The numbers headline the days developments in the London Bridge attack that killed seven people saturday night. Malcolm brabant is in london, and filed this report. Reporter police were in action in east london again this morning, raiding an apartment complex and a tire shop, detaining more people in the wake of saturdays attack. We have hundreds and hundreds of officers engaged in trying to piece together whether anybody else knew about the attack or planned or supported it in any way at all. Reporter the three attackers were shot dead saturday night, minutes after they drove a van into people on London Bridge, and went on a stabbing spree. Today, officials named two of them 27yearold Khuram Shazad butt was a british citizen born in pakistan. Rachid redouane claimed both libyan and moroccan nationality. Butt was known to the authorities as an extremist. Last night the Islamic State group claimed responsibility for the attack. Meanwhile, campaigning for britains thursday general election resumed today. Labour Party Leader Jeremy Corbyn called for conservative Prime Minister theresa may to resign. May fired back, in an interview. Weve given increased powers to the police to be able to deal with terrorists. Powers which Jeremy Corbyn has boasted he has always opposed. Reporter london mayor sadiq khan, also a labor party figure, criticized may for downsizing Police Forces when she was home secretary. We have had to close police stations, sell Police Buildings and weve lost thousands of police staff. Reporter khan himself drew criticism from across the atlantic. Yesterday, the mayor told londoners theres no reason to be alarmed by the increased Police Presence in the city. President trump then fired off a tweet that said at least 7 dead and 48 wounded in terror attack and mayor of london says there is no reason to be alarmed theres history here khan criticized candidate trump last year for his proposed travel ban, and the candidate challenged him to an i. Q. Test. The mayor did not respond to sundays tweet, but many argued the president took him out of context. Mr. Trump followed up this morning, saying pathetic excuse by london mayor sadiq khan who had to think fast on his no reason to be alarmed statement. Main stream media is working hard to sell it a white house spokeswoman followed up there is a reason to be alarmed. We have constant attacks going on not just there but across the globe and we have to start putting National Security and Global Security at an all time high. Reporter forensics officers carefully searched for evidence again today, but some semblance of normalcy returned. Pedestrians and cars were allowed across London Bridge. But around three of the citys iconic bridges, the stepped up security was unmistakable. On westminster bridge, where tourists line up to take pictures of parliament and big ben, overnight, they installed steel barriers between the road and the sidewalk. There was resistance to the move, but officials moved quickly to get the protection in place. At lambeth bridge, next to westminster, its still a work in progress, as theres only one barrier in place on the north bound side. At least one former high ranking security official said islamic extremists should be placed in internment camps. But maajid nawaz, a leading anti radicalization expert warns against them. Internment is a prepestrous suggestion. And in fact will only make the problem worse. If we recognize this is a jihadist insurgency then we have to recognize that we have to succeed in being able to isolate the jihadist insurgents from the communities they seek to recruit. Reporter and moderate muslim spokesman mustafa field also believes in Community Based deradicalization programs. Its these low level cowardly attacks that are now seeping through. There is nothing sophisticated about what they are doing. We need to make sure that our polities Bring Community together and that we Work Together to confront this evil ideology. Reporter this evening the city of london held a vigil to honor the People Killed in the attack. This vigil which has been designed to send a message of solidarity and love from londoners is breaking up right thereve been about 5,000 people here. Theres been a minute of silence. And the atmosphere right now appears to be calm and relaxed. But nevertheless the police are on high alert and right behind me theres a man being frisked. For now, the threat level in britain remains at severe. That means an attack is still highly likely. For the pbs newshour, im Malcolm Brabant in london. Woodruff in the days other news, saudi arabia and other arab states cut all ties with qatar, sending the Persian Gulf Region into a new crisis.

On the ground in venezuela with an economy in freefall. Our politics monday duo on the president s travel ban, and much more. Woodruff for more than 35 years, the socalled gulf cooperation council, or g. C. C. Has united kuwait, saudi arabia, bahrain, qatar, the United Arab Emirates and oman. The goal to put the wealthy, predominantlysunni nations of the persian gulf behind common cultural, political and military objectives. But overnight, longsimmering tensions between qatar and several of its fellow members, and other regional states, burst into fullfledged diplomatic crisis. Saudi arabia, bahrain, the u. A. E. And egypt, among others, broke off diplomatic contact and suspended commercial ties with the qatari government. For more on these dramatic developments im joined by joyce karam, the Washington Bureau chief of alhayat, an International Arabic daily newspaper. Joyce, thank you very much for being with us. Why did this happen . Well, as you said, judy, this is a very dramatic escalation. We have been covering tense relations between qatar and saudi arabia and the u. A. E. For a while, but its never gotten to the point where theyre not only closing embassies, sealing off the border, blocking airspace and maritime access to qatar. Qatar, as you know, is a country smaller than the state of connecticut. Its a completely dependent for its Food Supplies for 40 of its food splice come from saudi arabia. So this is dramatic, unprecedented escalation. It comes at a time wit when we e told both the saudis and the emirateys have had enough. Almost every alignment in the region, there are two camps today, if you want to say. Theres the pro Islamist Movement camps where qatar is now boxed in, and the more closer to this administration, the saudi and the emirate and the egyptian camp, and this is where things are going from here. Woodruff were hearing these five countries are saying qatar is too extremist, that its been sponsoring terrorism. The cathe qataris say thats no. Whats really going on . This asliement in the region was arab spring in 2011. Qatar today is seen leaders from hamas, taliban and will be host ago wellknown extremist in the