our main story on bbc news: a major anti—terror operation is underway in paris, after a gunman opened fire on a police bus, killing one officer and seriously wounding two others. the attacker, who targeted the busy champs elysees in the heart of the city, attempted to flee the scene, but was shot dead by police. officials have confirmed he was known to the intelligence services, and a police search is under way at his home near the capital. the islamic state group says it carried out the shooting, naming the attacker as a belgian, abu yousif. french president francois hollande has held crisis talks with his prime minister and interior minister, and is set to convene his security cabinet on friday morning. the incident comesjust days ahead of the first round of the french presidential election. some of the candidates have suspended their campaigns in light of the attack. the labour leader, jeremy corbyn, has used his first major speech of the election campaign to pledge that he will put power and wealth

in the hands of the people if he becomes prime minister. he presented himself as the anti—establishment candidate, taking on what he called a system rigged against working people, and he told his supporters that the outcome of the snap election was not a foregone conclusion. meanwhile, the prime minister has restated her commitment to cutting annual net migration to a sustainable level, in the tens of thousands. here is our political editor laura kuenssberg. no—one is going to say they are all the same, not in this election. and not the admirers of the labour leader, who queue round the block to hear him. we need something different, not more of the same. i really enjoy seeing him speak. this is a man who should be leading the country, and should be our prime minister, because he's offering a real alternative. the left waited a long time for a leader likejeremy corbyn, but will the rest of

the country rush towards him? he is their star. but what about you? the labour party that's standing up for working people, to improve the lives of all. it's the establishment versus the people. it's our historic duty to make sure the people prevail. applause. in practice, that means hikes to the minimum wage, bigger benefits for carers, higher taxes for some of the biggest businesses, who he said proudly should fear him. if i was southern rail, or if i were philip green, i'd be worried about a labour government, i really would. if i were mike ashley, or the ceo of a tax—avoiding multinational corporation i'd want to see a tory victory, i really would. why? because those are the people who are monopolising the wealth that should be shared by each and every

one of us in the whole country. but it means more borrowing and spending, too, ideas that at the last election didn't do labour many favours. what is it you hope to show to voters in the next seven weeks beyond this room, that they haven't seen in the last two years since you've been party leader? our message is one of inclusion and socialjustice, and we're going to get that message out across the whole country, and i'm very confident of that. this invited audience of loyalists leapt to their feet. this was a classicjeremy corbyn speech, the kind of speech that won him the labour leadership election. he spelt out in sky—high letters how he will pitch this campaign. the people versus the powerful. he's obviously a man of principle, he's a man of integrity. we know that for a fact.

can he step up to the plate, and the next level? well, he's got 50 days now to do that. i'm really impressed. jeremy has always said the right thing, he'sjust never had the opportunity. he's a decent man. maybe decent people don't get elected, but he's also got an allotment, he makes his own jam, did you know that? i did know that. there you go now. beyond the home crowd in seats like luton, willjeremy corbyn and his team's campaign of us and then cut through? i'd love to see him again in power. he hasn't got the oomph. he's a modern socialist, and i think if given the chance he'll make changes. i don't think he's a coherent leader. and i've voted labour in the past. i'd never vote for him. inevitably, the prime minister claims mr corbyn is not up to it. not least because, unlike the tories, he won't commit as she affirmed today, to the tory ambition to cut immigration to under 100,000.

no mention of the fact the target has been missed for years. this election is about ensuring that we have strong and stable leadership in this country, in the national interest. it's about strengthening our negotiating hand for brexit, and about sticking to our plan for a stronger britain, developing a more secure future for ordinary working people in this country. jeremy corbyn is a happy campaigner, comfortable with his fans. but he needs millions more. a brutal election beckons. now on bbc news, the travel show. coming up on this week's travel show: we continue our journey through thailand... 0oh! you've got a big nose. ..as i head to the world's first ever elephant hospital. good? she's been eating her greens. haven't you? we're in the big apple to meet the man who's travelling the world without leaving new york. hands up, eyes wide open. you don't want to miss it. and rajan heads to spain to take a ride on europe's newest, fastest and tallest roller—coaster.

this week, i'm in northern thailand. it's mountainous landscape and lush jungles are an ideal environment for the asian elephant. the animal is seen as the symbol of thailand, and around 3000 live in these wild forests. the country also has a captive elephant population of almost 4000. controversially, some of them work in the tourist industry. caring for all of these elephants is a hugejob, particularly if the animal needs specialist medical attention. i've come to lampang to meet some of the vets who are attempting this mammoth task. when it was opened in 1993, this was the world's

first elephant hospital. and since then, they've treated over 4000 elephants. i'm here to meet some of them. the hospital aims to provide care for any sick or injured elephant in thailand. what kind of patients do you have? we have all kinds of illnesses, sicknesses, knife wounds, gunshot wounds. some have diarrhoea, constipation, cataracts. some have serious cancer, and tumours. the most difficult case, the victims of landmines. good morning. morning. how are you? i'm fine. good to see you. dr kay takes me to meet some of her patients on her morning round. hello! lots of adults. wow! so in the morning, you have to go and check up on the elephants themselves?

