dire the situation has become. >> reporter: it looks like nothing out of the ordinary, a truck parked on the side of the road. but this is the scene of a crime. when police approached the vehicle, the driver was nowhere to be seen, they saw blood seeping out of the back. they were overwhelmed by a terrible smell. inside they found the decomposing bodies locked in. and suffocated. we don't know the country of origin, counting them is a slow gruesome task. >> translation: how many people were in the truck at this point in time i can't tell you, we fink it may be more than 20 people, 20 to 50 transported in the truck, and all the people have died. it's likely they are refugees, and highly likely they are

people trafficked from east to west. >> reporter: the summit in vienna was likely to be dominated by the refugee crisis, the latest tragedy drought an -- brought a grim urgency to these talks. >> translation: we are very much shaken by the news that up to 50 people lost their lives in a situation where criminals facilitated illegal border crossings did not care about them, even though they were on their way to places they thought would be safe. it admonishes the need to tackle the issue of migration and the spirit of solidarity, there are more refugees than ever since the second world war. the austrian and german chancellors want to move to a quota system, whereby european union countries commit to taking in certain numbers of refugees according to size and economic capability. such a system, says angela merkel, would be fair. certain e.u. countries such as

denmark and u.k. say they'll have nothing to do with european refugee quotas. the plan for quotas was first suggested by the european commission back in may. at this summit e.u. officials called for governments to have the courage to take difficult political decisions. >> these people come to europe, and come to europe to for protection. they need europe to protect them, and we need to live up to our standards of human rights and respect of international obligations to protect them. we need a european approach. everyone says so. >> the leaders also discussed ways of helping the boarder countries to cope and stay in the country of origin, that's a

acknowledged the assistance from washington. >> i don't always agree with the administration. it's a time to come together, put aside differences and celebrate the fact we had help from the federal government. the state and local government. the population is 20% less, damaging 70% of stock. thousands of homes are abandoned. part of the goal is to make sure that we recovered from the storm. and looking at the inebbing watties long before the storm happened planned parenthood told congress that controversial video discussing the sale of foetal matter was heavily

wednesday, it was announced that the man who headed the country's work safety regulator had been sacked. he was a former deputy mayor, a post held for 12 years, you sense that this investigation is going to be more open than previous similar inquiries. in the past they tended to be opaque. this time the authorities have been open with the information they are releasing. but we still do not know the answer to key questions. one, why is it that so many dangerous chemicals were stored less than 800m away from where people were living. chinese law states such kim calls have to be stored 1,000 metres away. most dead and injured were firme, were they trained to deal with a chemical disas er, why

how much recovery she has to do within the base and at large. >> if you look at the same poll, and when they ask democratic voters who they prefer, hillary clinton is ahead. on the other hand, her numbers are dropping, bernie sanders is up some, and joe biden is at 18%, despite the fact that he has not jumped in. >> we have to separate a you few facts. democratic women are holding. she still has 50% of report. bernie sanders is at 16%. that fire wall is keeper her well ahead in the primary, she's in a strong position, if the email scandal never occurred. there'll be a moving and mainstream candidate. bernie sanders is the moving candidate. and exists in the traditionful howard dean, gary heart and

bradley. with or without the scandal. hillary clinton would not have the problems. the problem for her is a general election problem. she can't say to the movement candidate "you are less electable, because bernie sanders and joe biden, who is not in the race are polling as well or better against the republicans. >> and she doesn't want to anger the folks. >> i find, and the poll confirms that the two candidates polling the best within their party have by far the highest negatives, donald trump extended his lead. >> that's a fascinating point. >> in some bays they are in for different reasons. hillary clinton has the highest negatives, because they are poor among independence and republicans. that said, 30% of her party don't trust her.

>> if you look and ask about the words people associate with hint, the top three were liar, dishonest and untrusts worthy. >> clearly it's impacted her. als i wrote last year, hillary clinton has been around longer than the internet. what she has going for her is the focus make history, the problem is what she has against her is the baggage. trump has his own baggage. a lot wouldn't vote for him at any point according to his things, and the words associated with him is arrogant blow-heart idiot. fine question - do you think biden will jump in, given the encouraging numbers? >> i don't. the reason is as encouraging as they are, i think ultimately hillary clinton, if he steps back and advisors remind him, is historically strong democratic nominee within the email

scandal. i think joe biden will say he had a place history, it's probably not going to improve. into we'll have interesting months ahead. >> thank you for having me. >> another big day on wall street, the major indesies were up 2% following rallies in asia and europe. oil futures surging up 1%, a barrel of crude surged. a major ruling is making is easier for fast food workers to unionize. for the first time workers will be entitled to bargain with corporate personalities such as mcdonald's. before they could only deal with the franchise where they work, which could lead to wage changes on a national level. >> protests called attention to the flight of fast food workers, leading to minimum wage increases. now a victory could help for a fight for higher pay.

the business models, a benefit of franchising and subcontracting is to spread the brand name while minimising legal risks and responsibilities. some of them are looking at doomsday scenarios. i think their predictions are very overheated. >> reporter: the new ruling may affect the upcoming case nlrb filed against mcdonald's and franchisees. the bottom line of the decision is that all that said, workers' rights are important. >> franchise owners are unhappy with the ruling, arguing they would not we able to run their own businesses if they had no control over pay and benefits. business groups called on congress to overturn the 3-2 ruling. >> socki salmon is pushed closer

1945. man made dangers were the concern. climate change is a big problem for the fish, making the water warmer, harder to survive. some believe the dams are making it harder. it extends the travel time from two weeks to six to eight. during the time they do biological things, going from a fresh water fish to a salt water fish, requiring energy. when you have to blow the energy ever the course of a couple of months, it takes a terrible toll. by the time they reach the fourth dam, their official numbers dwindled from 1,047 to 114 fish. a drop of 15%.

all the measures, and billions spent to allow the dams to stay, continue operating as they always have, has been to the peril of our fish. >> steve was head fish biologist for idaho fish and game, and spent 32 years to negotiate safe passage for salmon through the dams. >> you don't believe there's a way to have the healthy fish and dams. >> no, especially when you enter climate change into the picture. >> when the might tri seven ends, fewer than 100 fish are expected to make it. >> the river, that hosted life and death, could be entirely unlivable. finally tonight, the world's fastest man could not outrun a segue. usain bolt won the gold medal in a 200m race at the track and field world championship in
