welcome to bbc news. 11 people from one family in lincolnshire have been convicted of involvement with a modern—day slavery ring. it follows one of the biggest police investigations of its kind. members of the rooney family ran a driveway resurfacing company, and targeted vulnerable homeless people as workers. but their victims were paid little or no wages, and suffered punishment beatings if they complained. they were also housed in squalid conditions detectives described as truly shocking. judith moritz reports from nottingham crown court. fathers, sons, cousins across the generations. 11 members of one family, whose cruelty has spanned the decades. the rooneys were the masters.

this is where they kept their slaves. they were forced to live in these caravans, in squalor and in filth, conditions not fit for human habitation. whilst those who controlled them lived in comfort and luxury. the rooneys had many victims, including this man, whose interview has been re—voiced to protect his identity. i've been on and off the streets for years, drugs and alcohol. i haven't seemed to be able to get settled. see, they've scarred me. sometimes i have flashbacks, and, you know what i mean, nightmares and that. i'm always wary about them. the rooneys were flashy with their money, going on holidays to barbados, and paying for cosmetic surgery. by stark contrast, the 18 men they kept as slaves lived in misery for years. one man was held for quarter of a century. his family gave him up for dead. patrick rooney was one of those

posing as a respectable businessman, laying driveways. but, in reality, the family used slave labour, forcing vulnerable men to work for little or no reward. one customer, who has asked not to be identified, remembers how the workmen appeared. they weren't treated as civilised at all. they were treated as if they were subhumans. i was truly astonished. there was no machine to strip the old tarmac off, nothing. these guys did it all by hand. and it was extremely hard work for them, i'll give them that. they didn't stop. they didn't have any breaks, anything. all they got was that we made them a few cups of tea, a few chocolate biscuits. they were delighted to get a cup of tea, because i knew and they knew that they weren't going to get anything else. not for the day. in contrast, the family lived lavishly. this expensive funeral for one relative showing their wealth.

in the local lincolnshire community, it didn't go unnoticed. the people they were preying on were the most vulnerable. they made a lot of money out of them, and the stories i was hearing about big washes of cash. bringing the 11 family members to book has taken several years. the police needed to win the trust of victims, who were very vulnerable. they were dirty, they were thin. the clothes they were wearing were terrible. and, when we took them to the reception centre, one individual used an entire bottle of shampoo, to try and make himself feel clean. to how they are now — they‘ re in employment, going to college, they're reunited with theirfamilies. it's absolutely heart—warming and amazing to see the transformation, and it makes it all worthwhile. they preyed on the homeless and the desperate, offering them shelter and work. but there was no dignity in this, only lives exploited and destroyed. judith moritz, bbc news, nottingham.

president trump is digging in over the war of words with north korea concerning their nuclear and ballistic missile programme. he said kim jong—un would truly regret it, and regret it fast if pyongyang took any military action against america or its allies. he had already tweeted that the us was "locked and loaded" if north korea chose to act unwisely. russia and germany have called for both sides to be calm. from washington, our correspondent nick bryant reports. after "fire and fury" comes "locked and loaded". not the title of some hollywood summer blockbuster, but the words of america's commander—in—chief, describing his country's state of military readiness. these are the latest pictures of b—i bombers stationed in guam. the motto of this squadron — "fight tonight." president trump reminded people of that on his twitter feed this morning. he is deploying social media

to fire off warning salvos. and again tonight, he ramped up the rhetoric even further, with this verbal broadside aimed at the north korean leader. this man will not get away with what he's doing, believe me. and if he utters one threat, in the form of an overt threat, which by the way he has been uttering for years, and his family has been uttering three years, or if he does anything with respect to guam, or anyplace else that's an american territory or an american ally, he will truly regret it, and he will regret it fast. as the government of japan deployed missile interceptors to guard against north korean rockets, international leaders essentially told both sides to cool it. translation: i believe that...

i'm firmly convinced that an escalation of rhetoric will not contribute to a solution of this conflict. translation: when a fight has nearly broken out, the first step away from that dangerous threshold should be taken by the side that is stronger and smarter. amidst this verbal brinkmanship, it has emerged the trump administration has been secretly talking to north korea about americans in prison there, and deteriorating relations. the news came as america's defence secretary emphasised diplomacy. you can see the american effort is diplomatically led, it has diplomatic traction, it is gaining diplomatic results. and i want to stay right there, right now. the tragedy of war is well enough known. it doesn't need another characterisation, beyond the fact that it would be catastrophic. holiday—makers on guam still seem unfazed.