yes, every morning. wow. she is huge! yes. what's her name? her name motala. motala? yes. she about 57 years old. and what happened to her foot? she stepped on landmine in burma. and after that, the owner bring motala here, and donate here. so she's one of the permanent residents? yes. the hospital has five permanent residents who need round—the—clock care. the rest of the patients have been brought here by their owners for shorter term medical treatment and operations. for motala, each day starts with her prosthetic leg being fitted, so she can walk out for breakfast. well, so this is the prosthetic leg, can i see it? whoa, so big!

it weighs a good, at least, 15 kilograms. very heavy indeed. so herfoot will go in here. and these are all formed specifically for the elephants themselves, so they're all different. they're just putting some talcum powder to help with the dryness, and of course, the comfort. a layer of talcum powder on the inside as well. in the early morning and late afternoon, when the sun isn't too hot, motala will walk out for a fewer hours. there you go. it's on. motala walk along. adult females weigh just under three tonnes on average. she's coming to get her breakfast. so the prosthetic is needed to give vital relief to her other three legs, which are under enormous pressure. how long did it take her to get used to the prosthetic leg? five to seven days.

then she gets used to it? yes. so quick learners. she put quite a lot of weight on that. checking over the elephants each day is part of the hospital routine. wow. this one's a little bit smaller. hey! mosha was also injured bya landmine, and came here when she was just seven months old. she's now 11. hi. 0oh! you've got a big nose! and what are you looking for? she had the wound inside. dr kay has cared for her since the day she arrived. are you smiling at me? mosha is good.

healthy? yes. she's been eating her greens. haven't you! very friendly. this one belongs to motala, the older one. and that's mosha. because she's growing up. she's still young. that's true, so every so often you have to get a new one. getting taller. that's right. softer inside. soraida started the hospital after seeing elephants die because there was no way to treat them. so i told myself, ok, that's it. if no one is going to do it, i'm going to do it myself. there should be a place where elephants can be treated, because there's no elephant hospital. the hospital is funded by donations and treatment is provided for free. the procedures are similar to what you'd see in

a human hospital... finished. that was quick. ..except on a giant scale. this elephant bunce has a stomach problem. so needs an iv drip to make sure she gets all the vitamins she needs. dealing with the elephant being so high, they've had to get this platform up here. and the iv drip goes all the way up to the top there. it uses that gravity to push the medicine through the pipes. so one of the only soft spots of the elephant is actually on the ear, orjust behind the ear. so the iv drip will go right there. after medicine, get treaties! tourists can come here to see the elephants in their recuperation

areas, but there are none of the shows and rides you might find at elephant camps elsewhere in thailand. some have called for a ban on using these revered animals in the tourist industry, but soraida tells me that could also create problems. to ban them, then we have to have the solution, then where would these elephants be? you can't take 4500 elephants back into the wild. how are we going to keep them in natural surroundings and in a way to earn some money in order to treat them well? she's calling for a new law to protect thailand's huge elephant population. they use the elephants for riding, under hot sun, on hot country roads, all day long. some camps don't even have shades for the elephants. so i'm asking the government to please set the rules.

if they really prefer to have the riding, would it be like five minutes right? do you feed them along the way when they get hungry? if they stop, they shouldn't be eating them to walk. things like that. the focus here is on working with elephant owners in the community to help any animal that needs medical attention. a baby. they also have a nursery section, and i'm fortunate enough to be able to see a newborn. this is definitely something special. hello! hello, mamma! so how old is the baby? nine days. nine days, it is nine days. what's the baby's name? his name mina.

mina. yes. wow, so small. these, i recognise, are banana flowers, and dr kay tells me that they feed the mum banana flowers, because it helps to produce milk, giving her vitamins and minerals. and she was just suckling. there she is. look. hello, curious one. oh, my god. her trunk is so small. it's humbling to see the connection dr kay has with these animals as she gives baby mina a checkup. it's amazing to see elephants like these that would otherwise have died in the wild, actually thrive here in the hospital. spending time with dr kay,

and soraida, and learning the ins and outs of what goes on here has been an absolutely amazing experience that i won't forget any time soon. and if you want to see more of the elephant sanctuary, keep watching until the end of the show, and we'll tell you when you can see our special 360 degree film of the amazing work going on there. well, stay with us, because coming up... shall we have a quick go, then? yeah, let's go for it. let's do it. rajan heads to spain to test drive your‘s fastest ever roller—coaster. rajan heads to spain to test drive europe's fastest ever roller—coaster. and we meet the native new yorker who's eating his way around the world without leaving the big apple. so right now, i'm at country number 156. it's time now for trending travel, your monthly mash up of the best

travel—related stories, snaps and videos online. first up, across the world in 170 dishes. charles bibilos is attempting to eat one mealfrom every country with over1 million inhabitants. but there's a catch... he can't leave new york city. so you can get to about 90 countries by eating in restaurants in new york city. so that means about 80 have to come from a community event, or a fundraiser, a trip to a mosque or a church, or a home—cooked meal. so right now, i'm at country number 156, so i'm looking for 14 more meals. and his most unexpected culinary discovery? charles has developed a taste for namibian caterpillars. i absolutely love them. they kind of taste like a fried mushroom. next time you're struggling to find a wi—fi connection, considered climbing 5000 metres to everest base camp.

