Tonight breaking news. The massive explosion at a busy U. S. Canada border crossing. What we learned just before coming on the air with millions of Americans on the move this holiday. And breaking news from Israel on the plan to release hostages. First, the explosion on the US. Side of the Rainbow Bridge. A border crossing linking the US.

For family now awaiting word late word today about the high stakes negotiations going down to the wire and after Israel claimed Hamas was running a command center under Gaza's biggest hospital. Matt Gutman with the IDF. As they go inside the tunnel underneath.

I'm not sure if that side is completely secure yet.

Was there a command center, as Israel claims? Here at home, security is top of mind, with millions on the move on this, the day before Thanksgiving. Crowded roads, packed airports, and what's expected to be the busiest day for the TSA in history. Giobenitez reports the major new storm threat we're tracking sweeping across the country just in time for Sunday's big travel day. Rob Marciano times it all out.

From ABC News world headquarters in New York, this is World News Tonight with David Bjorn.

Good evening, everyone. Thanks so much for joining us on this busy Wednesday night. I'm Lindsay Davis, in for David. We begin with breaking news along the US. Canadian border. A tent scene there after a car crashed and exploded on the Rainbow Bridge near Niagara Falls. Authorities then closed all four international border crossings between western New York and Canada. The chaos is unfolding as tens of millions of people travel for the Thanksgiving holiday. The car slammed into a secondary security checkpoint and then burst into flames. Authorities say it happened on the US. Side of the bridge. Sources tell ABC News the driver was speeding up to 100 miles an hour when the car crashed into the checkpoint. Two people in the car were killed. Buffalo airport is closed to international flights. Police are checking all vehicles for possible explosives. Just a short time ago, the governor of New York revealed there is no indication this was a terror attack. The White House is monitoring the situation. The incident comes as authorities across the country are on a state of heightened alert because of the Israel Hamas war. ABC's Trevor Alt leads us off from Niagara Falls, New York.

This is the moment the car burst into flames. The verified video circulating online showing the deadly explosion raising alarm on both sides of the border on one of the busiest travel days of the year.

I've never seen anything like this. The car just exploded.

It happened just before noon near the New York entrance to the International Rainbow Bridge, which connects the US. And Canada. At Niagara Falls, the car speeding so fast, eyewitnesses say it launched into the air near one of the security checkpoints. I seen something airborne.

I first thought it was an airplane. Looked like slow motion. And I said, My God, it's a car.

Then a fireball.

Yo. Oh, my God. Are they all right?

Smoke billowing high into the air. The driver and passenger dead on the scene. Border officer injured. Authorities sealing the area.

I'm going to send you over to the Custom Bridge for a fire that's happening. Fires are already there. You're going there to block off roads.

Officials in the US. And Canada taking no chances, quickly closing all four bridges connecting Canada to western New York.

Additional measures are being contemplated and activated.

At all border crossings across the country.

We are taking this extraordinarily seriously.

At the airport in nearby Buffalo, international flights suspended. The FBI launching an investigation. New York's governor tonight saying no explosives have been found. Offering these words of reassurance.

I want to be very, very clear to Americans and New Yorkers at this time, there is no indication of a terrorist attack. She's trying to really make that point clear. Trevor Alt joins us now from the scene in Niagara Falls, New York. And Trevor, Governor Kathy Hoekle says there's no indication this was terrorism, but she also warns the investigation could take a while. That's right, Lindsay. And the governor did reveal one of.

The people in this car was a resident here in western New York. But given the size of this explosion, this is a really large scene. This investigation could continue for quite some time.

Lindsay.

Trevor. Thank you. Now to the Israel Hamas war and the planned ceasefire and hostage release. Late today, Israel said nothing will take place before Friday. The Israeli military unleashing massive assaults on Gaza until then. Today, Israel revealed what it claims is more evidence of Hamas working out of Al Shifa Hospital in Gaza. Our team with new images inside the tunnels under the facility and what they found underground. Israeli authorities screening our footage, but only asking sensitive details, such as monitors or soldiers'faces be blurred. ABC's Matt Gutman reports from Israel tonight.

Just hours before a planned ceasefire in exchange for the release of dozens of hostages held by Hamas, a senior Israeli official now saying that the ceasefire and hostage release won't happen until Friday. That is. A relentless Israeli bombardment today left Gaza smothered in smoke. Israel unleashing a massive bombardment on a city already in ruins. Israel and Hamas today hammering out the final details for the release of at least 50 Israeli women and children held in Gaza in exchange for a four day ceasefire and the release of at least 150 Palestinian women and minors jailed in Israel, as well as increased humanitarian aid into Gaza. President Biden personally involved in negotiations. That is a senior US official telling ABC News three Americans are expected to be among the first hostages released, including three year old Abigail Moore. Idan abigail was still in her father's arms when Hamas terrorists shot him dead. She turns four on Friday.

I pray, we all pray, that this release will happen and that Abigail will actually be home to celebrate her fourth birthday in Gaza.

Word of that pause in fighting met with relief. Tala Herzala and her family fled Israel's bombardment in northern Gaza, showing us the horrors of daily life there.

