hello, this is bbc news. the headlines... president biden promises the federal government will safeguard womens�* rights to travel within the us to get an abortion. the extremist governors try to block a woman from travelling to his state and prohibits herfrom seeking medical help she needs, to a state that provide that care, the federal government will act to protect her bedrock rights. ukraine wants turkey to detain a russian—flagged ship which it says is carrying stolen grain. french airport workers strike over pay and conditions, leaving holidaymakers stranded as flights are cancelled. and adele — performing herfirst public concert in five years — leaves her sell—out crowd at london's hyde park delighted. a vigil will be held in east london today in memory of zara aleena — the 35—year—old solicitor who was killed while she walked home

from a night out last weekend. zara's friends, family and anyone who wishes to join the event will walk in silence along the same route which she took. a 29—year—old man has been charged with her murder. celestina olulode has more. zara aleena, described by her family as insightful, empathetic, independent and fearless. she had a really big heart. and so she would very easily connect with people's pain, very easily connect with their need. and she was always the bigger person. "i'll help you. "i'll sort that out." her mother's only child, the 35—year—old, was at the start of her legal career when her life ended suddenly. last weekend, she was attacked on her way home in ilford, east london.

zara's aunt farah says she's speaking out to protect the rights of all women. this is the most horrific experience that we've had as a family, we've experienced something that zara experienced. and there's nothing that can change that for us. but there is something that we can do, and that is to say that this shouldn't have happened. she shouldn't have had her entitlement to walk home taken away. zara's family have invited friends, loved ones and those affected to walk the ten minute journey home from where she was attacked. we'll never get through this. but it will help us... ..somehow, in some way it will help us.

celestina olulode, bbc news. now on bbc news, it's time for the travel show. this week on the show... i am in mexico to discover how a river cleanup is getting on, and meet this little local. this is so incredible! simon is here with tips on how to carry on travelling despite the cost of living crisis. i'm travelling by train through germany, on what i regard as the best rail deal ever. and a day trip to a thai prison anyone?

this week i am in mexico city, in the wetlands, one of the country's must see destinations. this sprawling network of canals was first built by the aztecs and stretches over 180 kilometres. not surprisingly, the area now attracts masses of tourists every year. look at all of these amazing boats. they are so incredible. these are incredible. i am here to meet carlos diaz, one of the best tour guides in town. but this isn't your typical sedate trip along the river.

i was honestly expecting to go on a quiet little boat ride, but this place is a real siesta. —— fiesta. we are stuck in a trafficjam of like ten different boats. tourist boats, shop boats... floating band boats. there is a mariachi band! this is unreal. singing in spanish. applause.

away from the joyful chaos, i want to talk to carlos about life on the canals. that's if i can keep us dry, of course! how important is tourism to xochimilco? how has the area changed in that time?

i mean, having grown up here in this area, how do you feel when you notice all these changes? but the problem is much bigger thanjust tourism. these wetlands are the lungs of mexico city, and provide the capital with around a third of its drinking water and a huge amount of food. professor rodriguez vasquez has been monitoring the solution, and it is pretty plain to see why this situation is getting worse. —— this pollution. this isn't the most beautiful spot in mexico city, is it? yeah. can you tell us how badly the water

is contaminated here? it is very highly contaminated with pathogens, chemicals, pesticides, hormones and human waste also. yeah. and here we have a lot of places like this. so this is not the only drain like this in mexico city. no, no, we have a lot around. not only does this pollution contaminate the water, but the dangerous pathogens can also evaporate into the air and be absorbed into the crops that are grown in the wetlands. you know, the moment you leave behind the super busy embarcaderos of xochimilco, it feels like you enter a completely different world. there is so much wildlife here, so much greenery, it is so serene. but even out here in the more remote areas of the wetlands, the pollution is endangering one

of mexico's most iconic animals. the strange looking but much loved axolotl. what is so special about these little creatures? i can't believe this is happening. i'm about to hold an axolotl! it is so smooth, it is like holding a baby! the axolotl is not only endemic

to mexico, its population is limited to these wetlands. and the worsening pollution is threatening its very survival. this is the most incredible thing i have ever done in my life. 0k, put him back! thankfully the conservation project armando runs here has been a great success, and as a result acro numbers are now increasing across the wetlands. —— axolotl numbers. armando�*s work is brilliant, but to fully restore the area to its former glory, ultimately the pollution needs to be tackled.

