welcome to bbc news. our top stories: president putin orders an investigation into the explosion that severely damaged russia's only bridge to the occupied crimean peninsula. war protesters take to the streets of tehran after demonstrations into their fourth week. —— more protesters. and funerals are held for the victims of the attacks of a knife and gun

attacks of a knife and gun attack at a nursery school in thailand. the russian president has ordered a full investigation into the explosion that destroyed part of his country's only road link to the occupied crimean peninsula. vladimir putin has also ordered the russian secret service to ramp up russian secret service to ramp up security on the bridge. ukrainian officials have welcomed the explosion without officially admitting responsibility. it is the bridge the kremlin built. and it was under attack. an explosion at dawn. this was the result. russian officials claim a lorry had been blown up here and that the fire then spread to a fuel train. whatever the cause, you could see the damage. this is the bridge that links russia to annexed crimea,

and parts of the road had collapsed into the sea. later, investigators announced that three people had been killed. they have opened a criminal case. the 12—mile long road and rail bridge is not only strategically important to the kremlin as a supply route, it is also a symbol of the russian annexation of crimea. vladimir putin opened it in 2018, getting behind the wheel to show that, as far as he was concerned, russia and crimea were joined for ever. very different scenes today. pro—kremlin commentators have blamed ukraine for the explosion, but there has been no claim of responsibility from kyiv. it is noticeable how the situation has changed here, and the messaging. a few months ago, russians were being told — by their leaders and

by the state media — that the so—called special military operation would be relatively brief and victorious. now they are being told that there are problems, that russia is losing ground, and today they learned about the attack on a hugely symbolic location — the crimean bridge. news of the attack has sparked concern amongst the public here. but the russians we spoke to had different ideas about how the kremlin should react. "it is worrying," stas says. "war is always bad. they should have done this differently, with negotiations." but olga says, "putin must respond. what a birthday present they gave him! we should blow up the train lines ukraine uses to get its military aid from america. this is nato�*s fault." but from vladimir putin there has been no reaction yet to what happened here. no hint as to how he will respond. steve rosenberg, bbc

news, st petersburg. paul adams is in kyiv and told us how the ukrainians are responding to this. ukrainians, in general, are absolutely cock—a—hoop. for them, this is like the sinking of the moskva — the russian flagship of the black sea fleet back in april. this is a real moment of national delight. just to give you a bit of an indication, the ukrainian post office has already announced that it plans to issue a postage stamp celebrating the hit on the bridge over the kerch strait. the symbolism of that attack is enormous here, too. now, experts i've spoken to have said that they think this was probably a result of an extremely expertly executed sabotage operation, almost certainly by ukrainian special forces. but a presidential adviser just about an hour or so ago said, no, this was actually the result of infighting in moscow.

was he trolling the russians, playing on signs of division within the russian defence establishment? we simply don't know. it seems, though, this was a very good day, though, for ukraine. now we can speak to the vice president and director of the security defence decision at the rand corporation. very good to have you with us, barry. what impact will this attack wmhmmdwmmbnmfi have what impact will this attack have on president putin's morale right now? i have on president putin's morale right now?- have on president putin's morale right now? i think it is another blow, _ morale right now? i think it is another blow, it _ morale right now? i think it is another blow, it is _ morale right now? i think it is another blow, it is more - morale right now? i think it is another blow, it is more of i morale right now? i think it is| another blow, it is more of the same, i think ever since in terms of sustained damage to pollutants morale, ever since the beginning of the successful ukrainian counteroffensive, really taking large amounts of territory and the russian forces are really on the run so this is just thought of another

low in that regard it as a prestige issue and also it strains their resupply to what putin considers his crown jewel and that is crimea. that is a really hard issue for him, so it has got to hurt but it looks like there is going to be more. the ukrainian forces seem like they are really gaining momentum.— they are really gaining momentum. ~ . ., momentum. what impact do you think this momentum. what impact do you thinkthiswill_ momentum. what impact do you think this will have _ momentum. what impact do you think this will have on _ think this will have on president putin's ability to resupply? president putin's ability to murmur?— president putin's ability to resu--l ? _, ., ., president putin's ability to resuul ? n, ., ., resupply? this alone may or may not have a _ resupply? this alone may or may not have a lot _ resupply? this alone may or may not have a lot of _ resupply? this alone may or may not have a lot of impact, - resupply? this alone may or may not have a lot of impact, i - not have a lot of impact, i think it constrains the russian forces�* resupply. agency reporting of other attacks on other russian rail network nodes and so if that continues it is going to be much harder for russians to resupply their forces and if those forces are getting beat and getting killed and wounded and they are

