police are expected to continue questioning a number of people arrested in connection with the killing of pc andrew harper, who died after being apparently dragged under a vehicle and hit by another in berkshire. newlywed pc harper has been described as a highly popular member of his team. flags were flown at half mast at police stations across the thames valley force area. daniel sandford reports. on a rural stretch of the a4 outside reading, police officers doing what they dread — investigating the death of one of their own. pc andrew harper, 28—years—old, married to his wife lissie just four weeks ago, described by his chief constable as highly regarded, popular and a significant loss to the force. the officer was well known across the force. you know, so, it's felt very personal, despite the size of the force, it's felt very personally by the whole of the police family.

pc harper was responding with his crewmate to reports of a burglary late last night, a routine call that has ended in tragedy. yellow marks on the road made by scenes—of—crime officers give an indication of what happened here. pc harper appears to have been struck by a vehicle at the bottom of landon‘s hill and then dragged across the busy all, being left where those blue forensic tents are at the bottom of ufton lane. ten people have been arrested on suspicion of his murder. they are all male — the oldest is 30, the youngestjust 13. this evening, there was a heavy police presence at this caravan site, which police said formed part of their investigation. well, the murder of pc andrew harper is a mindless and a brutal crime, and obviously all our thoughts are with his family, his friends and his colleagues. the sense of shock and expressions of sympathy for the officer's death were universal.

my condolences to andrew harper's family and his colleagues, who must be absolutely devastated. he was doing his duty, examining, apparently, what had happened at a burglary, and was killed in the line of duty. as flags flew at half mast on the force's stations, the chief constable said that he felt violence against the police was increasing, though pc harper was the first to die at work since pc keith palmer was killed in the westminster bridge attack. he leaves behind his new wife and a wider grieving family, who said today that they were devastated. daniel sandford, bbc news, ufton green. now on bbc news: our world. in northern europe's lapland, temperatures are rising faster than anywhere else in the world, threatening the livelihood of its indigenous sami people. lapland is europe's

great last wilderness. it stretches across norway, sweden, finland and russia, north of the arctic circle. the far north of finland is the home of the sami, europe's only indigenous people, who still live off the land. but the life of the sami people is changing. climate change is affecting the arctic more than any other part of the earth. you can't rely on that you know how nature acts or how animals act because everything seems to be changing. the melting ice is opening up opportunities for shipping routes and there is talk of a new railway. it's the worst nightmare we are facing at the moment. which could threaten the sami

people's way of life. how can you put a price tag for a culture? we have come to lapland to talk to sami women about the challenges they face. nature gives if we give back. we can't just take. anna comes from a family of sami reindeer herders who still make

a living off the land. it's the start of the calving season and anna is checking up on the reindeer with a finish elective. the reindeer are about to give birth. these are extra feed pellets needed for the mother reindeer. so that they are in good condition. eero is the herder of this fence here. he is the husband of my niece. female reindeer have antlers during the winter and during the spring so they can chase away the male ones from good

food places, places where the reindeer moss is growing. these reindeer are female and they are about to give birth in a couple of days, some in a couple of weeks. they are so beautiful. reindeer herds roam free in lapland but when it's calving time, and anna's family fences them in to make sure the reindeer get enough food before the calves are born. over the centuries, sami people have made a living from reindeer herding. it's still a key part of their culture but now, fewer than 10% of them are involved in it.

reindeer herding is getting much harder. normally, there would be a lot more snow on the ground in the forest at this time of the year. but the climate is changing and it's threatening the family's heard. usually winter came in the end of october and now it can be in december. during the winter, there can be really warm periods that get the snow to melt. winter should be approximately nine months of the year and now it's maybe six months. temperatures in the winter fluctuate a lot more than they did in the past which is making it more difficult for reindeer to find food. usually, reindeer can dig through any amount of snow. so whether it's two metres, it can smell the reindeer moss and find itand dig it but when the snow melts, then this food, the basic

