Three days gone and theres no suspect. We look at the incredible response of china. A documentary on the air pollution. It got over 100 million views in less than 48 hours. See what you did there, lucy. One of the largest motor shows gets under way in geneva. Growth may be stalling in china, it is full speed ahead in europe and the United States. Stay tuned. Later in the show, live. We are going to find out what they are doing to take advantage of the changing trend. Its midday here in london 2 00 in israel and 7 00 a. M. In washington where the israeli Prime Minister, Benjamin Netanyahu, is due to give a speech to congress. Its put a strain on relations before a word has been said. Hes going to talk about his opposition. To make matters worse, Benjamin Netanyahu will be speaking to Congressional Republicans who did not inform the white house. From washington, we have the story. Thank you. Reporter Benjamin Netanyahu came to washington on a mission, he says to guarantee israels future. Hes getting an icy reception from the administration but counting on warm applause from congress, which invited him. At the annual conference of the proisrael lobby group, aipac, a warm up and effort to diffuse. My speech is not intended to show disrespect to president obama or the esteemed office he holds. I have Great Respect for both. [ applause ] reporter Previous White House meetings were tense enough without the high stakes of a nuclear deal hanging in the balance. There will be no sit down with the president this time. In an interview on monday president obama pushed back the rhetoric of the israeli leader. Prime minister Benjamin Netanyahu made lots of claims. This was going to be a terrible deal. Iran was going to get 50 billion worth of relief. Iran would not abide by that agreement. None of that has come true. Reporter dozens of democrats are boycotting the speech upset with the political maneuvering. It is not correct hes speaking for all jews. As a matter of fact, a majority of israelis think its a mistake for him to be here. I represent lots of people who are jews who are decidedly divided. The majority that i have heard from dont agree with it. Reporter mr. Netanyahu is undeterred. His lobbying mission in washington will happen here in this building in an address to congress. He hasnt said much yet, about the case he plans to make against a nuclear deal with iran. This is very much part of his strategy to try to undermine progress toward an agreement. And he will receive applause from those attending. Last time he spoke here he got 28 standing ovations. He will use those images again, to look strong at home ahead of the israeli elections. Global politics are also very local. Bbc news washington. Take you to jerusalem now. We have a Political Correspondent with the times of israel. Thank you for being with us on gmt. Relations between america and israel were already at an alltime low. Are israelis worried this will do long lasting damage to that relationship . I think that theres no question the netanyahuu. S. Relations are damaged from this. We have heard many times from democrats and others that the overall american israeli relationship goes far deeper than the Prime Minister deeper than any particular aspect of policy and its very old. Decades and more than that. I dont think israelis think they are going to lose the United States. It is a danger for netanyahu. As he gets up in front of Congress Later today and half of congress is empty, if many many more democrats decide to boycott, it will play badly for netanyahu. A calculated risk. You have elections around the corner. How is this playing out for him politically . Will it help him out, ultimately . Yeah. Those who like him say he has to take the iran issue you know to the world and be a responsible leader. Those who dont like him say hes grand standing. Largely, according to their political views from before this particular speech came up. I think its important to understand on the substance of his disagreement with president obama, theres walltowall agreement in israel. Netanyahu is doing something smart politically, internally, because hes keeping this issue, the iran issue, rather than the economy, hes keeping the iran issue on the front pages in israel. As you say, we are two weeks before an election. Given the risk of his appearance, you Mention Congress may only be half full. How embarrassing that would be. Given we dont know what hes going to say. What is it hes hoping to achieve . Thats one of the most interesting questions. Theres many many theories. One of the theories we are hearing from israeli officials is that theres a sense that look, if iran becomes a Nuclear Threshold state. If president bush is mistaken and miscalculating on this deal theres going to be a sense in the region the United States evacuated. The United States left countries like egypt, saudi Arabia Jordan and israel to fend themselves with a now nuclear rising iran. In that kind of situation, i think that theres an aspect to this that we havent really talked about, which is netanyahu hopes that israel can step into that breach israel can be that military patron if you will of arab states that want to resist iran. A regional counter weight. Netanyahu is not bothered by the clash with the white house because netanyahu actually needs a tension, you know the brazenness of this act of going to washington and defieing the american president builds israel as a Regional Power for that scenario where other regional countries see the United States as pulling back. Thanks for joining us from jerusalem. These warnings we are hearing from mr. Netanyahu about iran come as u. S. Secretary of state, john kerry try to reach an agreement. We are going to take you there and get the iran yan perspective from the persians that join us from there. Before we get to the substance of the talk how is it being viewed in iran . Reporter well in iran the iran yans are closely and anxiously following the negotiations. Most of them hope a deal is eventually done so the National Sanctions are removed and the economy starts moving. The iranians are under pressure. Judging by social media and reports out of the streets of tehran they are very very anxious about it. Not just them iranians here in the hotel behind me the negotiators are worried about what mr. Netanyahu might be saying this afternoon, what he has up his sleeve and whether he is about to share any details of the negotiations which could lead in derailing the negotiations. I should say, for the past few months i have been covering these talks and the negotiators have been keeping the details close to their chests. They have done a very good job. Seven dichbt countries discussing, they have done a good job. Now, those details would eventually be shared, but only after a deal is done not before. If before it gives a chance for opponents to derail the negotiations. Is there hope from president obama in the past 24 hours. He is not certain there will be a deal. Are they confident a deal can be reached . Reporter well of course the iranians know there are those who oppose the deal on both sides. Iran, the hard liners have done everything they could in order to get a better deal or not let it happen. The difference in iran the Supreme Leader has managed to keep everyone in line at least from the iranian side theres a voice. Of course they are worried about countries around iran. The arab countries, israel and those who are opposing the negotiations back in the United States. No one is certain, but, of course, everybody keeping their hopes high. Thanks for joining us with that. Going to take you live now to moscow.

