a clarification was quickly issued, linked to the original tweet, and explaining the tweet. and then the following day it was deleted. that error led to cries of fake news and the charge was levelled again after this shocking video featuring soldiers in cameroon began to circulate widely injuly. soldiers in cameroon began to circulate widely in july. these women and children are being led to their deaths. some claim to this atrocity took place in mali. others said it was filmed in the far north of cameroon, where government soldiers have been fighting boko haram since 2014. the story was taken up by bbc world news's investor —— investigation strand. thank you for coming on newswatch. when the video went viral, what was the response of the cameroonian government? well, initially the

cameroonian government denied that these were cameroonian soldiers, that it was... that this killing happened on cameroonian soil and they continued to deny and deny and call this fake news. so usually you would expect that with the kind of clues we had, which had to do with the uniforms of soldiers were wearing, even the ammunition they had on. the government said that this was not typical of cameroonian soldiers in the far north of the country, where this video was recorded. but that is where the investigation came in and we were able to uncover that is indeed actually was the case. and talk me through some of the other things that you set about proving to show this video was authentic, the uniforms was one. we have been watching some of the footage showing how are you pieced together the story while you were speaking. what else did you look at? well, first of all, the location. so, to find out where it was, you know, there was a

lot of conversation going on involving researchers on twitter, people going out, this was in cameroon, listening to the soldiers talk about the people, the women in the video, accusing them of being members of boko haram. so that was already a clue. there are only four countries fighting boko haram, three of which are french—speaking. but then going on using some of the clues like in the background, there isa mountain clues like in the background, there is a mountain ridge, so using that ridge line the investigators were able to match it to a town in northern cameroon. so, from there, they were able to use tools like google earth and online platforms, open—source techniques to match it. so finding the location, using google maps, and looking at the buildings that appear in the video, the dirt track as well that these

people were walking on. lots of these clues piecing together. can i ask how long it took, verifying this, that topography, looking at shadows at no time of day. how long did it take? it is painstaking work. this started injuly. it took a few weeks, close to 15 people who worked on it in the bbc and outside. so, painstaking work, daily work that had to involve putting heads together. some people were not particular experts. you know, in their day—to—dayjob. these were people passionate about using open—source techniques and spending time on it to bring out what we have in this investigation. as you mentioned you are gathering information from the public. are there dangers in crowd sourcing this work? absolutely. i think we talk about the fake news phenomenon which the cameroonian government as well mentioned when they were denying this claim, so obviously there are

lots of videos going around on the internet, on social media and it is very difficult to verify a lot of them. but at the same time there are a lot of tools. the same way this video has been verified. there are lots of tools that the average person can use and learn to work with to verify these videos. so as much as it is difficult to verify things nowadays there are also solutions to this. tomi oladipo, thank you so much. now, one concern that is regularly raised by newswatch viewers is over interviews with people who have just undergone all witnessed traumatic events such as a terrorist attack. after last yea r‘s events such as a terrorist attack. after last year's terrorist attack at the manchester arena number of viewers posted online there are objections to how the story was being covered by some members of the press. a twitter user called laura said she had to turn the tv off... and sue agreed...

well, the bbc has developed new training for its journalists on how to handle such interviews and to tell us more i am joined by senior reporterjoe healy and from salford judith moritz. judith, first, you reported on the aftermath of the manchester are ringing —— arena bombing. what were the experiences of some of the survivors and relatives who died? i think in the first moments, the first day, couple of days of the attack, it was a very intense time. it was relatively chaotic. news was very quickly rolling round the clock. you spoke there are about people seeing those who were traumatised being interviewed at the scene. i got to know some of those who were directly involved, some of the family is

particularly who lost loved ones in the attack. and it was only by talking to them over a longer period that we started to build up trust with each other and a relationship which i am pleased to say in some cases continues until today. and that was one of the lessons i learnt through reporting the manchester arena attack, was that this was not something that was appropriate for us something that was appropriate for us to turn up and report on leave and forget about. it is certainly here in manchester and beyond still an attack along with many others which resonates, which has left people's lives change forever and we need to continue telling a story. you have written a book and develop training for the bbc about how to speak to people who have gone through this kind of trauma. so many of us are regular can work so closely with people who are emotionally vulnerable. they are

