hello. you're watching bbc world news. i'm chris rogers. our top story this hour — closing in on the istanbul nightclub gunman. turkish officials want to identify this suspect who's thought to be behind the attack which killed 39 people. welcome to the programme. our other main stories this hour: "it won't happen" — donald trump rejects north korean claims it's in the final stages of developing a nuclear missile capable of reaching the us. and 100 years on, an appeal is launched to trace the relatives of soldiers who fought and died in the battle of paschendaele. i'm sally bundock. in business a record number of uk oil and gas companies went bust in 2016, but could this be the year the price of the black stuff bounces back?

and ringing the bell for 2017. where should you put your money this year? and will economists or fortune tellers have the upper hand on predictions? authorities in turkey believe they are close to identifying the man who killed 39 people in the attack on a new year party at a nightclub. security officials have released footage they say shows the suspect filming himself in the centre of istanbul. armed police have raided several addresses in istanbul and arrested 12 people. greg dawson reports staring directly into the camera, the face of the man turkish officials say is the main suspect in the deadly nightclub attack. this

footage, released by police, appears to show him filming himself on his home while walking through taksim square, one of istanbul's most busy areas. it is not clear when it was recorded. following a tipoff, armed officers carried out a raid on a house in the city monday evening. the suspect was not found but so far 12 people have been arrested in connection with the attack that the so—called islamic state says it was behind. they say it was revenge for tu rkey‘s behind. they say it was revenge for turkey's attacks on syria. the gunmen shot his way into the club and then shot 180 bullets in seven minutes, killing 39 people. the club, which sits on the bank of the river, is one of istanbul's most exclusive. it is now part of a growing listing places in turkey to be hit by deadly attacks in the last 12 months. many of the injured remain in hospital, including francois al—asmar from an aunt who says he owes his life to his

passport. the first bullet came from here. it passed from here, and the explosion, something explosion, and it passed by here. and it come here, but the passport, lebanese passport, saved me, saved my heart. now they believe they know what he looks like, turkish authorities say they hope to find the gunmen weekly and then establish if anyone helped him. we take a look now at some of the 39 victims of that attack, some two—thirds of them were foreigners. well, on monday the islamic state group also claimed responsibility for a series of car bombs in the iraqi capital. the most deadly hit a busy square

in the eastern shia district of sadr city. at least 35 people were killed, 61 injured. the so—called is says it specifically "targeted a gathering of shia". all this as the french president, francois hollande was the us president—elect, donald trump has dismissed north korea's latest claim to be developing a missile capable of delivering a nuclear strike against the united states. in a tweet, mr trump highlighted a boast in the north korean leader kim jong un‘s new year message that preparations for a missile launch had reached the final stage. mr trump's view on that: ‘it won't happen.‘ 0ur south korea correspondent steve evans has more from seoul. you and i spoke here on the bbc in november, shortly after donald trump

one and you predicted that we would hear this kind of rhetoric from kim jong—un at some point as america went through a transition. you think thatis went through a transition. you think that is all idiots? rhetoric matters, however. it is certainly rhetoric. 140 characters of rhetoric. 140 characters of rhetoric. it is clear stuff. it is those words, quote, it won't happen," from the president—elect. there is a political consequence because if it does happen within the four u—turn, democrats will say you said it won't happen but more importantly how is he going to stop it happening? there are all kinds of options you would imagine. 0ne maybe he does not think the regime will survive or that he does not think the technological ability is there to deliver on the threat. 0r the technological ability is there to deliver on the threat. or he may be thinking "i will sit down with

kimjong—un be thinking "i will sit down with kim jong—un over be thinking "i will sit down with kimjong—un overa be thinking "i will sit down with kim jong—un over a burger and persuade him to renounce the ambition." 0r, persuade him to renounce the ambition." or, and this is certainly ambition." or, and this is certainly a prominent inference in these parts, he is saying we. it happening if it looks likely. if you then talk to military experts, and i do mean ideological ones, i mean scientists, you asked them about the options and they see the options are limited because the north korean nuclear programme is buried, it is dispersed and it is protected. bunker buster bombs cannot be relied upon and special forces operations, you bombs cannot be relied upon and specialforces operations, you know, you cannot predict how they will go and you cannot bank on them. city experts then say what is much more likely to happen are things we may not even know about, the insertion of viruses in computer programmes, for example, like happened with the run, or maybe the assassination of scientists as well as is supposed to

have happened with the rhyme. the truth is, we just have happened with the rhyme. the truth is, wejust don't have happened with the rhyme. the truth is, we just don't know. have happened with the rhyme. the truth is, wejust don't know. —— happened with iran. in other news: several syrian rebel groups are saying they've suspended their preparations for the peace talks planned in kazakhstan later this month, brokered by turkey and russia. they blame violations of the ceasefire by the syrian government. a monitoring group, based in britain, claims government planes have carried out more raids on a district near damascus. israel's prime minister benjamin netanyahu has been questioned for three hours by police investigating allegations of corruption. he met the officers at his official residence. he has denied any wrongdoing — there've been claims he may have illegally accepted gifts from businessmen. hong kong's former leader, donald tsang, has pleaded not guilty to charges of corruption. he is the territory's highest—ranking official to face such charges. mr tsang is accused of two counts of misconduct in public office and one count of bribery — both relating to a luxury flat he was renting in southern china.