best food of reindeer, this reindeer moss, freezes, the reindeer can't dig it. they can't even smell it through the ice. that's starvation then. starvation means the reindeer herder has to take extra food. and of course, then it affects the income of reindeer herder. the number of reindeer herders is decreasin in finland. over the last 20 years, it has declined by almost half. now there are fewer than 5,000. many find it difficult to cope with the huge amount of unpredictability and reindeer herding posed by the changing climate. you can't rely on what used

to know about winter, our winters are. you can't rely on how nature acts or how animals are, because everything seems to be changing. people who live from the nature, sami people over here, have adapted and adapted over decades, almost centuries, i'd say. life here has always changed. but then we are reaching the point where these changes are not such things that you can add up to. people don't feel safe anymore and that starts to affect their mental health.

100km from anna's reindeer, in the far north—eastern corner of finland, close to the russian border, heini lives in a very remote house. the nearest supermarket is 90km away. most sami people in northern lapland live in places like this and they are very much connected to their natural environment. we built this house ourselves and i think log house itself is eco—friendly. we heat the house with wood but we do have running water and electricity, like in any other house. we are no eco—warriors, we are just ordinary people who wants to do our best. in early spring, heini and herfamily drink birchjuice. she usually start tapping the trees in may. but this year, for the first time,

the juice was ready in april. we get winter very late. it can be december that we get permanent snow. for instance, this february, spring comes very early so we have shorter winters. here are photos of my family. here are my grandmothers. and here is my great—grandfather. he is icefishing here. he is doing traditional ice fishing. heini is an artisan.

she makes a living by teaching traditional sami handicrafts. what i'm making here is a saamcic. it's a married women's hat. when women get married, she will have this crown for herself. it is as a crown. the saamcic is the most the most difficult handicraft i have tried and this is truly, truly very difficult handicraft. traditionally, every woman did handicrafts but not this one, because this was special. only some handicraft masters were doing this. heini uses reindeer skin to make shoes. but more rain in the summer has affected her ability to produce them. here are my latest. ijust made this ready, these we were waiting for years

in our shed for me to make these ready. this, i made these for myself. they are a little more fancy. the reindeerfur shoes. and these are already too small for my children. here is how we do it. we just, we skin the reindeer legs. then we just put them to dry like this. this is how it should be. here we can see moulded ones. it tells us that the summers are more wet than those are used to be. five hours‘ drive to the west, close to the norwegian and swedish borders, alen is a northern sami handicraft master.

she's 8a—years—old and she's visiting her niece to make traditional sami clothes with her.

climate change is damaging traditional sami livelihoods. but that's not the only threat. as temperatures rise and the sea ice melts, there's now the opportunity for a shipping route to open through the arctic. and plans are being developed for a railway to be built across lapland, threatening to cut through reindeer herding territory. finland's ministry of transport favours the route from rovaniemi, the capital of finnish lapland, along the shore of lake inari, and terminating in kirkenes in norway. supporters say the railway will boost lapland's economy, but the finnish government says no decision has been made on the construction of the railway or its routeing. but the sami parliament is fiercely

opposed to the plans. an arctic railway through rovaniemi to kirkenes, through our very heartlands of three different sami language groups in finland would be such infrastructure which will be the end to the sami culture. we live from the nature and it will cut the reindeer grazing areas into two. there will be more forest logging, for example. it will be transporting oil and gas products from norway and russia. it will bring the mining industry to the sami homeland area in finland. it's the worst nightmare we are facing at the moment, a concrete one. of course, climate change is another one. but it's not as concrete as the arctic railway.

heini, the handicrafter, who lives close to the russian border, has found out that a proposal for the arctic railway has been included in the development plan for finnish lapland. those plans i have seen. so it seems like it would go straight through our house. and my opinion is it would be a genocide. if the plans for the railway are approved, it's likely that heini would be forced to move. it's a painful reminder of the past. heini is a skolt sami. many of her people were forced leave their ancestral homes in russia and resettle in finland in 1944. all these kind of mining plans are our big nightmare here. yeah, we're very afraid of those.