retreating, so it is sort of all coming together and too early to use the word disintegration but there are a lot of indicators that russian forces in occupied territory in ukraine are really damaged, the morale is down and the conscripts that we have seen mobilised in a couple of weeks, they are not going to make it any better. they are not going to make it any better-— they are not going to make it an better. , ., , any better. president putin has made nuclear _ any better. president putin has made nuclear threats - any better. president putin has made nuclear threats on - made nuclear threats on multiple occasions, how seriously should those threats be taken, do you think? it is a talkin: be taken, do you think? it is a talking point— be taken, do you think? it is a talking point he _ be taken, do you think? it is a talking point he uses - be taken, do you think? it is a talking point he uses often. i talking point he uses often. russia does not have a lot of instrument to use to advance his goals and this is a big one, so he used it at the beginning of the war, he used it in 2014 when he invaded crimea and his used it since the beginning of the war so i think we need to take it seriously, not ignore it. be attentive to it, think about

how he might handle it but most importantly think about how he might deter in my view the actual is quite low. i don�*t think he wants a war with nato at this point which would be one of the potential scenarios, that his forces can�*t even handle ukraine very well and in addition if he used a tactical weapon there would be radioactive fallout, the wind likely would bring that fallout over russians, killing many russians, i don�*t think he wants that and then also it would make the area that was attacked uninhabitable for a very long time to come. so i think the us and allied approach to not back down, take it seriously but do not back down and keep doing what we�*re doing an ukrainians to keep doing an ukrainians to keep doing what they are doing, i think that is definitely the right approach.— think that is definitely the riuhtauroach. ., ~ , right approach. thank you very much for your— right approach. thank you very much for your time. _

revolution, the prosecutors said that this was on social media, on websites like instagram as well as on street boots and by distributing certain pamphlets. this was possible because of the 2020 national security law that made it easier to prosecute protesters. but what is different here as it is the first time that had been used against teenagers. thejudge in their sentencing said that they did take into account the age of the protesters and that is why the sentence has been capped at three years detention and why they are being sent to and why they are being sent to a detention centre for young people, also known as training centres as opposed to a jail but they said the issue was that even if they managed to influence one person, that would have undermined the stability of hong kong, as well as the safety of the residents. and can you remind us of the context of the national security law and why it was introduced?— security law and why it was introduced? ., , introduced? you will remember that there _ introduced? you will remember that there were _ introduced? you will remember that there were widespread - that there were widespread protests in hong kong in 2019 and those were ignited because

of an extradition bell that was introduced that allowed china to extradite people from hong kong and have them prosecuted in mainland china and that was seen to undermine and threaten the principal of one country to states in hong kong. those protests lasted a long time and there was a violent crackdown against those protesters and china believed that this would make it easier to quash those protests as well as safeguard their influence over hong kong. it did things like make succession, undermining the government, colluding with foreign forces, it made those things are legal and meant that they were able to put protesters as well as opposition lawmakers in jail for the rest of their lives stop it also was a political tool because then those people couldn�*t stand for office ever again and from the looks of it, it has worked. those protests did diminish and now many, more than 100 people, have been put

injail than 100 people, have been put in jail because of it.— in jail because of it. thank ou, in jail because of it. thank you. our— in jail because of it. thank you, our reporter- in jail because of it. thank you, our reporter azadehl you, our reporter azadeh moshiri there. funeral services are being held for dozens of victims of a knife and gun attack on a nursery school in northern thailand. 24 children and 12 adults were murdered by a former policeman on thursday. 0ur south east asia correspondentjonathan head sent this report. all these young faces as they were in life, as theirfamilies would like to remember them. 0ne wall of the temple has been turned into a shrine to what is now a lost generation for this village with loved toys, stuffed animals and, for this boy, a school uniform he�*d onlyjust begun wearing. kanjana and sittipong are saying goodbye to their only child, three—year—old hubet, one of the youngest victims. they rushed back here on news

of the attack from another province where they�*ve been working. translation: he was a very cheerful boy. i everyone admired him. i see you�*ve been holding this blanket ever since we first saw you. and tell us about the blanket. you know, this is the blanket he really loved. it always had to be a red blanket. he loved the smell of it. floral tributes have come from all over the country. arranging them properly is one of the manyjobs taken on by volunteers in the village. then, the start of a funeral which is expected to last for four days. this is a holy water pouring ceremony for which people queued on their knees inside and under a fierce tropical sun outside. funerals in thailand are always a community affair, and it seems that pretty much all the residents of this village have come to be a part of this one. it is a way of sharing the grief, of course, of consoling the parents, but also of acknowledging