very much at the heart of the course. the message to reporters is do yourjob, do it well, do no harm. it is about as well as being a human being being professional. so we look at openness, honesty, transparency at openness, honesty, transparency at managing expectations and our use of body language and language, the all important skill of listening to what people are trying to tell us. getting facts right, the basic trust when people have entrusted their story to us. and we apply this sort of good practice to each step of the reporting process. so to approaching the relationships that we create, to interviewing, to filming with them, which is often out of their comfort zone, and to writing about them and framing their stories. judith, can you tell me more about what happened after the manchester arena bombing? we after the manchester arena bombing 7 we know relatives did report being... getting really interested questioning in the immediate

aftermath by some journalists. we know because the family spoke to lord kerslake who produced a review into the arena in which they were damning about the treatment by some parts of the media, press reporters turning up unannounced on the doorstep, they said it was very intrusive. one family told me that in fact their children had discovered that their brother had died by reporters coming to the door. and that prompted us at the bbc to see whether we could do something about this. whether we could put together those experiences to learn from them and to teach journalists, not just to learn from them and to teach journalists, notjust within the bbc, but externally as well, through the bbc academy, about the way things are done and shouldn't be done, and to see whether there can be some sort of improvement. joe, we know in the aftermath of these terrible incidents journalists have a duty to report. what is the view now on the wisdom of broadcasting interviews with relatives who might

say they are willing, but they break down in the interviews, and it does distress viewers who feel the bbc perhaps should be broadcasting this7 so, parents whose children, and number of parents whose children we re number of parents whose children were killed, children whose parents have died, and survivors of abuse have died, and survivors of abuse have gone on film for the course, they were all interviewed by a number of reporters at a time of great distress, and on film they speu great distress, and on film they spell out what they like and dislike about that process. a teenage girl whose mum died, she says don't switch the cameras off because i consider that a disservice against not showing the rawness of my emotion. a young boy who was 12 whose dad died by suicide, he says actually i need a minute, i need a break. so you can't put these families together. everyone is different. and it is so important to treat them as individuals and to listen to how they want to be treated. and that goes back to preparing them, talking to them and giving them control. judith moritz

and joe healy, thank you both so much. thank you for all your comments this week. do call us with your thoughts on... or e—mail... comments this week. do call us with yourthoughts on... or e—mail... we are on twitter... and have a look at our website... that is all from us. we will be back to hear your opinions about bbc news coverage again next week. goodbye. hello, good morning. friday felt a little bit more like autumn because we had cooler air coming from the north, not surprisingly, the highest temperature was on the south coast, here in hampshire. still 19 degrees, pretty good. over the weekend, we've got high pressure close enough by, that whilst there will be some showers around, for the most part it will be dry with sunshine at times. but it will probably turn cooler as the weekend goes on. pretty cold at the moment, though, underneath that area of high

pressure with the clearer skies. we've got more atlantic winds across the northern half of the uk and a weak weather front as well. that's where the we have this band of cloud and patchy rain. ahead of it, maybe one or two showers for scotland and northern ireland. more cloud and quite a strong westerly wind, too. england and wales, the winds are lighter as you head further south. there will be a lot of sunshine. after a cold start, we will see highs of about 18 degrees and it should feel quite pleasant as well. not quite as warm for scotland and northern ireland. we will see the rain coming in to scotland in the evening, perhaps into northern ireland. as it moves southwards, though, the rain peters out again. more a band of cloud heading down into england and wales. and because we have more cloud debris overnight, if you like, it won't be as cold, saturday night into sunday morning. it will feel chillier by day, mind you, because we've got more cloud is moving southwards. behind it, some sunshine and some showers blown in on a brisk north to north—westerly wind.

the bulk of the showers i think will be in the northern half of scotland. but temperatures are going to be lower across the board. only around 12 or 13 degrees in scotland and ireland. 14—16 in the south. that chilly north to north—westerly airflow is with us for the start of the new month. but then, around the top of this area of high pressure, we're going to change the wind direction across scotland and northern ireland, replacing a chilly northerly with more of an atlantic westerly, bringing some rain to the north—west later. sunshine for england and wales, still not very warm, 14 degrees at best. the odd showers possible towards those north sea coasts. this band of rain in the north is initially quite heavy around that weather front there. but it will topple southwards and then again it is a familiar story. everything just weakens. the rain just tends die out and there won't be much of it left on tuesday for england and wales. but there will be much more cloud around. we'll get a bit more sunshine for scotland and perhaps northern ireland. so a different feel to weather probably on tuesday, those temperatures beginning to risejust a little bit, but there will be much more cloud. we are left with a cloudy westerly airflow as we move into tuesday and wednesday. that means higher temperatures by day, higher temperatures by night, but but probably not as much sunshine. welcome to bbc news,