luckily my friend professor rodriguez vasquez may just have identified a simple but effective solution. in a rather basic looking lab in the wetlands, her team have invented a system that produces tiny bubbles called nano bubbles, which can be pumped into the polluted water. how does the science behind this actually work? yeah. we create the nano bubbles with solar energy, so these nano bubbles can attack or can destroy the contaminants. as well as tackling the pollution, these nano bubbles also help to oxygenate the water my breathing life again into the waterways. honestly your lab looks, everything here looks pretty simple. it is very simple. it is very cheap, and also easy to manage. that is the best kind of technology, right? when it is simple, straightforward, accessible and sustainable. exactly, sustainable.

and what is even more encouraging is that this simple but effective technology can be used on trajineras so the tourist boats can be a part of the solution in the fight against pollution. that's the button that starts it off? all right, let's do it! ready? yeah. you can see the nano bubbles. oh, it's working! that's so cool! it's amazing to think that this piece of tech is actually cleaning the canals as we speak. amazing, hey?

what these projects across the wetlands hopefully show is that with a bit of creativity and collaboration, tourists can play a key role in helping to maintain stunning places like this. and that's got to be good news. and if you're planning a trip here anytime soon, here's a few things to think about. in western mexico the world's largest gathering of mariachi bands will come together on 30 august to kick off a two—week festival dedicated to the country's most traditional folk music. the celebration will begin with a huge parade through the city of guadalajara where mariachi bands from as far away as japan will all play together. you can expect workshops, lectures and plenty of inescapable impromptu performances throughout the city for the duration of the festival.

if you prefer the calm of the ocean, why not explore the second largest barrier reef in the world? the mesoamerican barrier reef runs along the caribbean coastline of the yucatan peninsula and is home to 66 species of coral, several hundred species of fish, as well as sea turtles, dolphins and whale sharks. remember though, reef environments are fragile to human impact, so be sure to dive with a responsible provider. for six days from 14 october, some of the world's finest classic cars will be covering a route over 600 kilometres at la carrera panamericana. it used to be dubbed the most dangerous, but safety standards have come a long way in recent years.

and of course if you are in mexico on the first and 2nd of november than you won't be able to avoid one of the country's guest event. —— biggest events. more commonly known as the day of the dead, the national holiday honours the deceased and many believe that on this day, the border between the spirit world and the real world dissolves, and so relatives often spend the night by the graves of their loved ones. stay with us, because still to come... simon has some cost—saving travel tips. if you are flying, then try to travel with cabin baggage only. and thailand opens its prison doors to tourists. so don't go away. hello and welcome to

this month's guide. well, summer is here and many of us are desperate to get away. but with rising costs and tricky travelling, the prospect can be offputting. after some scenes of airport chaos, airlines have trimmed millions of seats from their planned summer schedules, causing fares on some popular routes to soar. so, consider going by sea. britain has excellent ferry links to france, spain, the netherlands and ireland. there is loads of capacity this summer and you can get some really good rail sale deals. such as about £40 one way from many british stations to ireland. and you get a generous baggage allowance. if you are flying, then try to travel with cabin baggage only. i managed just with this, and it meets all known airline rules. you won't need to queue up

to check—in, there is no chance of your bag being sent to the far side of the earth and no need to wait around at the carousel at the far end when you should be beginning your adventure. best of all, you'll save cash. and choose your day of travel carefully. for holiday flights, saturday and sunday are in strongest demand with friday and monday also busy. tuesday and wednesday are likely to see the lowest fares and the thinnest crowds. many viewers have been in touch about car rental rates. yes, they are higher than ever this summer. during the pandemic, many car rental firms sold off their fleets and now they cannot get enough vehicles to match demand. so, choose somewhere with excellent public transport to stretch your holiday budget. along spain's costa blanca and costa del sol, as well as the portuguese algarve, there are excellent coastal railways.

