to world news today. the italian government says it's ready to ban large cruise ships from the giudecca canal in venice after a huge cruise ship collided with a dock. the msc opera collided with a smaller boat at the san basilio docks along the giudecca, which provides access to the popular st marks square, and it's who's by large cruise ships has been criticized locally. the environment minister sergio costa says they've been working on the issue for months and are now nearing a solution. katharine da costa reports. horns blaring and out of control. the cruise ship ploughs into the dock, ramming a small tourist boat and sending dozens of people running for safety. on board, stunned passengers braced themselves for impact. someone else went in the water! back that way!

it was just a matter of shock, and we were trembling, we couldn't believe what we were seeing. and just to see this thing out of control was just, it was almost literally unbelievable. the collision happened this morning on the giudecca canal, one of the busiest in venice, adding to growing pressure for large ships to be banned. translation: this is yet another demonstration that it no longer make sense, it is no longer conceivable that these huge ships can pass through the giudecca canal. the ships owners, msc cruises, have blamed a technical issue and say they're helping the authorities with their investigation. katharine da costa, bbc news. sebastian fagarazzi is the co—founder of the website venezia autentica which focuses on tourism in venice.

he visited the site of the crash earlier today. we must recognise that we have been lucky because despite four people who were only lightly injured, so much worse could have happened. there was no loss of life, there was no damage to historical landmarks or the historical part of venice. there has been no fuel spill into the lagoon, into the waters of venice. so it's been good. but this must be our wake—up call. i believe that it is important to talk about this problem, because it's a problem in venice, but it's been a problem for two decades now, almost. so this time we have been extremely lucky and we must all sit down and discuss how it can change. the local government, so with the mayor, together with the national government of the italian state. a solution must be found because the way it is today, it's not ok and we cannot wait for something worse to happen before

we finally decide that a solution must be found. china has made a rare acknowledgement that the tiananmen square protests were violently put down. students and workers held a massive pro—democracy protest in beijing's tiananmen square in the spring of 1989. many were killed in a brutal clamp—down by the communist authorities. reporting on the event is heavily censored in china. defence minister wei fung—huh has told a regionalforum in singapore that stopping the "turbulence" was the "correct" policy. translation: everybody is concerned about tiananmen after 30 years. throughout the 30 years, china, under the communist party, has undergone many changes. do you think the government was wrong with the handling ofjune the 4th? there was a conclusion to that incident. that was political turmoil that the central government needed to quell. the government was decisive in stopping the turbulence, that was the correct policy. our asia pacific editor celia hatton put those comments

into context for us. wei fung—huh shows up and deals with the normal issues taiwan, he talks about the south china sea and then he's asked a question about tiananmen. and then he could have batted it away and simply moved on and he didn't. in fact, he took quite a defiant stance and he gave some comments, they were very unusual comments. you almost never hear chinese public figures speaking about what happened in 1989. so yes, he basically defended what the government did back then. he defended the crackdown. and said if china hadn't got rid of that turbulence then it wouldn't have enjoyed the stability and the development that it enjoys today. so quite a controversial stance, but in key, he didn't say anything about what actually happened back then. there are so many unanswered questions and details that we still don't know. let's take a look at some of the other stories making the news: pope francis has apologised

to the roma people for the roman catholic church's "mistreatment" of them. the pope chose to end his visit to romania in a mainly roma district of the town of blaj. in his address, he said the treament of roma communtities across europe showed catholics were "not stangers" to the "evil" of discrimination. scheduled presidential elections in algeria look like they won't now take place next month. the delay of elections has been one of the demands of the thousands of algerian protestors. they say they'll only accept a complete overhaul of the political system after the veteran president abdelazis bouteflika was forced to resign in april. the head of the german social democrats is resigning after the party's dismal performance in last month's european elections. andraya nahles said she no longer had the support she needed. the greens overtook the social democrats in the european vote, and opinion polls suggest the party has continued to haemorrhage support. the spd is the junior partner

in chancellor merkel‘s government a search for eight climbers missing on the himalayan mountain of nanda devi has been called off for the day because of bad weather. two indian air force helicopters had joined the operation on india's second highest mountain. yogita limaye reports. it is one of the toughest mountains in the world to climb. not many have dared to take on nanda devi's jagged peaks. this is a video filmed by a group of mountaineers a few years ago. now, in these icy slopes, eight climbers are missing. they were being led by martin moran, a man a well known in the climbing community. this is a photo of the team before they set out nearly three weeks ago. they were to return to the mountain's base camp on friday. when that didn't happen,

