03/07/2014 ABC World News with Diane Sawyer

Welcome to World News, tonight, News with David Muir.

Welcome to World News, tonight, breaking down, tropical storm Arthur

barrelling towards the east coast, set to become a hurricane before the

fourth. Our team is on the coastline. Our meteorologist has the

new storm track coming in now. Breaking news, new terror fears, US

authorities calling for new security at airports around the world.

Tonight, what are they so worried about? The food truck fireball

caught on tape, families were lined up for dinner. Tonight, we have

learned what caused it and the urgent warning for anyone grilling

this holiday. Good evening, it is great to have

you with us on Wednesday night. Millions of Americans are watching

this tonight, the monster tropical storm growing by the hour, the radar

right behind me is turning off the coastline tonight. It could not come

at a worse time, hurricane warnings going up as we come on at night.

Look at the view from space, Arthur is 450 miles wide, wins are at 80

mph, and that is just the beginning. With the force of `` with the 4th of

July on the way, many areas are expected to be hit hard. Dutch wins.

Firstly, let's get right to it. Our meteorologist has been looking at

this. `` winds. We are 400 miles away from the Carolina coast, this

is the area we will be most concerned about. Hurricane

warnings, and a mandatory evacuation put in place will stop all of the

city is here, and the red, that is what we are concerned about. It is

for tomorrow night, and early Friday morning. Have a look at this, as we

watch the past, this will happen overnight. This could be our first

hurricane of the Atlantic season, skirting by early on Friday morning.

Then, it goes off to see. A lot of the East Coast will miss out on it,

a big reason is the water temperature. You need 80 degrees to

fuel a hurricane, but as it goes to the 70 and 60 area, it will kill it.

It will put it together in a future cast. Here is how it will play out,

North Carolina, onshore, midnight Friday. Parts of New York and

Washington, DC will be wet, drying up by Friday night. Connecticut and

Boston will have problems then. We learned that Boston have moved

fireworks up by a day. But shoots you how widespread it is? `` that

shows you. Absolutely. One of the real dangers of this, as you have

pointed out all day today, the rough seas, rip currents, our

correspondent is in Florida, with the rescue teams getting calls

today. That is right, Arthur is turning out 100 miles or more that

way. It is bringing in bands of wind, rain, blowing up the see

behind me. The hidden danger is not so much these waves, but what is

underneath. Tonight, a high rip current risk, declared along nearly

500 miles of US coastline, from Florida to South Carolina. This

afternoon, a call came in, and we were with Ocean rescue in Daytona.

They found someone caught in the riptide. Here on the beach, like

millions of Americans this weekend, people playing in the surf. Despite

that, a silent killer is lurking nearby. What we are seeing here, a

channel forming. Now, it is a rip current. That is what it is, a

channel forming in the sand bar. Officials warned us today that they

can pull even a strong swimmer out to sea. When you add the die, you

can see it. Now you see it, now you don't. If you are caught, swim

parallel to the shore until you are free. The current was too much for

these five goals yesterday, they were paddle boarding off the coast

of Florida, and slammed into the rocks. I thought I would die. I

couldn't breathe. Rescuers were forced to save them. Rip currents,

storm surges, and flooding, they are reasons that North Carolina declared

a state of emergency. Let's hope and pray for the best. Again, do not put

your stupid head on, be smart. I want to show you something that you

cannot see with the naked eye, to the side of this PR, a rip current.

Rescuers here say that 60,000 people a year are saved, if you insist on

going into the water during the storm, stay close to lifeguard tower

is like this one. `` pier. A state of emergency declared in

North Carolina already. We live with more on the mandatory evacuations

already under way. The first order for the entire coastline that under

the hurricane warning tonight. It couldn't come at a worst time.

Businesses along the speakers depend on these weekends for a lot of their

money. So far, no mass exodus. `` along these beaches. 250,000 people

come to North Carolina beaches. Businesses expect about a 25% hit.

As you heard the governor say, don't put on your stupid hat. Safety comes

first. Well set by the governor. `` said. In California tonight,

wildfire they are baffling, this time in the Napa Valley. They are

battling the fast moving blaze. Officials say the hot weather is

making the fire explode in size. At least 200 homes evacuated already.

Late today, US authorities called for new security precautions at

airports around the world. This new concern terrorists are plotting now.

First of all, these new security measures, what are we talking about?

Homeland Security is asking some airports overseas to expand their

screening of passengers before flying to the US. Sources say to

look for: What do they know about the plan and

what are they concerned about? This is about fear that somebody

might smuggle bomb onto a plane heading to the US.

Authorities say some innovative bomb makers from Yemen appeared to be

teaming up with thousands of Al Qaeda fighters in Syria. Many are

from Western countries and they could have easy access to the

homeland. Today, a 19`year`old woman from Denver was arrested for trying

to join fighters in Syria. Thank you. Now to that potentially

explosive scene from the south. The showdown near the border. You will

remember images from last night, buses filled with immigrants headed

to a processing centre in southern California. Angry protesters at

stopping the bus and forcing them to turn back. Some of the passengers

were filmed. Many passengers came across without parents. We will hear

from the Mera `` the mayor of the town.

In the dead of night, a border patrol bus filled with 140 central

American immigrants tries again to find safe harbour. Mums and children

onboard, fresh from the illegal crossing, turned away in California.

The roadblock. The immigrants sent here because border patrol

facilities in south Texas are jammed. But this California town

said no. We would have potentially 500 immigrants on the streets, we

don't have the resources to handle. The town fears that the border

patrol holds them long enough to be processed and then, as we saw,

releases them at local greyhound stations where they are free to go

anywhere. This is an international bus station, with plenty of buses

going south to Mexico. But there's a line there. The only line is here.