This is what we hear. It's every minute, every hour, every second.

Tala now concerned about what comes after the ceasefire.

I know it's good for people, I know it's good for everyone to stop bombing at least. But it's not enough.

Today, as we drove into Gaza on those Humvees, it's hard to take in.

The scale of the destruction here in Gaza City.

We passed the humanitarian corridor, those civilians standing still as statues, holding up ID cards and white flags. The IDF seven Brigade, taking us into Gaza's largest hospital. Akshifa and inside the tunnel complex, they say, proves Hamas ran a command and control center. Right beneath the hospital and right beside the compound's internal medicine building. We descended into that pit, squeezing into one of the tunnels there. This is the tunnel. You can see it look like electricity cables here. This, we're told, is for air. It led directly beneath that internal medicine building. We're calling this a really sophisticated tunnel. It's high, it's relatively broad. You can walk standing up. You can see all the outlets for electricity and others. The tunnel was vented. This appears to be a kitchenette. You can see it's even tiled here. There is a sink. We saw multiple bathrooms here. You can see the room right next to it. That large room also tiled beds in the back. It even had an air conditioner. Do we know how far this goes?

Couple hundred meters.

Couple hundred meters on the other side?

Yeah.

I'm not sure if that side is completely secure yet. There is so much destruction. How much of it was actually militarily? Because a million and a half aren't going to be able to come back here.

Israel is not fighting against it's, not fighting in order to create destruction. But when you have an organization that wages his war from hospital building tunnels underneath, we have no other alternative. We're going to defeat Hamas.

Let's get right to Matt Gutman. Live in Tel Aviv. Matt, what more are you learning about this possible delay in the release of more hostages from Gaza?

Lindsay, it's unclear what precipitated this change. We understand that both sides had agreed for the ceasefire to begin tomorrow morning, for hostages to be released at some point after that. And we understand that broadly, the deal is still on. About the only thing that is certain tonight is that for the families of the hostages who don't even know that their loved ones are on that list, tonight is going to be a sleepless night, Lindsay.

High anxiety, for sure. Matt, our thanks to you here in the US. Millions of Americans are on the road and in the air at this hour for what stands to be the busiest Thanksgiving travel week ever. Steady flow of travelers snaking through Boston's Logan Airport today. The CSA is expecting a record number of people to be screened at the airports. Traffic on the highways at its peak over the last 24 hours. Nearly 50 million people driving over this holiday. Sunday is expected to be the busiest travel day of the entire week. ABC's giobenitez covers transportation tonight.

Fueled by the lowest gas prices in years, millions of Americans are hitting the road for Thanksgiving.

We stopped at Annapolis. We stopped in New Jersey. Next stop is Rhode Island and then Massachusetts.

Overnight in Los Angeles, a sea of red and white lights as drivers face gridlock on the 405 freeway. While in the east, drivers face powerful storms. This tornado spotted in Hartford, Alabama, this crash in Huntsville, killing two and injuring five. High winds taking down trees in New York City. The system even blanketing parts of New England. In snow at the airport's, massive crowds.

It's a lot busier. I have never seen like this many people.

And we are inside the United control tower here at Newark. And I just want you to take a look at that tarmac because you see all of those planes there. It is very, very busy. 4100 flights for United today. That's three flights every minute. So far, minimal delays, but Sunday could break the TSA's record for the most travelers ever. And, Lindsay, right now is the tail end of the busiest time on the roads here in the Northeast. So now our attention turns to the ride home. The busiest times, according to experts, between three and 05:00 p.m. On Sunday.

Lindsay all right, note to self there, gio thank you. Here in the US, we're tracking a new cross country storm sweeping its way east over the Thanksgiving weekend. Heavy snow in some areas, including the Northeast. Sunday into Monday, which is the busiest travel time of the entire holiday, as he just said. Let's get right to ABC senior meteorologist Rob Marciano. Hey, Rob.

Hi, Lindsay. We're bookending with storms this holiday weekend just as a cold air pours in. This next storm is already in the Rockies, so let's talk about the cold for tomorrow morning. We're going to see wind chills will be below freezing as far south as Huntsville, Alabama. Winds will be blowing around the Thanksgiving Day parade as well, so that could be an issue. But everybody's in the cold and it's cold enough for snow in the Rockies. We've got winter storm warnings and watches that are posted for the Northern Rockies. Here we could see six to twelve inches of snow piling up during the day tomorrow and into the morning on Friday. And then pushing across the Corn Belt through Iowa and into Chicago and St. Louis could see maybe one to three inches of snow during the evening, Saturday into Sunday morning there, and then pushing into, to the northeast with more in the way of rain and some northern snow late in the day on Sunday. So that's where we can see more in the way of travel at those airports. And as both you and Geo mentioned, it's likely to be, according to TSA, the busiest travel day at American airports on record.

Lindsay could be a rough ride home from Grandma's house. Rob, thank you. Next tonight, the deadly avalanche in southeast Alaska. Search and rescue teams are looking for victims caught in the massive landslide. At least three people killed, several more missing. The slide about 450ft wide, slamming into homes and cutting off a highway leading to the small remote town. Here's ABC's Jacqueline Lee.