a search was launched. the terrain in the mountains is so treacherous, many parts are so remote, they cannot be accessed by road, that search and rescue operations are always difficult. once the climbers were reported missing, we are told two teams were dispatched from different directions to the base camp at manda devi to look for them. but even getting there and getting information out is a tough task. they were able to air lift these british climbers to safety. a group of four that was stuck on the mountain. unhurt, they are now aiding what the search efforts for the eight still missing. they were able to give us some input about the general direction in which these remaining mountaineers have gone. there seems to have been multiple avalanches in the area.

but as more time goes by, it becomes harder to find these climbers companions, the moran family has asked for the search to be continued and whiting. we're still holding a hope. you can get trapped and they might have to dig a hole and survive for a few days. but the monsoon is moving in now. it is very heavy rain in the indian lowlands and it is dumping fresh snow into the mountains. we are worried there is an avalanche involved. at sunrise, rescuers will once again begin to scour the slopes. group leader martin moran's friend for over two decades nigel vardy howjoins us from derbyshire here in the uk. thank you very much for speaking to us. thank you very much for speaking to us. every day that goes past now, it gets more serious? absolutely it does, yes. all the time that passes

brings more worry and more concern. obviously we hope they are all safe and well and somewhere up the mountain, but the longer the time passes, the more we worry. you yourself have been lost before in a similar situation, just what is that like? very, very frightening for the families at home. for us, we know it isa families at home. for us, we know it is a difficult situation but we are coping with it on the mountain. if you don't have communications to tell people we are safe and very sadly they are worried for our safe return. tell us a bit about martin, he is very experienced? extremely, one of the best guides i have ever worked with in my entire life. also a lovely family man. his entire family a lovely family man. his entire fa m ily love a lovely family man. his entire family love and work in the mountains, he is so competent and so good. that is why i am so hopeful something good will turn out of the

situation. from what i'm hearing he was an at finding new routes, is that what you think you would have been doing this time or can we just not know? the expedition was planned to go out to nanda devi and try and climba to go out to nanda devi and try and climb a new peak and on the new route. that was martin all over. he didn't like following the crowds of other people into areas that were overcrowded. he looked for what we might call old style, exploratory mountaineering where we can still go and find new places and peaks to climb. what are the kind of things that when you are lost, you have beenin that when you are lost, you have been in the situation, that people will need to be doing finding that shelter and sources of sustenance? depending on where they are in the base of camps, i don't know if the camp is above them or below them, if it is ina camp is above them or below them, if it is in a camp, then it is hunker down, wait for clearer weather or whatever to come back or be in a

position where you can descend safely. if you don't have that, dig a snow hole and get into some shelter. work with what you have got and wait it out. it is not an entertaining thing to do, but it means you can survive safely until you are in a position to descend or at least get some help. nigel, thank you very much for your thoughts. these are difficult days and hours of course and therefore we wish for a positive outcome. nigel, thank you. thank you. stay with us on bbc world news, still to come: preserving scotland's peat bogs — we meet some of the people looking after the landscapes that help regulate our climate. the queen and her husband began their royal progress to westminster. the moment of crowning, in accordance with the order

the latest headlines: a 13 storey cruise ship has collided with a quay in venice reigniting calls for a ban. china's defence minister has defended the crackdown on the 1989 tiananmen square protests in a rare public acknowledgement of events. china's defence minister has responded robustly to us claims that beijing is trying to expand further into the asia pacific region. speaking in singapore, wei fung—huh said china would not take an inch of land, but would not cede an inch of territory either. on trade talks with the us, the minister also said china is leaving the door open — but won't be bullied by the united states. from singapore, karishma vaswani reports — and a warning her report contains flash photography.