that these dreadful killings have affected everyone. then, it was the turn of kanjana and sittipong. this young couple left their village in search ofjobs they hoped would provide a better life for their son. those hopes have been cruelly dashed by an attack no—one could have foreseen and which no one can understand. jonathan head, bbc news, north—eastern thailand. this is bbc news. our main headline — resident print orders an investigation into the explosion that severely damaged russia�*s only bridge to the occupied russian peninsula of crimea. ten people including a young child and two teenagers are now confirmed died after an explosion at a petrol station in county donegal in ireland on friday. from the scene — the village of creeslough — our ireland correspondent

chris page reports. this small community has been caught up in a wave of devastation and desperation. the rescue efforts became a recovery process as the day went on. the sight of ambulances leaving — a sign that there was no expectation that more survivors would be found. from the moment it happened, blown—out walls, a crumpled roof and tonnes of rubble showed this was a lethal explosion. like a bomb going off and a sonic boom accompanying it that shook us to the core and immediately, wejust — the people who were there, we alljust waded in to try and help and try and get people out of the building. the building was very precarious. it was very, very dangerous. there were flats above the garage shop, which largely collapsed. several times, the emergency services asked for silence so they would be able to hear anyone who was trapped. eight people were taken to hospital. one is in a critical condition.

what�*s really striking in the village is the quietness, the stillness, even. the emergency services are continuing to carry out their search and people have gathered to watch, wait for news, but you get the sense that they can�*t really take in that some of theirfriends, relatives, neighbours went to the local shop on a friday afternoon and lost their lives so suddenly. all those who were killed were from the area. there are no outstanding reports of unaccounted—for persons. the ten casualties are four men, three women, two teenagers — a boy and a girl — and a youngergirl. this evening, the leader of the irish government came to meet firefighters, police and paramedics. he said the nation was mourning. words on their own will not console someone who has lost a loved one.

and i think wejust have to be with them. our thoughts and our prayers are with you. and will be with you for quite some time. rural county donegal is often thought of as the essence of tranquillity. an idyllic retreat. tonight, widespread grieving has begun, coupled with an intense feeling of disbelief. chris page, bbc news, creeslough. breast cancer is the leading cause of cancer —related deaths among women worldwide and while screening mammography is available, there is an ongoing interest in improved early detection. a new fast, free blood test has recently been introduced in singapore. we can speak to doctor sarah loo at one of the hospitals offering this test and doctor loo joins us from singapore. what does this new way of screening

news. thanks for watching. this is bbc news. after what�*s been a wet week for some, saturday was a lot quieter. 18 celsius in the south, nearly ten hours of sunshine and only around nine millimetres of rain and the reason was this area of high pressure ruling the roost. but these weather fronts are now starting to nudge that high pressure system out the way, so for the day ahead, increasing amounts of cloud, wind and rain. but ahead of it, we�*ve still got starry skies and through the night, temperatures have been tumbling away — within two or three degrees of freezing in some rural areas by morning, notably of england and wales — so a touch of grass frost, a little bit of mist and some fog around where we�*ve got the light winds but the winds far from light further north and west — gales or severe gale—force winds are forecast for the day head — that�*s gusts of 60 or 70 miles an hourfor parts

of the western isles, the northern isles, too. starting to throw in this really quite heavy rain, several hours of it, across scotland and northern ireland. with it, some squally winds and hill fog, eventually pushing into north—western parts of england and wales. ahead of that, we�*ve got the early morning mist and fog to clear but we should hold onto hazy sunshine across central and eastern areas. 17 or 18 and feeling quite pleasant but clearly, with the cloud, the wind and the rain elsewhere, temperatures will be held nearer 13 or 14. now, the progress of that weather front will continue through the evening and overnight, becoming stuck across southern and eastern areas, but it will be milder through the coming night so, as we go towards monday morning�*s rush, we may well have a band of wet and relatively breezy weather to content with in southern and eastern areas. it�*ll be pretty miserable during the day ahead with that rain. then, showers follow on that north—westerly breeze, so temperatures taken down a degree or two but some good spells of sunshine and just the odd shower coming through on that brisk wind which will start to ease away. it will initially be really quite windy across even the north on monday morning

and then, that eases away and we�*ve got temperatures falling low once again with a touch of frost potentially in a few spots as we head towards dawn, so that�*ll be more widespread. but then later in the day, we�*ll start to pick up more cloud and then by wednesday, the next weather front arrives to bring rain, particularly across the northern and western half of the uk — that�*s this weather system here. but it�*s all eyes out to the atlantic for later in the week when it looks as if we can have a very deep area of low pressure moving in with a lot of wind and rain associated with it. we�*ll keep you posted.