with frequent trains and subsidised fares, making them excellent value. almost anywhere in asia, from eastern turkey to singapore, public transport is cheaper, more reliable and safer than self—drive. choose the train when you can, such as the amazing line through uzbekistan, paralleling the silk road from bukhara to samarkand and on to the capital tashkent. if you are on the road, simply choose the highest category of coach you can afford. america is in love with the highway but increasingly, the cities have reliable public transport connections such as the bright line from miami via fort lauderdale and soon opening all the way to orlando. and long—distance buses are making a comeback with one firm promising a private jet experience on the four—hour run from washington

to new york city. this summer, i'm travelling by train through germany on what i regard as the best rail deal ever. in the entire month ofjuly or august, you payjust nine euros for a ticket taking you anywhere in the country on all but the fastest trains. the ticket is also valid on city transport, meaning you can experience the amazing dangling tram of wuppertal, the closest public transport gets to a theme park ride. stretch your holiday the furthest, though, swap the med for the baltic beaches of eastern europe. a trip to the coast of poland, lithuania, latvia or estonia is surprisingly affordable. and the black sea coastline

of romania and bulgaria also offer outstanding value. going west, canada is significantly cheaper than the us, though in both nations, remember, you are now expected to tip 20%. for further fun adventures, wait until later in the year for tropical sun at affordable prices. two favourites of mine are the beaches and heritage of kerala in southern india and the longtime backpacker favourite vietnam. airfares in november in the uk are barely half what they are in peak summer. well, i hope some of those ideas have stimulated your travel appetite. whether you are hoping to warm up or cool off this summer, where there is a will, there is a way. good luck. thanks, simon! 0k, next up, we're off to thailand where the government is slowly turning some of its prisons into tourist attractions. wyong central prison,

close to the capital bangkok, has been one of the first to open and we've been given special permission to go along and film there to check out what tourists can expect to see. —— rayong.

previously, prisons were treated as no—go areas. they are usually overcrowded and i think the department of corrections wants to be seen as joining a wider coalition of government agencies, encouraging tourism, encouraging people to come back to thailand. they are certainly going to have to somehow improve conditions in some ways and at least on the surface. but the question is whether anything really changes.

well, that's it for this week. but, coming up next time... we're in sydney as its most iconic landmark celebrates its 90th birthday. never gets old. this is amazing. and we hear about its role in bridging the gap between australia's different communities. more australians are supporting that the aboriginal flag sits at the top of the sydney harbour bridge. if you cannot wait for that, check us out on social media. such bbc travel show on facebook and instagram and look for the little blue logo. —— search. but from now, from the chaos of mexico, safe travels and i will see you very soon. bye— bye.

hello. there will be some decent sunny spells out there for a fair few of us at times this weekend, but always be on the lookout for skies darkening, showers will never be too far away from the forecast throughout this weekend, and there will be a cool breeze to go with it. temperatures down a little bit than we would normally expect at this stage injuly. the bulk of the day's rain is linked to this weather system here, it is linking across scotland at the moment, to the far north and north—west, this is where we will continue to see the more persistent rain. this one here, drifting through the midlands in the direction of east anglia, south east, producing showery bursts of rain, eventually reaching east anglia, south east into the evening, but the bulk of the day remains dry. where we started with cloud and rain in northern ireland, southern scotland, northern england, wales, and including the north and west midlands, things will turn dry and bright with more sunshine through the afternoon. still one or two showers, a bit of a keen breeze coming in from the south—west, and in those cloudier moments that will make it feel a touch of the cool side.

16—19 degrees, below par, but we could still get around 20—21, east anglia, south east. but this evening there will be a few showers pushing through, not everyone will see them, though, and into the night many will become dry again. further outbreaks of rain in the far north of scotland and then a few showers developing in the west later on in the night. temperatures as we start your sunday morning, very similar to where this morning started, 9—12 celsius. into sunday we go, a dry and bright start for the vast majority, always a bit cloudy across some of these western districts. a few showers around here as we start the day. those showers, though, as the westerly wind kicks in, will track their way eastwards, and so through the afternoon it is eastern areas most prone to some showers, the odd heavy one across eastern parts of northern england especially. that means fewer showers in the west, a brighter end to the day with a lot more sunshine around. because there are big gaps between the showers, some of you will stay completely dry throughout and it will feel a touch warmer than today, temperatures up a degree or so for most parts of the country. then as we go into the rest of next week, we will see high pressure gradually and slowly build in from the west,

but around the top end of it we will start to bring a lot of cloud in off the atlantic. that high pressure not fully with us until we head in towards next weekend. so it does mean in the outlook across the northern half of the uk, plenty of cloud around, some drizzle around coasts and hills, there will be a few brighter breaks here and there which will lift and temperatures every now and again, whereas the further south and east you, this is where we will see the best of the sunshine, lightest of the winds as we go through the week, and it is here where temperatures by the end of the week could be into the mid 20s.