it has been almost a decade since china sent its defence minister to speak at this gathering at the who is who of the defence well. this year, beijing had a strong message on everything from trade to the south china sea, to taiwan. translation: as for the recent trade friction star by the us, if the us wa nts to friction star by the us, if the us wants to talk we will keep the door open. if they want to fight, we will fight until the end. the south china sea, a major shipping route with over 100,000 ships passing every year and over 100,000 ships passing every yearand a over 100,000 ships passing every year and a flash point between the us and china, was another area at the chinese minister address. beijing has built at military installations here and laid claim to all of it. the us has conducted naval operations in the waterways, prompting a warning from china this would destabilise the nation. but it was on taiwan and the ministry that

the minister struck the harshest own. translation: if anyone dares to split taiwan from china, the chinese military has no choice but to fight at all costs for national unity. hereby, i have a message for the dpp authorities and external forces. first, no attempts to split china shall succeed. second, foreign intervention in the taiwan question is doomed to fail. china's typical message at the sorts of gatherings is always consistent. we are not the instigators of instability, but if you are going to pick a fight, we are not going to back down. this year though, china's message has been much stronger, raising concerns amongst men here that the friction between the well‘s two superpowers is only likely to grow. olly foster has all the sport. hello and thanks forjoining us.

we saw one of the greatest shocks in the history of the heavweight division although former world champ anthonyjoshua has described his first professional defeat as a minor set back. he was beaten by andy ruinunior in new york. the mexican was a late replacement to facejoshua but knocked him down four times before the fight was stopped. a rematch is on the cards and joshua has vowed to get his three world titles back. ade adedoyin was at madison square garden. not many thought this would go the distance and even fewer thought it would be joshua who would be counted out. the champion struck first and, as he went for the finish, ruiz countered, wobbling joshua before a right hand sent him to the canvas. sensing his moment, ruiz swarmed onjoshua in the seventh. two more knock—downs and it was all over. the referee had seen enough. a shock to rank amongst the greatest in heavyweight history by a man who wasn't even supposed to be there.

i wanted to prove all the doubters wrong. there is telling me i was going to lose in the first round, the third round. what do you know man, iam the third round. what do you know man, i am the first mexican heavyweight champion of the world. joshua says he still wants to face the wbc champion deontay wilder, but more realistic is a rematch with ruiz. boxing is about not getting hit and i got hit one too many times. it's all good. it's not the result i wanted but it doesn't define me. i'm going to bounce back, sharpen my tools, sharpen my mindset, and i think there's still a lot of positives. there are still some huge fights out there for him. nothing changes. going into tonight, we didn't know what was coming next in november or december. now, ithink what was coming next in november or december. now, i think we do. this was meant to be the moment when anthonyjoshua conquered america, but rather than make his mark here he leaves america with questions now about his future.

there were straight—forward wins for roger federer and rafael nadal at the french open. but the 2015 champion stan wawrinka needed five sets and more than five hours to beat stefanos tsitsipas — the longest match of this year's tournament so far. he'll face federer in the quarter—finals. and johanna konta's fine form on clay continues — she beat donna vekic in straight sets to reach the quarterfinals the first british women to make it that far since jo durie back in 1983. she faces the american sloane stephens next. liverpool are back home from madrid and they have been parading the champions league trophy through the city streets. the 2—0 win against tottenham saw them became european champions for a sixth time. azi farni was following the players tens of thousands were expected, but hundreds of thousands have turned up. they are on the streets here, they are on wreaths, balconies, bus

stops and scaffolding, all to catch a glimpse of their champions league heroes. it's been a long time since the city has been able to celebrate like this, since the 2005 champions league parade and the 2006 fa cup array, there has been a long period of hope and expectation. that has now been fulfilled byjuergen klopp and bay—side. ask any of the fans here at the beginning of the season and they would have told you it would be a different trophy and they would have told you it would be a differen' waiting so long one they have been waiting so long for in the not—too—distant future. bangladesh pulled off a big shock at the cricket world cup, beating south africa

by 21 runs at the oval. shakib al hasan and mushfiqur rahim made a stand of 142, a world cup record for bangladesh, as they reached a one day record 330 for six. had south africa chased that down it would have been a tournament record but they fell short. they've now lost both their matches so far they lost to england in their opener and the hosts face pakistan at trent bridge. they've posted two world record scores at the ground since 2016. they beat pakistan 4—0 in their one day series last month but there won't be any complacency we prepare for pakistan at their best. we have certainly seen them more than two years ago, they were the best side in the world in the champion's trophy. they turned us over and turned india over. who were contenders for the champion's trophy, so we will be preparing the best we can for their a—game. should be a great atmosphere for that one at trent bridge. that's all the sport for now.