but, amongst the beach reading this morning, a fact sheet from the guam government warning not to look at fireballs. in the last few minutes president trump has expressed hope that the crisis involving north korea will all work out. hopefully it will all work out. nobody loves a peaceful solution better than president trump, that i can tell you. hopefully it will all work out. the steel company tata has been given the go—ahead to separate its uk pension scheme from the rest of the business, which will help tens of thousands of the firm's workers. staff voted earlier this year to accept less generous pensions in return for investment to securejobs. the move is expected to clear the way for a possible merger with a rival german company. our correspondent wyre davies reports now from port talbot. tata steel had warned for years that its uk business was under threat, and it wanted to radically reduce pension benefits to workers, or face the prospect of having

to close it port talbot plant. for months, employees who stood to lose thousands of pounds from their retirement plans have been meeting to review their options. all of a sudden, you're coming to the end of your working life. you've got two years left, and you have to work another seven years in order to get what you've worked your entire life for, without any penalties. and they feel cheated. i've been there for 23, 24 years. you think you're going to be secure when you're 60, 65, and now they've taken that away from you. the £15 billion british steel pension scheme is one of the uk's biggest. around 130,000 members will be affected, and the new plan would see current owners tata paying £550 million into the restructured pension scheme. the scheme will also get a stake of one third of tata's uk business to help meet future pay—outs.

workers who sign up to today's proposal will have lower annual increases. other options include transferring into a personal pension scheme. or they can stay with the old british steel scheme, which is backed by the pension protection fund, and that is the really controversial part, because that is normally only available to companies that have gone out of business. the pension protection fund is there to protect the members, not the companies themselves. so i think the issue that everyone has is why should they be allowed to join the ppf, because the liability is with tata steel worldwide, which has plenty of cash, as we all know. although this agreement does protect workers' pension plans, it also makes the company, tata steel, much more attractive to a potential takeover or merger. and, with the german steel giant thyssenkrupp waiting in the wings, there will be renewed concerns about future job losses, and even closures,

at some uk steel plants, including port talbot. the german firm says it wants to consolidate european steel—making, but industry experts say that port talbot is in a relatively strong position. i think the immediate future for workers in port talbot is actually very good. port talbot has restored its competitiveness. it's been helped by the exchange rate against the — of the pound against other currencies. port talbot has been synonymous with steel—making for 70 years, and although only one fifth of the once—20,000—strong workforce still work here, today's deal on pensions should bring some relief. wyre davies, bbc news, port talbot. an oxford university employee has appeared in a us court accused of murdering a 26—year—old man in chicago. somerville college's andrew warren and us professor wymondham lathem are accused of fatally stabbing trenton cornell—duranleau in mr lathem's flat. in san francisco's hall ofjustice, mr warren declined to fight his extradition to chicago for questioning, and was remanded in custody. neither of the suspects has been formally charged. a 19—year—old british watersports

instructor has died while swimming in greece. he failed to resurface after diving into the sea, according to his employer. the former eastbourne college pupil's body was discovered on the seabed at a depth of around 30 metres. tributes have been paid online on social media. the results of the kenyan presidential election have just been announced, with the incumbent president kenyatta taking 54% of the vote, and the main opposition candidate, raila odinga,winning41i%. the president's critics say the election was rigged. but, as our africa correspondent alastair leithead reports, monitors say the poll was largely free and fair. uhuru kenyatta's supporters knew this was coming.

preliminary results had given their man an unassailable lead. but first, there was an electoral process to follow, and it was a lengthy one. the result from every county had to be read out, before the moment the nation had been waiting for. i wish to declare uhuru kenyatta as president—elect. after three days of holding their breath, kenyans have now finally had confirmation that uhuru kenyatta will have a second term in office, by a considerable margin. the question now is how the opposition will react in defeat, having claimed this was rigged. would they accept this result? will they challenge it in the courts? or will they go to the streets? before the results were even released, the opposition alliance had walked out, repeating allegations the vote was rigged. i think this has been an entire charade. this is a disaster.

they had run a parallel counting centre, and claimed discrepancies, that the election commission computer was hacked, that the vote was fraudulent. president uhuru kenyatta stepped up to acknowledge his victory, and spoke about unity, ten years on from the terrible ethnic post—election violence. i extend the hand of partnership, knowing fully well that this country needs all of us pulling together in order for us to succeed. these were the scenes in the stronghold of the losing candidate, raila odinga, in western kenya earlier in the day. a lengthy stand—off with police. there have already been a few clashes in the slums of nairobi. the fear is these ugly if isolated protests could spread, if the opposition decides to call its people out on the streets.

tonight, kenya is still holding its breath. that is a summary of the news. newsday is coming up at midnight. now on bbc news, it is time for newsnight. the war of words continues. or if he does anything with respect to guam, or any place else that's an american territory, or an american ally, he will truly regret it, and he will regret it fast. the north korean nuclear crisis keeps roiling away, with fresh threats today. is all of this making the actual use of nuclear weapons, for so long unthinkable, a real possibility? we speak to the man who advised president obama on arms control and wmds. acid attacks in the uk have more than doubled in three years. we've seen it on the streets, thieves on scooters throwing acid at people to steal mobile phones and handbags.
