A beautiful girl, her parents said, who would stay eternally young, loved by all and forever in their hearts. Lorna gordon, bbc news, barra. As with manchester, many londoners have reacted with defiance to sundays attack. But the Security Services are warning we may have to learn to live with the ongoing possibility of further violence from islamist extremists. Our special correspondent fergal keane looks at what longer term challenges this could present to our society and to our communities. The imagery of terror is becoming more familiar. Three attacks in less than three months, all by men who we re than three months, all by men who were willing to die themselves so they could inflict pain on others. Rightly, we speak of peoples resilience and there will to resist those who would make them afraid. But the public response to terror can be more complex. but the public response to terror can be more complex. I think its terror, buried i think its terrible, very little is being done. You send condolences. The suspicion, it does something to you, even though we dont want to admit it. No woman is about being scared and looking at people differently. Everyone does, i guess. In the 12 yea rs everyone does, i guess. In the 12 years since the 7 7 bombings, feelings of fear have dissipated. Inevitably the names of victims, the immediacy of the horror faded from the public mind but once again, Britain Faced Mass Casualty terrorism. The government is promising tough action. Theresa may says enough is enough, but suppose that the struggle against violent jihadism is a generational one, that the violence we saw on westminster bridge, in manchester, in london, has the capacity to stretch decades into the future. What are the human costs and the challenges to our society of that possibility . Terrorism leaves a devastating long term legacy. Jenny nicholson, aged 2a, was murdered on the way to work on 7 7. Grief is not something you can measure at all. Its something that is utterly felt and i think it becomes like a well. The water of grief can rise but it can also diminish from time to time. Its always there. Its always there, it never goes away and in a second, in a moment, something can bring it back. And of course, with every new terrorist attack, then, you know, it brings it back so you are forced to re engage with it. With sustained violence like that experienced in northern ireland, individual suffering inflamed communal division. Coming up here to see if we can give any help. What did you see . Ive seen nothing, only bodies lying there. Terrorism was not an event but a continuing tragedy. Trauma, working its way into the collective psyche, corroding trust. The main thing that a long term Terror Threat does to a society like the uk is to polarise it, to cause division, to divide people from different communities, make them suspicious of one another and make it more difficult for the society to be cohesive and at ease with itself. Theres no sign of it away any time soon. In other words, this is something that were going to have to learn to live with and cope with and deal with. But how . The ira moved towards politics. Not imaginable in the case of is, which regards mass murder as an end in itself. Patient, long term realistic approaches to containing the threat are more realistic than saying you can stamp terrorism out. Even though the ira and isis are very different groups, all those things in terms of how one response to terrorism seem to be echoed across generations. But that counsel of patience may be tested in the weeks, months, perhaps even years ahead. Fergal keane, bbc news, london. Six arab states, including saudi arabia, bahrain, the United Arab Emirates and egypt, have cut diplomatic ties with qatar, accusing it of supporting terrorism. Qatari diplomats are being expelled from neighbouring countries, while the airlines, etihad and emirates, are suspending flights to the qatari capital doha. The Qatari ForeignMinistry Says the measures are unjustified and based on unfounded allegations. Our security correspondent, frank gardner, has more. Saudi tv today, airing a very public quarrel between some of the worlds richest nations. Saudi arabia, bahrain, the uae as well as egypt have all cut diplomatic ties to qatar. Theyve imposed an air, land and sea embargo on the country, causing some panic buying. Theyre accusing the gas rich gulf state of funding terrorists and helping iran destabilise the region. Qatar strongly denies it. It was president trumps recent visit to riyadh that emboldened the saudis. Its leaders now feel theyve got the green light from washington to get tough on their rivals and adversaries. But qatar hosts us central commands airbase for the entire middle east and the us needs this spat to be resolved quickly. What we are witnessing is a growing list of some irritants in the region that have been there for some time. Obviously now they have bubbled up to a level that countries have decided they needed to take action in an effort to have those differences addressed. We certainly would encourage the parties to sit down together and address these differences. Six arab nations have lined up to accuse qatar and its ruling emir of supporting the Muslim Brotherhood and hamas to promote an islamist agenda across the region. Of supporting violent jihadists in syria, something the saudis are also suspected of. And of hosting the al jazeera tv channel, a constant thorn in the side of arab rulers. So how far will this go . Translation i dont think the uae and saudi arabia will, or want to, interfere to overthrow the regime in qatar. Theyjust want qatar to commit to whats been agreed on. Qatar has invested billions of pounds in britain. It owns the london shard, harrods, luxury hotels, property and bank shares. Qatars embassy in london is making no comment this evening, but this is an escalating row between close allies of britains in the gulf. Qatar will not be able to endure this sort of isolation for long and looming on the horizon is an important date on the calendar. In just five years time, the Fifa Football World Cup is due to be held in qatar. Already a controversial choice of venue, this would be all but impossible if this row is not resolved by then. Frank gardner, bbc news. The leader of the Scottish National party, Nicola Sturgeon and the Liberal Democrat leader, tim