A fifth day of protests ended with police using tear gas, rubber bullets and water cannon now on bbc news, in a few minutes against stone throwing youths itll be time for newswatch, who also set fire to but first, heres click. Makeshift barriacades. In contrast, during the day half a Million People held a peaceful demonstration in the spanish city. Theme music. Damian grammaticas sent this report from barcelona. Central barcelona. Parts of it are a battleground tonight. A full scale confrontation under way, between police and protesters. Over the years on click we have seen devices get smaller and smaller. Yet, with more storage and more round after round, fired by the riot officers. Processing capabilities. In return, stones, bottles and fireworks, hurled back at them. This is now the fifth this miniaturisation of devices night in a row of these has touched everything from our computers to phones clashes in barcelona, and whats clear is and even revolutionising that they are becoming worse and worse. More violent, more protesters on the streets and more response from the police as well, who tonight have used tear gas for the first time and rubber bullets as they are trying to protect the National Police headquarters which are just down here. The day began with huge columns of people, converging on barcelona from across catalonia. Some had been walking for three days to get here. A general strike had shut down the city. Now, they took over the streets. These are Pro Independence supporters, putting on a huge show of force after spain jailed on monday nine catalan leaders who tried to declare independence for the region two years ago. Its only going to stop once we achieve what we want, that are changes, real changes. Not all catala ns want the region to split away. Thereve been counterprotests by those who want to stay part of spain. They have been tiny by comparison. They dont speak for the majority, because the support for independence is not majoritarian. This was the spark for the violence today, protesters hurling eggs and cans at Spanish Police officers. Eventually, police patience snapped. Every day this week, there have been scenes like this. Police action, fuelling tempers on the street. The severity of the jail sentences for the catalan leaders has caused real anger. But so too have police tactics, which the protesters see as heavy handed. Spains Prime Minister has warned those involved in any violence will face the full force of the law. There has now been a week of unrest with no sign of it ending. And catalan leaders say their hopes of independence are undimmed. In just a matter of hours, borisjohnson will be asking mps across westminister to unite behind his brexit deal. And while parliament is deciding the fate of britains departure from the eu, thousands of protesters are expected to march through london demanding a new referendum. The stage is set for a Super Saturday but no one knows quite what the outcome will be. Its expected to be a knife edge vote in parliamen and, in the last few hours, a number of hardline tory brexiteers say they will back the agreement. Laura kuenssberg has the latest. Thats not the real borisjohnson. Its a fancy dress version, a climate protester who had scaled the scaffolding around big ben. The actual Prime Minister is teetering on an even narrower edge. He has to take a leap, not knowing if hell meet victory or defeat. Weve got a deal that allows us to get out of the backstop, thats abolished, and we can do free trade agreements as one whole United Kingdom around the world. Clearly, what matters is mps coming together across the house tomorrow to get this thing done. And ijust kind of invite everybody to imagine what it could be like tomorrow evening, if we have settled this. But in order to get this deal, though, you have given some concessions, youve accepted quite a significant Customs Border between Northern Ireland and the rest of the United Kingdom. That is something you said you would never do, you said no british Prime Minister could do that. No, on the contrary, nobody wants to have checks at the Northern Irish border. So, what weve agreed with the eu is that temporarily temporarily, and by consent of the people of Northern Ireland, if theres stuff that is coming from gb into ireland, or from anywhere else in the world via Northern Ireland into ireland, then, yes, there can be checks. But that, of course. And those checks can be levied by uk authorities. But that is very far from having a tariff border. By your admission, and its there in black and white in the deal, there will be extra customs checks, and for some people, including your allies, thats just not acceptable, that puts the union at risk. No, there are no tariffs going from gb to ni. But there are extra checks. They already are, as you know. But of course it is also going to be superseded, as we come out, as i hope we do at the end of this month, as we get on to negotiate the uk eu free trade agreement. The deal brokered by brains in whitehall and in brussels contains concessions from the eu and the uk. It leaves the future more open between the two sides, compared to the previous agreement, and in theory gives the uk more ability to trade round the rest of the world. But it does contain what could be significant changes to how Northern Ireland fits into the jigsaw of the rest of the uk, and thats not the only reason why the Prime Minister faces an uphill struggle to get this through mps. Lets get some of the days other news one of President Trumps most loyal supporters, the Senate Majority leader, mitch mcconnell, has condemned as a grave mistake the president s decision to withdraw troops from syria. Writing in the washignton post, senator mcconnell said it would embolden washingtons enemies and leave americans less safe. Afghan Officials Say an explosion during friday prayers at a mosque in the Eastern Province of nangarhar has killed at least 62 people and injured more than 30 others. Its not known who carried out the blast, which brought down the roof of the building. Its emerged that boeing employees exchanged messages about possible problems with the automated Safety System on its 737 max jet, nearly two years before the plane was involved in its first crash. The max planes have been grounded pending an investigation because of two accidents which killed more than 300 people.