that's where the nepalese government plan to install free wi—fi. it's largely to help rescue teams communicate in emergencies, but will be open to intrepid bloggers, tweeters and instagrammers, too. in south africa, a team has come up with a new way to combat rhino poaching. the sigfox foundation has inserted gps trackers into the horns of ten wild rhinos. it's estimated there are fewer than 27,000 rhinos left worldwide. by learning more about their movements and behaviour, the foundation hopes to find new ways of deterring hunters. and nervous flyers might be comforted by lilou, san francisco's first therapy pig. other breeds of therapy animal can be found in airports all across the usa, but lilou is a member of san fran‘s wag brigade. their mission: to patrol

the terminals and take some of the stress out of travel. thanks to everyone who sent us their pictures using the hashtag, #traveltuesday. here are some of my favourites. agata was drawn to venice out of season when she took this picture. and hjadal was in iceland when he took these shots of the snafellsjokull glacier. now let's look at the travel videos clocking up the views on line. meet telma and thomas, thomas is profoundly deaf, and together as blank canvas voyage, they meet deaf communities from around the world. every country we visit has different sign languages. for instance, hong kong and macau each have their own. we didn't understand each other at first, but we ended up communicating well through international sign. these people are generous,

kind, funny, beautiful. plan yourjourney, save money, buy a ticket and go. experience what the world has to offer. and if you see anything you think we should know about, don't forget to get in touch, it's @bbctravelshow. well, to end this week, 2017 marks 200 years since the first ever roller—coaster was opened in paris. since then, technology has made them faster, higher, longer, and of course, scarier. rajan has volunteered to try out the latest ride in spain's fuerteve ntu ra.

it's been a regularfixture on the costa dorado since 1995 as part of the biggest family resort in southern europe. fuerteventura is a well—established theme park, spain's biggest in fact. and they get about 4 million visitors here a year. but now they're building something that they say will take it to a different level, and that will give us one of the most amazing experiences in the world. i've come to ferrari land, licensed by the famous car brand, just as the finishing touches are being put to the site days before the launch. there are 11 rides here in total, but one in particular is hogging the limelight as the main attraction. a velocity accelerator ride called red force. two years in the making, it's now europe's tallest and fastest ever roller—coaster. 112 metres tall and a speed of 180 kph.

that's zero to 180 in five seconds flat. it is an attraction where the sensation is similar to formula 1. we thought about the roller—coaster to have the g—forces in acceleration, and also to make something, let's say, strong. i've got to admit, it was slightly unnerving to see the ride still being tested behind luiz as we talked. and then i found out, i was to be the first member of the public ever to try out red force. a human crash test dummy, without the crash bit, of course. how much testing goes on before it is open to the public? around 6000. times? cycles. 6000 cycles? 0k. thankfully, i have this veteran of nearly 1300 different roller—coasters in 21 different countries as company. what i love now, it's

the thrill of the chase. it's finding those coasters that are in obscure places, i go off to places like china, to find something different that you haven't done before and other people haven't gone to. i went to dubai recently, and i did 25 theme parks in six days. this is more than your average hobby. marcus spends up to two months a year in theme parks in chase of thrills. and now advises on how to maximise roller—coaster excitement. there's a whole absolute escapism. forget every stress of normal, daily life, and you're letting a machine like this take control of your destiny. it's a particular kind of pleasure, though, isn't it? because it's a short, sharp burst of real. now, is there an addictive element to this? i would say it's totally addictive. so it's back to the launch area to get a dose of this legal high.

and some last minute advice from the expert. put your head to there. back, yeah? yeah, that's it. and keep my eyes open? if you can open this, yes. 0k... i can't guarantee that. shall we go for it, then? yeah, yeah, yeah, let's go for it. let's do it. i was going to get the best views from the front. you feel the force on your face as well. right. there's a loose bolt there, should that be... hands up, eyes wide open. you don't want to miss it. ok, i'll try my best. i'll try my best. see if you can tell the difference... here we go. ..between the seasoned coaster and the rookie tv presenter. now, i knew you wouldn't be able to. incredible.

what the hell! whoa! tears going down my face, that was intense. mind blowing! there are moments when you think, this thing has lost control, and you are going to be swung out of it at any time. the g—force before you arrive just at the bit where it goes vertical is incredible. and yes, i actually must admit i feared for my life. i guess that's the point of this right, that you are genuinely scared out of your wits.

and i was. it was definitely thumbs up from the expert. this is definitely a top ten coaster. high—intensity, the height, itjust has everything going for it to make it an extraordinary coaster. i want to go again! that's all the time we have for this week, but coming up on next week's travel show: krista heads to the mountains of palencia in northern spain for a spot of wolf watching. i suppose, if it's the most elusive animal of prey in the world, it's probably not surprisingly don't get it on the very first try. and head to our facebook page and you can see a special 360 look
