Plus im lucia newman in havana, where president barack obama historic visit is raising hopes but also concerns about the future in communist cuba. Turkey and the e. U. Have clenched a new deal to try to stop the flow of refugees and migrants to europe. In turn ankara will receive political and financial rewards. Under the controversial agreement, all migrants arriving illegally to greece from turkey will be returned. And for every syrian who is returned one syrian currently in turkey will be resettled in the European Union. And turkey will receive 6. 7 billion. The e. U. Is also aiming to grant turkish citizens visafree travel in the schengen by the end of june. Neave barker has been following events in brussels. So a lot to cover there, but crucially, what happens next . Reporter well, we are receiving more and more confirmation from e. U. Leaders from the 28e. U. Leaders that have been gathered here for the last two days, information coming in from the fins, the czechs, and now t the lithuanian Prime Minister. We are expected to hear from the turkish Prime Minister himself. He will add his final seal of approval, although we gather after three meetings this morning that the terms of the agreement have now been accepted. We gather that they will apply from sunday at midnight. This means that between that time, going into the early hours of monday morning, any refugees arriving in the greek islands or elsewhere in the e. U. Territory would be subject to processing, and then returned back to turkey. It may be sometime yet, though, before we have a full understanding of the scale of the returning numbers although the e. U. Have suggested somewhere between 72,000 to 73,000 may already be eligible, these people who are actually based in turkish camp, may already be eligible to be resettled here in the European Union. We are reaching a critical moment, that allimportant press conference, where the Turkish Foreign minister will add his seal of approval. Since the start of the crisis, they have been trying to deter people from making the journey. I guess thats behind this deal that they have with turkey that they will send people back. But its a very cointreau ver shall deal as well with some Rights Groups claiming it may not be legal. It has been incredibly controversial, which is why it has taken so long to initially come up with a deal to put in front of the turks, and now, of course, to come up with a deal that turkey would be happy with as well. But the draft was first produced on march 7th. It has been worked and reworked, the European UnionCouncil President has been traveling around europe trying to drum up support. And there are sticking points the payment to turkey, and the request of easing of visa restrictions, allowing turkish nationals to travel in the schengen area. We are now pushing towards a conclusion in this lengthy process. The question is now, what happens next when it comes to the practicalities of all of this. When it comes to setting up processing centers, and funding the movement of essentially stateless people from the e. U. Back to turkey. All of these things will need to be discussed, but in the next 30 or 40 minutes, were looking at the conclusion of a lengthy and diplomatic process. Neave barker thank you. The deal in brussels is going to add to the fears and frustrations of syrians looking for safety and security in europe. Other people in turkey, though, see opportunities from southeastern turkey here is lawrence lee. Reporter the bizarre here was a trading post on the silk route in the 16th century. Still today the smells and sites will be familiar for people who have travelled through central asia or north africa. Its a mixture of kurds, turks and arabs. The deal between the e. U. And turkey would allow them all visafree travel through europe. Many you speak to here have no idea about the deal. But some who do say if europe wants to let them in without a visa, why not see more of the world. Why not . Anybody ask if they have opportunity and some money they can go for holiday, and they dont have to pay 400 lira, and they wont [ inaudible ] embassy or english embassy, wait for visa, this is very difficult thing. Reporter but the deal has been heavily criticized over allegation the e. U. Is so intent on keeping refugees out, it has caved in to every turkish demand. It all comes at the very time turkey is accused of growing authoritarianism. So fortress europe could become fortress turkey. Many human Rights Groups say sending refugees back here could break international law. The whole reason so many refugees make the dangerous trip to europe is because staying in turkey means it is difficult to get their children educated and to get a work visa. Yet in return every single turkish citizen would enjoy far greater freedom of movement. So Syrian Refugees like these find themselves stuck in the middle of an extroerd neir set of segment noeshation. The response has become ankaras most powerful bargaining chip and it appears many refugees know it. They feel cornered, let down, their rights not respected, and maybe betrayed. Reporter the fact that the e. U. Is even prepared to talk about this, demonstrates just how far it will go to stop the flow of refugees. Lawrence lee, al jazeera, southern turkey.

They hope the courts will force the government to prodouse a new plan to clean up britains air. Something like 40,000 people are dying each year in the u. K. Because of air quality. We want the government to take responsibility so people are not dying. Reporter londons air looks cleaner than that of many cities in the developing world, but nitrogen dioxide is an invisible killer. Its the elderly and very young who are the most vulnerable. This is a worried london mother. The governments own statistics show that in london, pollution levels will not come down to acceptable levels until 2025. So thats ten years away. My eldest son will be 18, middle son will be 16, and my youngest will be 12. So they will have done most of their growing, the damage to their lungs will be done. I cycle across london every day on my way to work on very busy streets. I wanted to know how much damage this journey might be doing to my lungs. We have been measuring air pollution in Central London along my daily commute, using this machine. And it has just told us that the amount of nitrogen dioxide here is almost five times the safe level according to e. U. Regulations. Now obviously this is not entirely scientific. Ideally we would look at an average over weeks or months, but it does suggest that the air im breathing in Central London is not safe.

Speaking of that story we just brought to you from belg m belgium, we can speak to natasha who is in brussels. Tell us about the suspect. Reporter what were seeing at the moment is another raid. Hahhing i say another because there was one earlier this week. There is a raid by Belgian Police going on in the belgium capitol. There has been several shots over a period of time. Belgian media are reporting that one person has been wounded and possibly killed, and we would be looking at a situation in which one of the suspects in the november 13th paris attacks could be amongst those people loved this afternoon. And remind us of the connection between the attacks in paris and that specific neighborhood mollenbeck where this raid is going on, the second this week. Thats right. Once again the attacks in paris on november 13th in which 130 people were shot dead by a group of attackers in in the music conference haul next to the stadium, and also cafe terraces across the city, those attacks on november 13th, which really shocked france as the investigation continued after that, to find out who those attackers were, the link to belgium and this neighborhood was uncovered. Many of the attackers came from this area, grow up in the area, or were spending time in this area. We have seen police carrying out a huge antiterror operation in the area. In that raid they said was linked to the paris attacks on november 13th. One suspect was killed in those raids whilst two were on the run. Now whether or not those suspects are the people involved this afternoon remains to be seen. Obviously there have criticisms of french and Belgium Police for letting the suspect escape from paris. If this story is true and we are all checking it it could potentially be a huge coup for both police forces. It would be, but some may say why did it take so long. He was one of the attackers who shot people dead on cafe terraces actually he had a suspect belt and exploded himself. His brother his brother escaped from paris, managed to free across the boarder into belgium and many people have said why are the authorities unable to track this mostwanted suspect, and if it is him now, then, of course questions will be asked of why he was not caught sooner.