Can borisjohnson get enough support from across the commons to see a deal finally approved . 0ur deputy political editor, john pienaar, has been crunching the numbers. For all todays sweet talking and arm twisting, this deal still leaves the future relationship up for negotiation. Brexiteers want to stricke new trade deals and break clear of new eu rules and regulations. Critics fear well be worse off. But first, Boris Johnson has to get mps behind his deal that allows the uk to leave. The numbers look painfully tight and he either has to win round the dup, which looks close to impossible, or look elsewhere for votes. Why . Well, in the commons, the pm needs 320 votes to guarantee a win. The dups ten mps dont want to be blamed for a no deal brexit but they fear customs and regulatory checks on goods arriving from the british mainland could weaken the union. They wont back the deal. Most of the pms 287 tories will back it, some reluctantly. A number of rebels have been won over. Some keen tory unionists may stick with the dup. Labour will vote strongly against the brexit plan. The government denies it butjeremy corbyn fears a tory brexit means weaker workers rights, poorer environmental safeguards, and nhs services, say, up for sale in a future trade deal. But some fear losing support unless brexit is delivered and a number will split or abstain and every vote could count. What about the independents who were thrown out the conservative party . Well, they will split too. Some will back the pm, including a few who want back into the tory fold, they want to keep their seats. Others want to stay close to the eu but they might swallow this deal in the meantime. A few who are worried about britains future after brexit may refuse. Mrjohnson can forget jo swinsons lib dems and the snp and some others, they are against brexit. There are more struggles in the pipeline, a push for another referendum, for example, and some mps will vote to guarantee a brexit extension, they will try to make sure the deal comes before they approve it and that there is no last minute attempt to back out. The governor of the bank of england, mark carney, has welcomed the progress made by the government on brexit. But he said that borisjohnsons current deal would hit the size of the uk economy more than the closest version negotiated by theresa may. 0ur economics editor, faisal islam, reports from the International Monetary fund meeting in washington. In washington, meeting the financial leaders at the imf, the bank of England Governor Mark carney says that the deal back home is a big economic positive, taking a disorderly brexit off the table. I can be absolutely clear, relative to no deal, this is materially better. Its very welcome news. Its welcome in the uk, its welcome globally. Literally globally, i heard that last night, bilaterally, in the bigger room at the g20. But thats compared to no deal. This new deal could itself lead to the return of certain customs checks, not currently required between the uk and mainland europe. Many independent economists and former chancellor Philip Hammond calculate the more distant relationship signalled by borisjohnsons deal would lead to a smaller economy. If there are extra frictions in the uk, or gb eu trade, that will mean the economy being smaller, or growing by less . We dont know exactly what would have been negotiated under Prime Minister mays deal in the end. We dont know if this deal is adopted, exactly what would be negotiated under this deal in the end. I can tell you that myjudgement would be that there is some overlap between the two. Now, if it were the deepest possible partnership under Prime Minister mays deal, there wouldnt be overlap between the two. And that last bit was diplomacy. Thats understandable. Diplomacy at a delicate moment. But the basic message from the governor here in washington is, yes, the chances of a disorderly brexit are lifting, and that is a boost, but a fundamentally more distant relationship between the uk and the eu will also have consequences for the british economy. All this comes at a time when central bankers like him are running out of firepower and there is more scope for governments to boost a precarious World Economy by borrowing more. We are in a world that has challenges, it is likely to have very low Interest Rates for a while longer yet. That creates greater opportunity for fiscal policy. It also creates opportunities for private businesses who want to take advantage, if they see where the world is going, if they see an opportunity, to borrow and invest, and growjobs. Economic turbulence in the world stretches well beyond brexit. The boost from lifting the no deal cloud is real. But its tempered by a new uncertainty about where exactly brexit is heading. Faisal islam, bbc news, in washington. Thereve been a Record Number of arrests across the uk this week, after a crackdown on so called county lines gangs thats organised criminals who supply drugs. More than 700 people have been arrested, and police have seized more than 400,000 pounds worth of drugs, and over 150 weapons, including guns. The gangs sell drugs from cities to towns often miles away, and often use children to deliver them. Our home affairs correspondent, tom symonds, joined police in birmingham and worcester. Aston, birmingham. Police have flooded the area looking for the