that is why skolt samis had to move after the second world war. nazis did want to have this nickel mining in petsamo. we are only few. in finland skolt samis are around 600. and everyone has kind of tried to work to maintain the culture, keep the language alive. and if we have to do fight against this kind of international greed it takes too much of our time and energy away. everything is only measured by money. but how can you put a pricetag for our culture?

back in inari, anna is getting ready to go ice fishing. we are trying to put the last hooks in. anna does fishing all year round. and she takes great pride in supplying her family and friends with fresh fish. now the bait is in the hook. so the weight takes the bait down there in a good depth and this is how it stays. the stick stays there because this is holding or however big pike there will be. and then, well, tomorrow morning i will come and check if there is movement in there.

20 years ago, the lake would freeze over by the end of october. last year, anna had to wait until the middle of december before she could to go on the ice. and the ice starts melting earlier than it used to in the spring, making it increasingly dangerous to fish. the new conditions, of course, the people need to learn again to get to know them. so some people drown when learning. and that's, of course, a tragedy every time it happens. sami people are people of winter.

if the winter disappears it would be really strange, really hard to continue on the cycle of the year that doesn't have the real cycle. if the fishermen will adapt, then maybe the fish won't adapt to warming waters. so my biggest fear is that fish will disappear. one fall, one winter the nets will start being empty. anna believes that reindeer herding and fishing wouldn't survive if the arctic railway is built and new mines open up in the area. what is the reason for these building plans? it is the greed of people, big companies want to give more profits to their shareholders.

we need to be and we have to be active in this fight to save our world, to save our reindeers, to save our clean drinking water and where the fish can live and this... itisa... it's a trade of, like, both ways. nature gives if we give back. we can't just take. will climate change destroy the forests and the lakes in europe's last great wilderness? willa new industrial railway

wipe out sami culture, or will it bring jobs and an economic boom to northern lapland ? we don't know. for now, the questions remain unanswered. hello there. we can all look forward to seeing some sunshine this weekend. it was a poor day though on friday, especially across england and wales, the wettest weather in snowdonia. that rain—bearing weather front is putting away from the south—east of england but this area of low pressure is going to be the one constant right the way

through the weekend. that will focus the showers towards the north—west of the uk — some of them will be heavy. we'll get some sunshine, yes, but they will be accompanied by some blustery winds as well. those showers continue into the morning, these are the temperatures first thing, 12—15 degrees, but some heavy showers from overnight especially in scotland and the north—west of england. it will be western scotland and northern ireland that sees the bulk of the showers on saturday, wetter weather in the north—west and the winds really picking up later on. one or two fleeting showers for england and wales but not many, good chance it will stay dry at lord's for the cricket, but we will have these strong winds, not as strong as last weekend, and those temperatures back into the low 20s now that we have the sunshine across eastern parts of england. those showers, though, continue in scotland and northern ireland again, heavy and thundery, gusty winds as well, we have thickening cloud across southern counties of england, maybe threatening a bit of rain.

in between, clearer skies and temperatures around 11—13. the wetter weather in the south and south—east courtesy of this weather front here, that should pull away on sunday morning. still got that area of low pressure, it is a bit closer to scotland this time, and again it will focus the more frequent and heavy showers into scotland, into northern ireland, again some thundery downpours, gusty winds too, probably a few more showers in northern england, north wales, the south—west of england the best of the sunshine, and dry weather through the midlands and eastern england. strong, gusty west to south—westerly winds, probablyjust taking the edge of the temperatures but sunday is probably going to feel quite similar to saturday. as we head into the beginning of next week, we still have an area of low pressure but it is starting to move away from scotland slowly but surely, the winds beginning to ease down a bit as well. there will still be a focus of heavy showers across scotland and northern ireland, and a few scattered showers coming into england and wales, always heavier further north. some spells of sunshine around again and those temperatures are still 16 degrees in the central belt, to a high of 21 or so in the south—east of england.

further into next week, we will find some spells of sunshine. warm in the sunshine, temperatures not particularly impressive for the time of year, there will be some showery bursts of rain, mainly in the north and west, the winds, though, should be lighter.