farron, have faced an audience in edinburgh this evening on a bbc Question Time election special. They faced questions on brexit, a second Scottish Independence referendum and social care. Our scotland editor, sarah smith, was watching. One issue, the most in the minds of the audience tonight, security. Tim farron was asked why he didnt support new internet surveillance powers. He said it would be counter productive. Powers. He said it would be counterproductive. The terrorists wa nt counterproductive. The terrorists want us to turn in on ourselves and to be divided as a country. They wa nt to be divided as a country. They want us to give up on our freedoms and liberties and those are the things we should not sacrifice otherwise the terrorists will have won. He was tackled on the economy and tax. How can the lib dems justify making every taxpayer pay 1p more tax . You can have platitudes from people who will tell you that they can solve the problem without any they can solve the problem without a ny extra they can solve the problem without any extra money or we they can solve the problem without any extra money oi we can they can solve the problem without any extra money or we can be honest and say that for the price of a Cup Of Coffee a week we can have the best nhs and social care in the world. The snp leader Nicola Sturgeon was asked how to deal with Terror Threats. Weve got to tackle and address extremism whenever we find it. And i believe very strongly that we have to do that with the muslim community. We mustnt scapegoat that community. She faced several hostile questions about her demand for another referendum on Scottish Independence. Continuing with independence and this time. Im not proposing it now, i accept that. When are you proposing it . At the end of the process. It should be our choice, when the time is right and we know what brexit means for the country, to decide the future of scotland. Education, the nhs and brexit all came up but what the voters here really want to know is how politicians are planning to keep them safe. Sarah smith, bbc news, edinburgh. The actor, peter sallis, has died at the age of 96. He was best known for his roles in Last Of The Summer Wine and as the voice of wallace in the animation series, wallace and gromit. Nick higham looks back at his life. Music theme from Last Of The Summer Wine. For more than 30 years, peter sallis played clegg, the mild mannered, flat capped philosopher in Last Of The Summer Wine. Stay. Steady. Go much of the series Innocent Charm came from peter sallis. Yes this is it this is the tree you can see Tollgate Church it happens sometimes in an actors life, if youre very, very lucky, that Something Special turns up. When i read Last Of The Summer Wine, i thought, this is it. Long before the summer wine, peter sallis was a familiar face. Great, good and just. On television, he played samuel pepys. And casanova in the heyday of studio drama. And he appeared in classic serials like the palaces. Im sorry, gromit. Then, in his 70s, those Nasal Yorkshire Tones became world famous thanks to the animator nick park. Its my turn for breakfast this morning, gromit. Id like a three minute egg. Steady on gromiiiiiiiiiiiiiiit Park Cast Him as the voice of His Plasticine Character Wallace in films like the wrong trousers. Wallace was charming, hapless and sometimes quite shrewd, playing comic foil to the lugubrious gromit. Peter sallis was an automatic choice for the part. Cracking toast, gromit. I feel very grateful, not only the richness and the charm that he brought to wallace, and the humour, but alsojust knowing such a lovely man off screen as well was wonderful, and a great privilege. Here we go, then. Few actors are lucky enough to win two such wonderful parts. Peter sallis was a modest man, not unlike the characters he created, but a talented one as well. Well, you said reverse. The actor peter sallis, who has died at the age of 96. Lets return to our main story and the London Bridge terror attack. There has been much praise for the Quick Response of the Emergency Services. But of course once the injured had been treated and taken to hospitals, Nursing Staff there then had to work through the night to treat often life threatening and life changing injuries. Daniela relph has been talking to two nurses donna adcock and Saskia Stephenson Who were called into work at University College london hospital. Instantly, my heart was pounding, and i was rushing around, wheres my car keys, wheres my bag, just wanted to get there and wanted to help. Anyone that we contacted, who was available and nearby, came. Itjust showed, with no question. The staff themselves were all geared up, they were very controlled, they were supporting one another, and actually the teamwork that was evident was really inspirational. Does it also have an impact when you know that youre coming in to deal with a terrorist related incident . Some of our families dont understand how it is that everybody else is moving away from an incident, and were driving headlong into it, do they . So that in itself can be a real sensitivity for us to manage, then, when we get home, as well. Having to explain to an older child why i have left them in the middle of the night and driven towards a Terrorist Incident is not an easy thing to do. Its unpredictable, its scary, everyone is aware that this is going on in central london, where we all are. What was it like for both of you when you got home . It must be hard to switch off. Absolutely, my mind was whirring for hours. I tried to go and get some sleep because obviously it had been a very long night, but i wasnt able to sleep for quite a while, it was just going over and over in my head. We do know that one of our colleagues was actually on the bridge at the time of the incident. He came in with one of the Emergency Services and continued on duty, volunteered and continued right through towards the end of the incident, which i found exceptional. And it was at the end of the incident, he started you could tell he started the process of the experience that hed been through. Your work over the weekend, that must make you feel very proud to be a nurse . Everything was just so well done, and everyone did such a fantasticjob. Im just really proud to work with this team, and they were great, everyone was fantastic. Thats it