region for an islamic cleric. So, in that sense, qatar is seen as scrr closed, has boxed itself in with these Islamist Movements and this has been a problem with its relations with egypt, with saudi arabia and with the emirates, and is perceived as a clash within the g. C. C. Whether forward or counterterrorism or other. Woodruff we know the countries ac suing qatar have themselves at times supported some of the extremist Opposition Forces in syria, for example, so is it so clear that qatar is doing Something Different from what these other countries have been doing. I think syria is a very complicated battleground, but if you look at syria itself, the main group is affiliated with al quaida and is supported by qatar. Its the head of a group that gives interviews on aljazeera that qatar might have indirectly paid a ransom of 1 billion that went to extremists on and in surria. So this has become problematic within the g. C. C. They do feel bolstered after the trump visit to do more on that front. Woodruff because its true this happened just a week or two after President Trump was there insaudi arabia. But lets quickly talk, joyce, about how this affects the region and relations with the u. S. Going forward. This is a very tense time in the region. This is an almost arab cold war happening within the gulf cooperation council. I think the u. S. Tried to distance itself today. The pentagon related hits defense relations with qatar, an air bass thats active, a counterterrorist will be not pim acted by this. The kuwaitis are trying to mediate and find a Common Ground in the coming hours. If they can achieve a breakthrough, you know, given the list of demands that saudi arabia and the u. A. E. Have put together, maybe that means the citizens of qatar will not be expelled from this country. Woodruff is there fear this could lead to allout war . I dont think any side at this point is in order a military confrontation and i think qatar, given its a small country, and most of qatars strategic depth is within the gulf region, i dont think qatar has an alternative but to fix this with its neighbors. A saudi official tells me the only way there would be an exit is if qatar went away and, you know, forgot its old habits. So were looking theyre looking at a change of behavior from qatar, not just demands as it happened in 2014. Woodruff joyce karam, tough subject. Very tough subject. We appreciate it, with al hayat. Thank you so much. Wooduff after years of recession, skyrocketing inflation, and hardship, the oilrich country of venezuela is spiraling into social and economic collapse. Many of its people have been taking to the streets, on an almost daily basis for the last two months, to demand that president Nicolas Maduro step down. With the support of the Pulitzer Center for crisis reporting, special correspondent nadja drost and videographer Bruno Federico went to caracas to find out how the wave of uprisings is creating a political crisis. Reporter venezuela today an economy in freefall. Tripledigit inflation. Dire shortages of nearly everything, from food to medicine. The social and economic crisis that started intensifying after president Nicolas Maduro took over from his iconic predecessor hugo chavez is tailspinning into a political one, as Anti Government protests rock the capital, caracas. Chavismo, the populist form of socialism branded by chavez that provided services for the poor paid for by profits from the Worlds Largest oil reserves, is teetering on the verge of collapse. Behind us is a sea of angry venezuelans who have been taking to the streets since early april, protesting the government and its handling of this countrys deepening crisis. But now that president maduro is pushing ahead with his controversial plan to convene a Citizens Assembly and write up a new constitution, opposition protesters say that a new constitution will consolidate government power and severely shrink the political space for the opposition, making the translated we need a solution to problems that venezuelans confront every day, like shortages, insecurity, reporter but the streets have turned violent. Since early april, over 60 people have been killed and 1,000 injured as a result of protestrelated violence. Most protestors march peacefully, but a violent minority has prompted the government to call them terrorists. An intensifying crackdown has led to more than 2,500 arrests. Many of them are represented by attorney jorge ramos who runs a Legal Assistance group called the venezuelan penal forum. Ramos says theres a benefit for the government to detain people and the benefit is intimidating these specific groups of society, why . Not to demonstrate, not to say things about the government. Reporter but even intimidation tactics cant seem to quell the discontent of so many venezuelans, as the crisis bleeds into every aspect of life. Lisbeth vieras has worked for nine years as a taxi driver shuttling passengers to and from the caracas airport to support herself, her son and daughter glorybeth. She was never a fan of chavez nor maduro, but now that tourism and Business Travel has plummeted, she blames the government for sending the economy down the tube. translated there are a lots of changes. Two years ago, we could make three to four daily runs. Today, only one. Reporter now, vieras can barely cover the cost of food and her daughters law studies at university. But her daughters still studying, luckier than others. translated i have peers who cant pay for University Tuition and have to withdraw from their studies. Its more important to eat in this situation, than to study. Reporter as venezuelas crisis deepens, the chorus of voices calling for change grows. Michael penfold, a University Professor in caracas and a fellow at the Woodrow Wilson center, says that chavismo is failing to understand that political and Economic Conditions have changed. But the problem is that this revolution which right now holds a minority is running the country as if they still held a majority and as if they still had this hegemonic sort of impulse of Controlling Society and controlling institutions. Reporter opponents have protested delayed Regional Elections and the attempt to strip authority from the oppositionheld congress. But maduros decree to create a constituent assembly to draft a new constitution, a move they fear will favor only his priorities, was the last straw. This resident of a caracas barrio says it is yet another political distraction. translated you see a lot of problems here, and we know that this man is inventing fictions, instead of looking for solutions, hes looking to entrench himself in power. We dont want this, what we want are solutions in my family, five people have left the country. Fleeing what theres crime, you dont know when you leave when youll come back, i spent 18 hours to buy fo
