this is al jazeera america live from new york city, i'm randall pinkston. at least 20 and as many as 50 refugees were discovered dead today in a truck in austria. that truck found on a main road close to the border with hungary. austria's chancellor has hold european leaders the continent must fight human trafficking and give asylum to refugees. they are meeting right now as thousands of migrants try to make their way to the european union. barnaby phillips has more. >> reporter: we have heard from western balkan leaders that they need more help from wealthier countries in the e.u. from germany and austria. and what we have heard from austrian and german leaders that the european union has a whole has to step up to the challenge, that it has to share the responsibility, fairly equally

amongst the entire block. that if european solidarity means anything, it would mean some form of quota system across the e.u., relative to country's wealth and capacity to take in refugees. this is something that has faced very stiff opposition from the united kingdom in particular. the danger was if europe does not act as went, well, then conventions like the dublin convention start to lose all meaning, and you get a series of ad hoc responses. and the most graphic is that being imposed by the hungarian government at the moment, building a razor wire fence to keep people out. >> that's barnaby phillips reporting from vienna. so far more than 4 million syrian refugees have fled to neighboring countries. turkey has the lion's share.

nearly 2 million syrians live there. more than a million have gone to lebanon. jordan has more than 600,000. and a quarter million are in iraq. another 130,000 in egypt. the spokesperson for the united nations human rights campaign in washington, d.c. says the scale of the refugee crisis is bigger than anything the world has seen in decades. >> war conflict and persecution have now caused around 60 million people to flee their countries. that's approximately the population of the entire united kingdom. this is the largest number of people fleeing war since world war ii. it's a global crisis, and certainly it's driven by syria. syria is the major factor, with over 4 million refugees. inside syria we have over 7.6 million displaced within the country itself. so it's -- it's -- unfortunately we are first respondering, b

but -- the ultimate solution must be a political one. the u.s. is the largest humanitarian donor, over $4 billion from the u.s. the european union as well, as have other countries. but in terms of reis the lment, resettlement is only a small part of the operation. the hope for a solution that s that syrians would veb yulely return to their homes, but unfortunately as you mentioned the syria conflict, now into its fifth year there seems no end in site. we're very grateful to the u.s.'s commit. it has an open ended commitment to resettle syrians as part of its over 70,000 vettelment every year. the u.s. vettels more refugees than any other country. so certainly the u.s. is extremely generous, and other countries are extremely again

royce, but yes, we see the numbers increasing in the years ahead. >> the says it can take anywhere from 12 to 18 months for refugees to be resettled in the u.s. two tv reporters in virginia were shot as killed during an interview. john terrett reports. >> reporter: some call it a suicide note others a manifesto, it was delivered by fax to the headquarters of abc news roughly two hours after the shooting. in the 23-page document, 41 year vester lee flanagan talks about being a human powder keg, angrily motivated. he said he was inspired by the columbine shootings, and the virginia tech shootings. and he talks about being bullied and discriminated against

movie theater. >> we do know one thing, he is going to die in prison, and for us, that's good enough. >> reporter: more than 70 people were injured in the shooting rampage, adding many years to holm's 12 consecutive life sentences. during the sentencing the judge told holmes he had a hatred for man kind. his attorneys say he will not appeal. joe biden may be joining the race for president. for the first time he is admitting publicly that he is considering a run. but in a conference call, he said he is not sure if he has the, quote, emotional fuel to get through campaign season. biden lost his son bo to brain cancer back in may. donald trump and his g.o.p. rivals have proposed building a huge wall between the u.s. and

mexico. but just how effective would a wall really be in paul beban has been doing some fact checking along the border. >> reporter: this is the u.s. side of the border fence. you can see it is built of steel and concrete. it looks like it would be impossible to get over or through. but people do. they manage to get across this border one way or another. they climb over or tunnel under. last year when i was here filming my crew and i saw two young men climb over this defense and back in no time at all. we assume they were drug runners. take a look. wow. they just shot right over it. donald trump says he'll stop young men like those and anybody else trying to cross this border illegally but replacing this fence with a wall. he then said he would call it the great wall of trump.

and then he said the name may be a joke, but he is serious about building the wall. so let's take him seriously. is building a wall the entire length of the u.s., mexico border almost 2,000 miles even possible? let's take a look at the facts and the fence. so we're driving along the border to the east now. the fence is just scrolling by there mile after mile. during the 1990s, and especially since 9/11, the u.s. spent billions to massively beef up border security, and as far as stopping illegal crossings or terrorists, it's not clear what it has gotten us. along the border there are about 670 miles of border fence in sections, about a third of the border. and depending on the terrain and

type offense it costs anywhere between 200,000 and $15 million per mile to build the fence. so the total bill, about $2.4 billion. trump says his wall would be bigger and even more secure than the current fence, so it's safe to say it would cost many times what has already been spent. that $2.4 billion was just to build the fence. it costs hundreds of millions of dollars more every year to maintain it, then there's the $3.7 billion we spend on 21,000 border patrol agents. so the reason that border patrol agent is parked up on that hill, he is probably there 24/7 this time of year, because this is a riverbed. it's a monsoon season here, and that means very heavy thunderstorms, huge volumes of water coming through a place like this. so they have built the fence with flood gates that they keep

open to let it through, and all they have is two little strands of barbed wire. so obviously very easy to come over, but impossible to build a wall in a spot like in. and the border patrol says you don't actually need a solid wall, because there is where the ruggedness and the remoteness of the terrain does the job for you. but experts say maybe the strongest argument against a wall is that a wall would not address the biggest part of the illegal immigration problem, and that's because the majority of people who make it into the country illegally do it right through ports of entry. they hide in vehicles or use forged immigration documents. so could trump even build his wall? well, that certainly isn't clear. would it help solve the problem? probably not. the one thing we know for sure is it would cost an extraordinary amount of taxpayer

money. paul beban, al jazeera. it's an ad campaign causing outrage in a detroit suburb, the flyers about an up coming election, many are calling racist.

says iran may have expanded one of its military sites while nuclear negotiations with the u.s. were underway. the confidential leaked report says the agency has observed probable construction on a major military complex outside of tehran. stephanie sy spoke with congressman alan grayson. >> i don't think the deal will bring about the peace we were hoping to see. it does nothing to address terrorism support by iran for militant groups around the area, involvement in iran in what amounts to the shia sunni war -- >> but this deal was supposed to constrain iran's ability to get a nuclear weapon. do you believe it does that? >> well, that's the problem, i have been saying for years we needed a broader piece, and all it does is moth ball for a

period of time the iranian nuclear program. it doesn't bring peace in the region, and it should have. >> graceson who is a democrat says he has not decided wh he will suppose or oppose the deal with iran. the hunt is on for whoever is putting up racist fliers in a suburb. as bisi onile-ere reports, some in the community believe an outsider is behind the flap over the fliers. >> reporter: the headline is bold, let's get the blacks out of southfield in november. with a message, let's take back our city printed at the bottom. on one the images of two white deputy police chiefs and three other white men running in the upcoming election. the fliers began surfacing over the weekend. on another flier is a photo of

>> my response is of course that i'm not. and i believe this is someone who is either trying to incite racial tension in our city, which we -- we lack, and/or it's dirty campaign trick. >> no matter what the motivation is, this is absolutely despicable, and we will not tolerate it in our community. >> reporter: pat is president of the mlk junior task force. she questions the motive behind the flyers. >> it may very well be that this was not done by a racist individual or organization, but in fact done in order to incite people of color to come out to the polls and vote directly opposite of what the flier purports. >> reporter: many who live here suspect the person behind the fliers didn't a southfield