signs of county lines dealing drugs, money. Lloking for cars previously identified as involved. Looking for cars previously identified as involved. There is intelligence on the vehicle linking to drug dealing in the local area. Suddenly, up ahead, a pursuit begins. When they find the suspects car, its crashed into a gas main. Turn around, go the other way. We can hear it. The gas escaping. They have to clear the street, but what about the suspect . Hes run out of the vehicle into that premises and slammed the door. Cue a helpful firefighter. Go, go, go but the suspect has disappeared. By his actions, weve had to evacuate the entire street, in the rain, small babies, mothers, the elderly. But the harm goes further. The dealers have created supply networks on rail and road and theyve recruited vulnerable young people to carry the drugs. Its called a county line not because of trains but because urban dealers set up mobile phone lines to sell drugs in rural areas like worcestershire. Its the county bit of county lines, its where the drugs are being taken and the police have told us that one drug dealer is making £4,000 a day selling cocaine down there. West Mercia Police make a move against suspected dealers being tracked by Neighbouring West Midlands Police from birmingham. Rural and urban forces working together. For the drugs gangs, county lines gives them a bigger market across the country. For the police, it means they have to co ordinate their efforts, forces talking to forces, different types of units, uniformed and plain clothes, using technology, all has to work together. It means a big operation like this. We know more than we have ever known about the gangs and those people that get exploited, as part of county lines activity, because we have real close Co Ordination now between different forces up and down the country. But there will be more of these co ordinated operations. Bang. Because they get results. 169 weapons were found in this one week, including these. The county lines gangs deal in drugs and violence. And they seem to be here to stay. Tom symonds, bbc news. This is bbc news, the headlines protestors have clashed with police in barcelona, after a huge demonstration by catalans against jail sentences imposed on separatist leaders. Super saturday in the British Parliament just hours before mps decide in a special sitting whether or not to back borisjohnsons brexit deal. The first all women space walk has taken place, in another milestone for Space Exploration. The american astronauts Christina Koch and jessica meir replaced faulty equipment on the outside of the International Space station. More than 200 people have carried out spacewalks since 1965 but only 14 of them were women and until today they were always accompanied by men. Gareth barlow has the details. For almost eight hours, they made history. The first all women spacewalk in history. Christina koch, and jessica meir stepping outside the International Space station, 400 kilometres above the earth. We hope we can provide an inspiration to everybody, not only women, but to everybody who has dreams and is willing to work hard to make the dream come true. Watching from solid ground as they made repairs to the space station, President Trump hailed the moment. And i just want to congratulate you, what you do is incredible. And so, youre very brave people. I dont think i want to do that, i want to tell you, but you are amazing people. Earlier, what would have been the worlds first all womens spacewalk was cancelled because nasa did not have enough medium sized spacesuits. In the early days of human space flight, women were not astronaut. There were only a couple selected as russian cosmonauts. It took nasa until 1978 to start selecting women. Proving that there is space for us all. Gareth barlow, bbc news. Dr carly howett is assistant director in the department of space studies at the South West Research Institute in boulder, colorado. She told us why this space walk is a cause for celebration. Fundamentally these are professionals doing the work they have been trained to do and so they were the right people at the right time to do the job and they did it amazingly well. It is a difficultjob and they have been training for six years to do it. Above all they are professionals. But this is a significant moment and i dont want to take away from that at all. This is the first time that two women have done a spacewalk together and does your report already said, women have done spacewalk the first was in 1983. This is the first time that two women have done it and i think that is a significant milestone in terms of Space Exploration for women and all minorities. About 600 people have gone into space and only 65 women are among them. Why are women onlyjust beginning to catch up . Well, i think it was to do with opportunity. When Space Exploration began, most of the people who flew had heritage in the air force it traditionally test pilots and traditionally men. It has been changing slowly. And as we go forward, women will continue to play an important and perhaps a dominant role in a struggle. Space travel. If you think about even the language that we use, manned space flight is still used very widely and it has that heritage. But as we move towards the future, these events and the coverage you give them show that women have been involved a
