CARL AZUZ, CNN 10 ANCHOR:  A new poll is out on whether Fridays are awesome!  It shows that CNN 10 out of 10 people agree.  
I`m Carl Azuz.
And  our first stop today is in the Middle East.  Officials worldwide are  investigating an attack that happened last week in Syria.  Eighty-nine 
people were killed and dozens more injured in what witnesses say was an  assault involving a chemical weapon.  The U.S. and some other countries  
blamed Syria`s government for it.  Syria and Russia, its most  powerful ally, have denied it, saying terrorist groups were  responsible.

BASHAR AL-ASSAD, SYRIAN  PRESIDENT:  So, there was no order to make any attack.  We don`t have  any chemical weapons.  We gave up all our arsenals a 
few years ago.  Even if we have them, we wouldn`t use them.  And we had never used our chemical arsenal in our history.

AZUZ:   That was a clip from the Syrian leader`s first interview since the  attack was made.  It was distributed by AFPTV, but the organization was  not 
allowed to record the interview.  Syria`s government did.  
President  Assad`s statements contradict the findings of the U.S. intelligence  community.  It said it intercepted communications between 
Syria`s military and chemical experts discussing preparations for last  week`s chemical attack.  U.S. officials have said there`s no doubt that 
Syria`s leader is responsible, but President Assad said the footage  that appeared to show victims of the gas attack came from a terrorist 
organization and he casts doubt on its authenticity.

AL-ASSAD:   About the attack, as I said, its not clear whether it happened or not,  because how can you verify a video?  We don`t know whether those 
dead children were killed in Khan Sheikhoun. Were they dead at all?
(END VIDEO CLIP)
AZUZ:   British and Turkish authorities say they`re testing indicates a type  of chemical weapon was used in the attack.  And experts say only Syria`s  
government would have been able to make that chemical or one like it.
"Primed  and ready for a sixth nuclear test", words describing North Korea from  an organization that monitors the communist Asian country.  Analysts 
from 38 North had been looking at satellite image.  They say the  increased activity at a North Korean testing site, like new equipment  coming in, and 
water being pumped into the area, it all suggests that another nuclear test is imminent.
Even  though the international community considers its nuclear program  illegal, it`s a source of national pride for North Korea and its 
controversial leader, Kim Jong-un.  For foreign journalists allowed  inside the country, getting a glimpse of him is a tightly controlled  opportunity.

SUBTITLE:  CNN sent to secretive North Korea event.
WILL  RIPLEY, CNN INTERNATIONAL CORRESPONDENT:  It`s not even 5:00 a.m. yet.   I got woken up a few minutes ago with a call from our minders saying  that 
we need to put on suits, bring light gear and leave the hotel right now for a major event.
We`ve been given this press bands which we will now have to wear on our arms.
A convoy of buses heading out.  
So, we have been told that we need to leave our cellphones here in the vehicle.  
Now,  we`re here on the street.  It`s completely closed off.  Tens of  thousands of people are moving in here, all signs that the North Korean 
leader Kim Jong-un will probably be here.
The  North Koreans are showing the opening of a brand new street full of  apartment buildings.  They want to show the world, despite international  
sanctions, despite diplomatic isolation, they can still  complete projects like this and they credit one person, their supreme  leader.
The crowd is silent.  There`s very heavy security.  You  can see top Workers Party leadership lined up there.  And when the  military band plays one 
particular tune, that signals the North Korean leader Kim Jong-un is arriving.
Five  years into his role, it is clear that he holds absolute power over this  country.  Relaxed, confident, appearing firmly in control.
And with that, Kim Jong-un cut the red ribbon, walked back to his black Mercedes limousine and drove away.

AZUZ (voice-over):  Ten-second trivia:
Which of these options is located off the northeastern coast of Australia?
The Great Barrier Reef, Tasmania, New Zealand, or the Timor Sea?
Australia`s northeastern coast is near the world`s biggest and longest reef, the Great Barrier Reef.

AZUZ:   1998, 2002, 2016 and now, 2017, these are the years in which coral  bleaching events have been observed in the Great Barrier Reef.   Bleaching 
is when coral losses its vibrant color.  It can turn  completely white.  It doesn`t mean the coral is dead, but it`s a bad  sign for its health.  Causes 
can include pollution, invasive species, low tides and significant changes in water temperature.  
El  Nino, a natural warming of Pacific temperatures, had global effects  last year.  But that`s come and gone.  And Australian scientists who  recently 
conducted aerial surveys say they observed bleaching  over two-thirds of the reef.  Australia has invested more than $1.5  billion to try to protect the 
reef.

IVAN  WATSON, CNN SENIOR INTERNATIONAL CORRESPONDENT (voice-over):  It`s one  of the seven natural wonders of the world.  The Great Barrier Reef off  the 
coast of Australia, a vibrant underwater ecosystem of  coral and sea life that`s roughly the size of Italy, so huge you can  actually see it from 
space.
(on camera):  But  scientists are sounding the alarm.  They say for the second year in a  row, this sprawling underwater treasure is bleaching on a 
massive scale.  A new study by Australia`s ARC Centre shows approximately two-thirds of the reef is affected.
SEAN  CONNOLLY, ARC CENTRE OF EXCELLENCE FOR CORAL REEF STUDIES:  It`s quite  terrifying actually, the magnitude and severity of the event.
WATSON (voice-over):  Sean Connolly is one of a team of scientists who`ve been surveying the damage.  
CONNOLLY:   A coral is a partnership between an animal, which is what builds the  skeleton and constructs the reefs that you see, and the tiny one cell 
algae or plants that live inside it.
WATSON:   His team released footage of barren expanses of coral, bleached bone  white -- in some cases, turning a drab, lifeless brown.  
Look at the before and after contrast of coral gone from healthy to bleached.
Dr.  Nancy Nolton, a coral reef biologist with the Smithsonian`s Museum of  Natural History, says the coral is basically suffering from heat stroke.
The  Great Barrier Reef is more of not just home of thousands of species of  fish, birds, coral, whales and dolphins.  It`s also a major tourist 
attraction that earns Australia $3.7 billion a year.  To add to the bad  news, a big part of the reef that escaped bleaching was pounded by  tropical 
cyclone Debbie last month.
(on camera):   Scientists say coral can recover from bleaching.  The problem is that  recovery can take more than a decade and this is the second 
straight year that we`re seeing bleaching on a mass scale on the Great Barrier Reef.

AZUZ:   Mr. Trash Wheel -- sounds like a kid`s toy.  And at first glance, it  kind of looks like one.  But though the name is trashy, its game is  clean.  
It uses the current of the Jones Falls River, plus  solar power, to catch garbage floating downstream and keep it out of the  Baltimore Harbor.  It 
puts the litter in a dumpster barge and  when that`s full, it switched out and towed away.  Mr. Trash Wheel  costs $720,000 to build.
Was that an offer officials couldn`t  refuse?  The money has gone to waste, so much has been thrown away, it`s  all being used for dirty work, though it 
didn`t come from a slush fund.  Mr. Trash Wheel makes cleaning up a de- breeze.  
And to all of you who`ve said my puns are trash -- well, there`s proof.