and sally is here with all the business news. we are focused on oil today and what this you will mean for the price of the black stuff. we had a very tricky year in 2016. the number of uk oil and gas companies going bust has reached an all—time high following the slump in prices of crude. that's according to accountancy firm moore stephens who say a total of 16 businesses became insolvent last year, an 8—fold increase on 2015. despite the recent increase in the price of the black stuff, atjust under $60 a barrel it's stilljust over half what it was in the summer of 2014. so could this be a year of recovery for the industry? given the fact that opec

given the fact that 0pec and non— opec oil given the fact that 0pec and non— 0pec oil producers have agreed on cuts to production to kick in this months of this year. we will have a discussion with an oil analyst later. annualised economic growth of 9.1% — that sounds pretty impressive, doesn't it? well, that is how singapore's economy performed in the fourth quarter of 2016 and that is much better than expected. so why did it do so well? sharanjit leyl will be explaining a little later in the hour. she willjoin us from our asia business hub in singapore. 2016 was a year of surprises and dramatic shifts in the global balance. we had the british vote to leave the european union and donald trump won the white house against all odds. so what's in store in 2017? 0ur asia business correspondent karishma vaswani took to the streets of singapore's chinatown to see what a traditional fortune—teller and a longtime economist are predicting for the year ahead.

thank you, sally. we will also be looking at the papers as well later. all of the international headlines. just turn our attention now to brazil. brazilian officials say 56 inmates have been killed in a prison riot. the fighting broke out between rival drug gangs at the jail in manaus in the north of the country. a warning — this report from our south america correspondent, wyre davies, contains some flashing images. local television pictures showed women and family members crying, screaming, outside the jail, as the riot broke out apparently during visiting hours on new year's day. the violence at the largestjail, in the northern city of manaus, involved rival gangs attacking each other with guns and other weapons smuggled into the prison. there were horrific reports of many rival gang members being tortured, and even being decapitated, after being taken hostage. as night fell, and armed police tried to regain control of the jail, reports emerged of the violence being committed inside.

translation: my son is an inmate there. the police won't care about him. i want to know how my son is. my son's in there. this is a bullet. a local security official said the death toll could be as high as 60. translation: there were deaths, unfortunately. we have some outside the prison, who were thrown from the prison by the inmates themselves. there have been escapes, we don't know yet how many. we're already looking for the escapees in the forest and highways. this is possibly the worst prison massacre in brazil since 1992, when 111 inmates were killed, most of them by armed police, as they retook the carandiru jail. many of brazil's overcrowded prisons are, in effect, run by powerful drug gangs, with the authorities unable to counteract the power in influence of gangland bosses, who run their empires from within.

so prison riots and gang—related massacres are increasingly common. 24 hours after the manaus riot began, some sort of order had been restored. but this was more proof that brazil's broken prison system is in desperate need of reform. do stay with us here on the programme if you can. coming up, a walk on the hilly site. what is it like to live on the steepest residential road in the world? it must be a nightmare. the japanese people are mourning, following the death of emperor hirohito. thousands converged on the imperial palace to pay their respects when it was announced he was dead. good grief. after half a century of delighting fans around the world, charlie brown and the rest of the gang are calling it quits. the singer paul simon starts his tour of south africa tomorrow, in spite of protests and violence

from some black activist groups. they say international artists should continue to boycott south africa until majority rule is established. teams were trying to scoop up lumps of oil as france recognises it faces an ecological crisis. three weeks ago, the authorities confidently assured these areas that oil from the broken tanker erika would head out to sea. it didn't. the world's tallest skyscraper opens today. the burj dubai has easily overtaken its nearest rivals. this is bbc world news. i'm chris rogers. the latest headlines: turkish officials say they're close to identifying the suspect in the deadly istanbul nightclub attack, as so—called islamic state says it was behind the shootings. donald trump rejects north korean claims it's in the final stages of developing a nuclear missile capable of reaching the us. the british government is launching an appeal to trace

descendants of soldiers who fought in the battle of paschendaele, in belgium, a century ago this year. it was one of the bloodiest battles of world war one, with 325,000 allied troops and 260,000 german soldiers killed in three months, and it came to epitomise the mud and slaughter of the trenches. robert hall reports. byword was slight and i was hobbling back and then a shell burst upon the boards so i fell into the bottomless mud and lost the light. there was not a sign of light of any sort. not a bird ora rat ora not a sign of light of any sort. not a bird or a rat or a blade of grass. the words of those who tried to sum up the words of those who tried to sum up the hill of battle of