scientists are warning that drought could damage scotland's peat bogs, undermining efforts to tackle climate change. the flow country, in the far north of the nation, stores three times as much carbon as all the trees in the uk combined. now artists are trying to raise awareness of the area's importance by turning the scientific data being gathered there into music, sculpture and sound. this report from james cook. this is the flow country, a blustery bog that blankets 1,500 square miles. unique in europe, it looks flat and featureless. when you first walk out into this bog, you get the idea that there is nothing much going on here, but it is amazing what happens if you just stop and listen. suddenly the whole landscape seems to come alive. birds chirping.

bubbling sound. from this observation tower, scientists and visitors alike can marvel at a landscape formed over thousands of years. the peat is composed of not—quite—rotted—away remains of plants, and plants, when they are growing, take in carbon through photosynthesis, so that is holding carbon in the peat. and the sphagnum moss, that is the important one. that's the main builder of the peat. cathy hind keeps her ear close to the ground. she is capturing the sounds of the flow country for a show of soundscapes and sculptures at the edinburgh festival. she is one of five artists who are turning science into art. i started off recording sounds from inside the bog, i have underwater microphones that i can throw into the bog pools and have a listen.

i also have microphones i can bury in the squelchy bog. i kind of want to listen underneath the bog, below the blanket, which is the title of the show, and i am hoping to hear some other water boatmen and other invertebrates that will make popping sounds. the art carries a message about conservation in an era of climate change. for centuries, the folk of the highlands sliced and burned peat for warmth. scientists now say it is essential to keep the bog pristine. underneath our feet in the flow country there is an estimated 400 million tonnes of carbon. that is more carbon than trees in the whole of the uk, approximately three times as much. peatland covers overall a very small proportion of the landmass of the globe, but they play a tremendous role in regulating and slowly but surely cooling the climate. is there a danger that

as the climate warms, that the storage of carbon he will be disrupted? there is a risk. when peatlands are disturbed we lose the carbon at a much greater rate than it is being created, so it could fuel climate change rather than mitigated. rather than mitigate it. conservationists are fighting back, damming drains to raise the water level and clearing 1980s forestry to restore the peatland to its original state. preventing this bog drying out is, they say, critical in the struggle against climate change. james cook, bbc news. a reminder of our top story. the italian environment minister has said the government is ready to ban large cruise ships from the giudecca canal in venice. his comments came after a huge cruise ship lost control as it tried to dock in venice.

don't forget you can get in touch with me and some of the team on twitter — i'm @lvaughanjones. the weather headlines might be made by the fact we have just experienced the warmest day of the year so far with over 28 degrees in norfolk, but elsewhere there was quite a bit of cloud around and they may not have completed the player clifton in north yorkshire and that is because this trailing portion of a weather front has gradually worked away from west to east across many parts of the country. we are not done with it yet because the parent low will sit close to western scotland in the early hours and the thick cloud will keep their showers coming for northern and western parts of scotla nd northern and western parts of scotland and northern ireland

overnight. it will be fresher across parts of the uk than last night and some of the temperature didn't get below the mid—teens. that front continues into the near continent and then it is the low pressure that dominates. a few isobars on the chart so the wind will be a factor, especially across the northern part of the british as. monday, not a bad day from the low centre, you can see the steady flow of showers in northern and western parts of scotla nd northern and western parts of scotland and into the central belt and northern ireland. but across england and wales it will be a decent sort of day. quite a breezy one. you have to add in the gusts, which some of them close to the centre will give gusts of up to 40 01’ centre will give gusts of up to 40 or 50 miles centre will give gusts of up to 40 or50 miles an centre will give gusts of up to 40 or 50 miles an hour or so. temperatures, nowhere near the 28 maximum on the day will be around 20 01’ maximum on the day will be around 20 or21. on maximum on the day will be around 20 or 21. on tuesday, another set of weather fronts drifting from south and north across the british isles. if you are looking for rain across

eastern parts, it may be the second half of the week. if this comes true, and waving portion of the front may drag sufficient cloud into the eastern side of britain to give some significant rain at last, at last. you get a sense from looking at the capitals, the forthcoming week will be unsettled with a temperature for the most part locked rigidly from any part in the teens. the forthcoming week, with low pressure dominating, it looks to be u nsettled. pressure dominating, it looks to be unsettled. there will be sunshine at times but unwelcome rain for some. overall, it will be a bit cooler.