Tonight, an urgent search by land and by air after a massive landslide struck this remote community in Alaska, southeast of Anchorage.

We are estimating it's about just a.

Little under 500ft across where it crossed the road.

The debris field barreling down this mountain and into the Pacific Ocean on Monday night after a storm brought heavy rain and wind to the area. Governor Mike Dunleavy issuing a disaster declaration. Officials in Wrangle say at least three people were killed and three remain missing, including two under the age of 18. A woman pulled from the debris is now recovering.

That female lived in one of the residences that was on the mountain side of the highway.

The landslide destroying at least three homes and cutting off the community's only highway into town. Dozens of residents also displaced or without power. And Lindsay, officials warn about the possibility of additional landslides as another storm is set to roll through the area tonight, through tomorrow.

Lindsay. All right, Jacqueline. Thank you. Tonight, authorities have released disturbing body camera video of a deadly confrontation with police in Atlanta. A deacon died after being tased by an officer following a traffic accident. The Georgia Bureau of Investigation has launched its own independent probe. Here's ABC's ariel Reschef.

Sign the ticket.

Tonight, calls for justice after the release of this disturbing body camera video showing the tense moments that led to the Tasing death of an Atlanta deacon.

Sign the ticket. I'm gonna TASE you. Put your arms while you're back now put your arms around your back.

According to the family, deacon Johnny Holman was on his way home from Bible study on the night of August 10 when he was hit by another driver. Holman calling 911.

Somebody ran to my truck right here.

Officer Kieran Kimbrough informs Holman he was found at fault, but Holman asserts his innocence, refusing to sign the traffic ticket.

I ain't doing nothing.

The officer attempts to take the 62 year old into custody, struggling for several minutes.

Okay, put your hands on your back. Okay.

He then deploys a taser. Holman unresponsive EMTs called to the scene. The deacon transported to the hospital, where he was pronounced dead. The medical examiner ruling Holman's death a homicide, saying he died due to the shock from the Taser. Tonight, Holman's family calling for Officer Kimbrough to be charged.

We need him jailed. We need him prosecuted to the fullest extent.

Lindsay. That officer was terminated for violating department procedure. His attorney says he denies any wrongdoing and has appealed his firing.

Lindsay. Ariel. Thank you. When we come back, the fiery plane crash in Texas. What we're now learning, and the legal battle lines are drawn between one of the most iconic duos in rock history. Holla notes next. Tonight, the NTSB and the FAA are investigating a fiery plane crash in Plano, Texas. And a warning the images may be disturbing. The 87 year old pilot was the only person aboard the single engine Cessna. He was killed when the plane slammed into a shopping center parking lot. The aircraft was quickly engulfed in flames. No one on the ground was hurt. A somber anniversary today marks 60 years since the assassination of President Kennedy in Dallas. Generations of Americans remember where they were on November 22, 1963, when news broke that Kennedy had been killed. Today in Dallas Parkland Hospital opened the John F. Kennedy park for Hope, Healing and Heroes. Kennedy was rushed to parkland by the Secret Service after he was shot. When we come back, the legal battle lines are drawn between one of the most iconic duos in rock history, hall and Oates, and the animal shelter that's finding homeless for the residents during this holiday season.

Fans of Holland Oates may be asking, say it isn't so. The 70s pop duo, one of the most successful in history, is battling it out in court. Darryl hall is asking for a restraining order against John Oates, which the judge granted. Details of the case remain sealed. Hall and Oats were inducted into the Rock and Roll Hall of Fame in 2013. When we come back, the animal shelter bringing its residents a home for the holidays. Finally tonight, America Strong, the animal shelter that's getting some a home just in time for the holidays.

On this Thanksgiving Eve, some families in Richmond, Virginia, are serving up an extra helping of gratitude to their four legged friends in need. This week, Richmond animal care and control kicked off their Thanksgiving foster program. Now nine years strong, their goal is to find a home for them all just in time for the holidays. And every Thanksgiving, the shelter's population has reduced by as much as 75% the first official adoption of the Thanksgiving program ice cream cake and her family, the gardeners.

We'd like to thank the team at Richmond animal care and control for introducing us to our new member of our family.

Ice cream cake joy comes in all sizes, and for that, they are positively thankful. Like Baconator and his fosters, Teddy Gray and Lola Holmes and Emma Jones and her daughters taking home the pit bull hotel Transylvania.

He is going to be happy.

She's a very sweet dog.

Many of these furry friends already feel right at home, even before they hit the doorstep. And tonight, director, Kristen Peters on what the program means for the staff.

It's just a really incredible morale boost. It's so nice to see a really happy ending time and time and time again.

Emptying out this shelter is a blessing, and nothing quite shows their gratitude like a good lick on the ear.

That puppy love. Thanks so much for watching and happy Thanksgiving. I'm Lindsay Davis. I hope to see you right back here tomorrow. For David and all of us, good night.

Thank you for making world news Tonight with David Muir, america's most watched newscast.