paschendaele. three months when more than half a million manned died —— men. three months when the adelaide army fought an enemy — demand and the cold. a century ago, ypres was under siege. the north leading north climbed steadily to the german line. after the war, the british made this sanitised documentary about the battle. tales of personal heroism to distract from the ghastly reality. the uphill advances, the cold wire, machinery and gas .— coppermine. the city rebuild from total destruction, ypres will see a series of events built around remembrance and the health visitors understand what happened here. events will take

place over two days it will start with the last post cemetery at the menin gate. on a freezing night under the menin gate menin gate, the google sound for the fallen once again. battle of paschendaele is the loss of a lot of lives for us. a lot of people we commemorate the day after day and we want to continue the message that the last post has not forgotten. this summer 's commemoration will be a partnership with a city whose people have never forgotten. a new year's message by a government ministry in argentina has caused uproar because it excluded the disputed falkland islands from a stylised map of the country. former soldiers and social media users have criticised that message as offensive to those

who died in the 1982 war. the social development ministry has apologised — it says it it was a mistake. the islands are a british territory in the atlantic, claimed by argentina, where they are known as the malvinas. hundreds of people have been forced to leave their homes due to forest fires threatening parts of coastal chile. around 50 hectares of land have been affected near the port of valparaiso destroying dozens of homes. the bbc‘s tim allman reports. this whole area is now on red alert. a blanket of smoke covering large parts of valparaiso. outside the city, emergency teams do what they can, trying to bring these forest fires under control but the high temperatures, strong winds and dry conditions make thatjob all but

impossible. the flames have a ready reach the people ‘s homes. dozens of buildings, many built of wood, destroyed. for some it is too much to bear. people have been told to get out but they want to protect their property, notjust their lives. a desperate situation for eve ryo ne lives. a desperate situation for everyone involved. translation: my family lives here so i came to help but it is chaos, real chaos. everyone is out of their houses, they are being evacuated and their win keeps changing from one moment to the other so we have to remain alert. local sports centres and schools have been used as shelters. there have been power cuts and some injuries. investigators are trying to work out how the fire started at the question of when it will end is still unknown. the hot dry weather is due to continue. the threat to the people of valparaiso is not

over. in bangladesh, half of girls are married by the age of 18, according to figures from unicef. bangladesh has one of the highest rates of child marriage in the world. but as more and more women get a better education and earn their own money, they're refusing to stay trapped in violent marriages. kasia madera has the story of two women who found the courage to get a divorce, despite society's disapproval. the number of women getting divorced in bangladesh is increasing. it is a predominantly muslim country, and traditionally it has been difficult for womn to divorce their husbands. been difficult for women to divorce their husbands. but in 2015, things started changing. seven out of ten divorces granted in the capital were initiated by women. ayesha parvin is a vocational school manager. despite being abused, she really tried to make her marriage work. when she finally decided to get divorced, her own parents froze her out, and stopped speaking to her. a survey of over 20,000 women found

that a staggering 80% had suffered from domestic abuse. maleka lives in one of dhaka's many slum areas. she suffered domestic violence at the hands of her husband. bangladesh has one of the highest rates of child marriage in the world. most women don't get to choose who their spouse will be,

so when a marriage turns sour, many feel they have no choice but to stay with their husbands. but ayesha and maleka decided to defy social convention by ending their marriages, and both insist that they are much happier living alone. more women in bangladesh are choosing to do the same. baldwin street, in the city of dunedin on new zealand's south island, is officially the world's steepest residential road. at its steepest, the slope has a gradient of 35%, that's 19 degrees. it's a road that must strike fear into anyone delivering post or newspapers, let alone anyone on a pushbike. we went along to find out what it's like to live there. lean on me plays. you come to this road and it is like something we have never seen before. this trip is really...awesome, yeah. # lean on me...#

quite daunting, really, isn't it? # when you're not strong...#. love doing it. it is cool, though. big round of applause! i am dave cull, i'm the mayor of dunedin, and i do not get to walk up baldwin street that often. from the bottom you think, oh, yeah, so it is a bit steep. when you get halfway up it, like now, then you realise why it is the steepest street in the world. it's got a real novelty, and the jaffa race has put it on the world map, and it is quite a sight when you come here and you see all those giantjaffas bouncing down the road. # for no—one can fill those of your needs...# my name is dr kerry blackman. i'm a local historian. that photograph shows baldwin street in about 1900. individual 10—acre sections were not wide enough to allow a zigzag in a road.

my name's sharon hyndman. i have been a resident for 26 years. the street has definitely increased in popularity as far as tourism goes. we had about 20 tourists standing in our lounge one day because it rained and they had nowhere else to go. i'm brendon thompson and i'm the community constable for north dunedin. the street does tend to attract thrill seekers. there was an unfortunate incident some years ago where there was a fatality. two people got themselves into a wheelie bin and one of them died when they collided with a trailer. treat it with respect. if you attack it, you can get really, really hurt at the top. i have not always made it up, especially on the wet days, but it is always a good challenge. we have climbed the steepest street in the world — baldwin street, dunedin.