`` there's no line there. Because these buses are going north to the

US. The higher? Memphis. Texas? Kentucky. Melissa bought her

five`year`old son on the journey. Starting in Honduras, in eight days

on a bus through Mexico, across to Texas. Four nights in a border

patrol processing centre and then by bus to Maryland. All with just one

promise. Show up in court today at 10am in the morning in Baltimore.

We were there. She was not. She wasn't at the Maryland address she

gave. Border patrol forces say fewer than 20% ever show up as promised.

How many of them are going to turn themselves involuntarily once they

have been released? That map was I opening. From

Honduras, to Texas, Maryland and authorities have lost track?

That's the problem and that's why the president says he needs billions

of dollars to build more detention centres and to get more immigration

judges to process these people faster. The administration also says

the real cure is immigration reform. The debate rages on. Thank you.

Around the world and first Israel. New fallout after three teenagers

were found dead, one a US citizen. An Arab teenager has now been found

dead, the apparent victim of a revenge killing. Benjamin Netanyahu

already took action, in dozens of sites in the Gaza Strip. Tonight,

there are clashes and fights. Two rockets were intercepted fired from

Gaza. Now to the urgent headline from the

World Health Organization, sounding the alarm and holding emergency

meetings after the deadliest outbreak of Ebola.

It killed more than 460 people across three African countries. Our

chief medical editor has studied this up close and looks at whether

the disease could travel here. We saw the deadly power of Ebola

firsthand. The disease is so dangerous anyone going in the ward

took extreme precautions. Not one bit of my body is exposed. We are

making sure that every inch is covered.

Today, the World Health Organization is struggling to contain this

unprecedented outbreak. Spreading in part across the border from three

countries. There is no cure. In this outbreak, 62% of infected people

have died. Ebola only spreads by close contact with body fluids of

infected people. When I visited this award in 2012, whenever a team

touches a patient, they were quickly spread down. I have to say, there

are few things I've done in medicine that are as nerve racking as going

into this place. Tonight come `` tonight, a you feel `` a new fear.

Some patients avoiding the clinics and continuing to spread the

disease. Many people are wondering if it

could come here. It's a very slight risk. You only

spread the disease when you are very sick and they would never let you on

an aeroplane. But it is possible for a healthcare worker to travel here.

White it would spread around the US, it could be a worldwide problem.

`` while it would spread. Turning to the pictures that came in

late today from Los Angeles. A 30 minute police chase. Top is followed

it all. The suspect eventually facedown in the middle of the

street. Officers racing to the car to make sure nobody was inside. They

believed the suspect had stolen the car and he is now under arrest.

Receiving, just 24 hours after the US' loss at the World Cup, his star

goalkeeper is now a commodity and sponsors are racing to sign him up.

On Wikipedia, he was dubbed: take a look at this.

The real secretary of defense congratulated him. He got a call

from the president as well. Much more tonight. Families lined up or

dinner and then this. The incredible picture. The fireball caught on

camera. We just learnt what started it all and a warning for any family

grilling this 4th of July. And called him the terminator, whatever

you like. He is terrorising Wimbledon but it's

not the players. They keep this hawk hungry on purpose. Coming up.

Next to the food trucks growing more and more popular. One of them

bursting into flames in Philadelphia. We've just learnt the

cause and authorities have a warning.

Keep your eyes on this food trucks. Watch. Without warning, it explodes

into a massive fireball. Look again. Flames spam the street in both

directions, injuring 13 people, among them the mother and daughter

inside the truck. Chaos. I came around the corner, saw flames and

women on the ground. Police believed house was leaking, invisible vapour

lighted by the grilles inside. A propane leak was also blamed for

this blast at a high school. But it's not just food trucks, similar

tanks fuel many backyard barbecues. In 2012, squeals set an estimated

4000 people to the hospital. Our colleague was one of them. A huge

fireball exploded. She relived her grille, igniting an invisible

propane cloud. Propane is a monster and you have to respect it. If your

grille goes out, turn everything off and wait 15 minutes before

relighting. Always keep the lid open when lighting it. Watch what can

happen when gas builds up. Try rubbing something to see if it will

bubble up around the hose. Passengers onboard a Qantas flight

from Los Angeles to Australia got a surprise at 30,000 feet when the

aisles flooded with water. The plane turned back but not before this

happened. Water leak through the ceiling. The crew stayed calm,

handing out blankets so passengers could dry. From Wimbledon, fun

photos of the usual Duchess getting into it. Writing her lip, her

jawdropping. `` biting her lip. Finally, taking aim, it's not the

players he is after, something else. They have attached a GPS to this

hawk could track hawk could track its moves. This

six`year`old court is so well`known here he is the star of his beer

commercial. `` hawk. The problem? Pigeons interrupting the play.

That's where he comes in. This incredible talent comes towards

them, they won't hang around long enough to see if he will have them

for dinner. `` hawk. His weight is monitored down to the exact

balance. Too heavy, he won't want to hunt. Too hungry, he might eat the

pigeons. That's not what they want. Instead, he is simply the official

bird scarer. " He is intimidating. `` up close, he is. His vision is so

precise, if he spotted a newspaper across the field... He would be able

to read the headline. The perfect weapon and a guardian of the games

below. I hope you come back to us tomorrow

night. Good night. It is likely to be the warmest day

of the year so far, with temperatures peaking at 27 degrees

in south`east