Is this being broadcast live on television too . Well they had some short live introductions. Its not broadcast live. On the one hand state channels changed their schedule for respect of nemtsov and to show the fear of very shortly today. However, they underline that people who pay respects dont make political statements they emphasize the mourning the feeling of sadness and actually this is not the case. Many of the folks, allies and activists made statements today. Accused the state media and the kremlin of hatred toward the kremlin. We have heard nothing much from the police. Many people say its remarkable. What are the theories people are discussing as to why he might have been killed . Reporter in the absence of the real facts of different theories flourishing through the conspiracy allies of mr. Nemtsov think that this was a result of the progression toward the critics. Kremlin, however, investigators presented different versions stating one of them might be another one may be connected to business or may involve participation of the radical movement because of up to now, not much is known.

Troops are trying to retake the hometown of Saddam Hussein from Islamic State militants. We can see here the red line that is show where the militants have control or support. Tikrit, a crucial city on the main road 150 kilometers north of baghdad. It was taken by i. S. And allies last summer recapturing tikrit would move iraqs government closer to the goal of retaking the countrys second city mosul. It was home to 1,000 people last year. I know you have been speaking to one of the commanders involved in the operation. What does he tell you . He he is a Senior Commander in the main shia fighting along the iraqi army. They have been preparing for this Largest Military operation in tikrit for the past six months. Tikrit recapturing tikrit this central city of the heart of the province could be the fight and war against the socalled Islamic State group because it has joined borders where two strongholds for i. S. To the west, which is the largest providence and iraq its called the province. To the north i met one of the leaders in this shia alliance. I started the interview by asking him, how long would it take to end the operation in tikrit . Translator we are not in a rush to end the tikrit operation. We are very careful in our planning especially because the isis military plants explosive devices on the road the houses everything, even the lamp posts and cars. They are losing tactics in all the main roads leading to the city. The other key strategy is the use of snipers. Reporter the u. S. Led coalition doing enough to support you on the ground . Translator the 1990 war on iraq, the International Coalition was to carry out 1,000 air strikes a day, even in 2003 it was the same. Today, there is a fraction of this. The Coalition Must help the iraqi army in pinpointing the enemy. This will help control the isis controlled areas. It is not fair they are moving freely in vast areas of the desert. The impact of air strike is very minimal. Reporter so its not an easy battle at all. It is tough as the i. S. Militants are showing great and fierce resistance to the iraqi forces and the progovernment forces from the main alliance. They are using, basically, a manly warfare tactic. They are using booby trap cars and snipers. To recapture this important and strategic city they have to bear in mind all these dangers. Thats why the progress according to this senior military member in the alliance has been slowed a little bit since the start of the operation on monday. Thanks for joining us from baghdad. We have other news. Hundreds of parents in pakistan have been arrested for refusing to have their children vaccinated against polio. 471 mothers and fathers detained in the northwest province.

Pollution is a huge issue in china. They call for authorities to do something about it. What has been the reaction to the film . With me is our Chinese Service editor raymond lee. Theres a personal story behind it isnt there . They mention it at the beginning of the film. The whole idea of doing this was for concern for her infant child, which is obviously suffering a benign tumor. She worry about if its from the smoke or air pollution. Theres a poignant moment where a 6yearold girl asked if she ever saw the stars. She said no. Have you ever seen a blue sky . She said no. What else is so captivateing for people . Talking about her child. Actually what they are trying to go out. Then wonder what happened. We are seeing this little girl here talking to the journalist. What about the government . It is extraordinary they have let the fim be aired. In china, we all know without government blessing theres no way any documentary like this could be going out. So, you could say, although, the journalist claims the documentary was produced by herself, out of her own money. Certainly, government must critical of the government isnt it . Not as critical as we imagine. Certainly, the issue she raised was such an issue of critics of government. What is the government doing about pollution because we are used to seeing these pictures of Chinese People wearing masks. They say they are tackling it. Are measures being taken . Funny enough. Since the first of this year government introduced a new law on the issues. Unfortunately, i think that always the challenges are implementation. Theres recommendation and law. Thank you so much for joining us. Very quickly, before you go amazing reaction as well. Lots of people talking about it. Certainly. Generated a lot of comments. Very mixed.
