croatian borders refugees have spent hours under the hot sun with little food or water. they have been patient, waiting to board trains to registration centers, but their numbers are building. children are passed out from the crash over the heads of riot police, separated from their parents. [ screaming ] >> reporter: this was meant to be their safe route to the european union after the riots at the hungarian border, but croatia wasn't prepared for these numbers. buses from hungary are off loading refugees a few hundred meters from the border. in the last 24 hours thousands have made this journey, croatia now says it won't take anymore. those that made it through, wait to be transported to reception centers near the capitol. centers that lie loesz than 100

kilometers from croatia's border from slow -- slovenia. slovenia, says it will create a safe zone for them to pass through. >> translator: we have to protect the border. slovenia is found by the rules we will honor fully. that is our obligation. >> reporter: the refugees will be divided into three groups, those who want to stay, thoegs who don't, and those who belong in a special vulnerable category. back on the border with hungary all of those left look vulnerable. they have chosen not to leave, risking the elements and further violence. >> i will stay here to open this door. i will not go to croatia and take my finger and slovenia and after that i will stay in slovenia without work, without

anything. sorry not go. >> reporter: they are determined the gates will eventually open, the barbed wire removed and they will be free to move on towards the e.u. al jazeera's lawrence lee is across the border with croatia. he is with us now live. lawrence that is where some of the refugees are arriving and trying to cross over into croatia, isn't it? >> reporter: yes, that's exactly right. and i think what you can see happened today is the results of the bottleneck that was created by the actions of the hungarian government who obviously treated the refugees with a mixture of violence and contempt for all of that time. as soon as the croatian government said you can come this way instead come to our border and go in and out the other side, then they have just come by the thousands. i don't know if you can see the buses at the end of the road.

we have seen a half a dozen or more in the past couple of hours. all of them have had 50, 60 people in them. they are dropped here just on the serbian side of the border. they walk up this dirt track here and then take a sharp left and go this way, and we followed them earlier on two kilometers down that track is croatia. we followed them there. it's the most remarkably undane border. it is only a marked by a couple of stones. we spoke to some of them and they said where are we now? we said you are in the european union now, and they are supposed to have something in place. but clearly as charlie said in that report, the facts of this bottleneck having been released by the serbians who bussed everybody up here, and the croatian has caught the croatian unaware. they don't know what to do with the numbers, because slovenia has said it is imposing new

border controls as well. so at the moment the door is open and everyone is rushing through, but the door might shut again if croatia says it can't deal with the numbers. >> yeah, croatia caught unaware as you say. many of these refugees are camped at the nearest railway station from what we have seen. >> reporter: yeah, that's right. there's a town which is just to the other side there. there are police there and some local volunteers handing out biscuits and bottles of water. and the idea i suppose was to be continue to journey further north, but it doesn't look that croatia quite knows how to deal with the numbers. and it has lead to this extrordanaire and acrimonious relation between these countries. croatia and serbia have seemed

to almost be acting in tandem to get people through, contrast to the hungarian attitude which is keep them all out, but that has lead to a complete rauch between serbia and croatia and hungary on the other. but if they are now stuck in croatia, what is going to happen to them there if slovenia has shut its border and won't let them through, and that's why slovenia and austria are calling for yet more sergemy european union talks. so it's painfully slow for these refugees. they get stuck again, and then make another break, and then they get stuck again. it is frankly from the european union's point of view, it is a complete shambles. >> thank you. hundreds of reges are at austria's border with germany wait drogsz.

trains connecting the two countries have stopped running. the refugees including many families are stuck on a bridge waiting to be let into germany on foot. with more european countries inte rer do you see border checks thousands continue to land each day on the beaches of greek islands, and as jonah hull reports they are prepared to risk everything for a better future in europe. >> reporter: anyone who thinks that the closure of european borders will deter this human wave would be wrong. as we watched on the shores of lesvos, the boats came in. you have heard that there are problems. but will this stop you? >> i will not stop. i will -- i will be -- >> reporter: you'll keep going.

>> yeah, i'll keep going and arrive to germany to achieve my ambition. >> reporter: carefully wrapped in makeshift water proofing, smartphones are vital tools serving as road map and guide. photographs and video on social media feed their expectations. this is a smuggler's facebook page, happy faces on calm seas, safe for all ages at around a thousand dollars a head. there is even a fancy yacht for higher, but that costs much more. the promise is clear, get your tickets here to a new life in europe. the reality is different. cheap, overcrowded boats, accident bound. sometimes the people aboard only learn how dangerous this journey can be, when it's too late. this man and his baby survived but in recent days close to a hundred lives have been lost in greek waters many children.

here comes another boat. now volunteers guiding them in. local greeks ready to pounce and steal the engine. no matter what triggered this mass movement of people the war in syria or germany's implied promise to take them all in, or the false promises of the people smugglers, no matter what started it, no matter what perpetuated it, there's no easy way of stopping it. >> translator: we go know that the border situation is difficult, but god willing things will get better. may god show us the way. >> reporter: whatever calamities may lie ahead as europe's borders open and shut, whatever tragedies have yet to unfold in these waters, as long as there is war, and poverty and as long as there are smugglers getting rich on the opposite shore, they will keep coming. ♪
