prices are up 11% from a year ago. That has some declaring we're in a housing bubble. But experts say not so fast.

Prices are being driven by supply and demand. We don't have those irrational reasons of funny, risky mortgages in the marketplace, and therefore, the housing market is on solid foundation.

Financing a home is not expected to get much cheaper. Experts I spoke to expect mortgage rates to end the year slightly lower at 6.5%. In another blow to consumers' wallets, a federal judge has blocked President Biden's attempt to cap credit card late fees at $8, calling the rule unconstitutional.Witt.Alexis.

Christofferis for us tonight. Thank you. There's still much more ahead on World News tonight. This Saturday, including the latest on a deadly shooting inside a movie theater. And later, the unlikely rescue dog now wowing the crowds at the Westminster Dog Show. Next tonight, devastating floods in Northern Afghanistan. More than 300 people have been killed, more than a thousand homes destroyed. The World Food Program has begun distributing aid to the hardest-hit areas. Seasonal rains have been unusually heavy, and this comes as Afghanistan is still recovering from a string of earthquakes earlier this year. In Ohio, one man was killed in a shooting inside of a movie theater. This happened late Friday night in the lobby of a regal cinema, about 50 miles south of Cleveland. One suspect was taken into custody Police have not said what led to that shooting. When we come back, a scary moment when the number one tennis player is hit with a bottle. How he's doing tonight. To the index now, a lot of tennis fans were left holding their breath when the world's number one player, Novak Djokovitch, was hit in the head with a water bottle as he was signing autographs at the Italian Open on Friday.

Organizers say the bottle fell from someone's backpack and he wasn't seriously hurt. Today, Djokovitch returned wearing a bike helmet and posting, Today I came prepared. When we come back, every dog has its day, right? And this one has a remarkable story. Finally, tonight, America Strong, the underdog we just can't help rooting for. Tonight, an unlikely star at the Westminster Dog Show, a rescue mut named Miles, taking the agility competition by storm. But six Six years ago, his future looked bleak until Christine Longnecker showed up at this Pennsylvania shelter.

It was just staring at me with these liquid brown eyes, and I was like, That's it. That's the dog I'm taking home. And the shelter had been like, I don't know if you really want that dog. He'd been returned a couple of times, but I said, No, he's getting in the car with me. And now here we are at Westminster.

Christine, a horseback riding instructor, would take Miles along for the lessons, where he found his calling.

The horse jumped the fence Before I knew it, Miles had taken off from my side and ran out and jumped the jump with the horse. And I was like, Oh, wow.

So Christine started to train Miles for agility competitions.

Jumping comes insanely naturally to him.

Soon Miles began racking up some wins, leading to this special moment today. The first of his Westminster runs, Christine leading him through. And while Miles did not make tonight's finals, he's winning hearts across America.

To everyone else, he's an underdog. He was unadoptable, but anybody who spent any time with him knows that there's nothing underdog about him. He loves every day of his life, and we could all take a really big life lesson from him.

All he needed was a chance, and he's making the most of it. Way to go, Miles. I'm with Johnson in New York. Have a great night.
