invaded, and witnessed the devastation in the city of kharkiv, as intense fighting continues in the region. now on bbc news — our world. six million people have fled ukraine, half of whom have gone to next door poland. during a week in april, our world follows warsaw's mayor rafal traskowski. on the 24th of february, russian president vladimir putin ordered a military invasion of neighbouring ukraine. reporter: russian troops i are closing in on the capital, and in the last few hours multiple exposures have been reported. —— multiple explosions. the invasion trigger the largest refugee crisis in europe since the second world war. almost six million ukrainians have fled the country. reporter: more than half of those

who have left are now in poland - where local people are providing accommodation, food and other support. reporter: the population | of warsaw is nearly at nearly 20% in just two weeks. the mayor saying they can't handle the millions more that are expected to come here into poland. we are at capacity, we cannot accept another wave of hundreds of thousands of refugees in just one city, alone. we spent time with the city's mayor, rafal trzaskowski, as well as refugees and volunteers living through the crisis. i need to help the refugees in this tragic situation, but we need a system. we cannot do it alone, we cannot improvise any more.

the mayor had invited a group of local and geo leaders to his office to discuss the city's response to the influx of refugees.

just a month ago, five weeks ago, poland was 120th when it came to countries supporting refugees, now we are the second in the world, and we might become the first in the world. warsaw is overwhelmed, we have more than 300,000 ukrainians in warsaw alone, and over 600,000 passed through my city, a city of two million. there are no refugees on the streets of polish cities because they're in our homes. people simply opened their hearts and opened their homes to our ukrainian friends. since the war began, zofia has been co—ordinating

housing for refugees. her parents have opened up their home to a ukrainian family. it's a mix of polish and russian because i don't speak russian but i am trying to learn. they have been staying with my parents for two weeks and a half. they're from kharkiv, so kind of one of the worst places you can come from. they are less and less housing opportunities and more and more people coming, and also more and more people coming who don't know what's next. it's impossible to find apartments for larger families these days,

which are affordable for ukrainians. and, yeah, they have no idea what to do here, how to — where to send their children to school, what work they can do, you know? but, ukrainians are very much like poles, and since we're so close culturally, linguistically and historically, it's so much easier for them to start a life in poland quite quickly. of course, you know, with its challenges and with its tragedy of the whole situation but, i mean, i think it is doable in poland, at least for now. i don't know about the long—term. it's probably going to be a challenge. first day of the invasion, second day of the invasion, we saw those incredible crowds. most of those people, for the first few days, they were taking care of by their families and by their friends. but, then it changed. in a few days there were 30—40,000

people asking for accommodation, and so on, and so of course the reality was slowly sinking in. we started adapting our own city facilities in order to be ready for the numbers that were coming through the border because, i mean, we knew this was going to be a crisis of a huge magnitude. every corner of warsaw has had to be adapted to house the city's new guests. in the centre of town, a high school is accommodating 22 ukrainian refugees in one of its unused buildings. single mother vera and her daughter, eva, arrived here three weeks ago from the city of volodymyr—volynskyi in the west of ukraine.

the school has said that vera and her daughter can but, across town, the burden for providing for refugees are starting to show. —— can stay for as long as they need. 0n the second day of the war, polish engineer rafaljoined the small army of volunteers to co—ordinate deliveries of aid across the border to ukraine. with rafal�*s paid work on hold, his full—time aid operation is rapidly eating into his savings. how long can you continue doing this?

now we drive. rafal and his friends have created an orphanage in a disused country house near warsaw. it now hosts 16 children and three carers from central ukraine.

this is incredible that there are no pitched tents in parks, or there are no huge reception centres, because those people are with us, but of course it took an enormous effort of the society.

without the volunteers, the system would have broken down long, long ago. i, as the mayor of the city, i have a responsibility, i need to help the refugees in this tragic situation, but i also need to make sure that this city functions properly, because if it doesn't, then this incredible solidarity and energy of the polish people might be sapped. when the city services are going to be overwhelmed, people are going to start complaining, that's normal. in ukraine, vera worked as a masseuse. and although she has some savings from her business, she has started to work in warsaw.

like hundreds of thousands of ukrainian refugees in warsaw, vera is starting to confront the reality that she may not be going home any time soon. we have guaranteed ukrainians a citizen—like status, they have access to free education, to free healthcare and social policy. so now, the biggest problems are the problems of long term. most of these people are going to stay with us for months or years. there are thousands of ukrainian refugees looking for accommodation in warsaw, so the mayor is taking a major step to reclaim russian owned property which can then be used to house refugees. that is the property of the russian embassy, it is called a spy building, in warsaw, because that is where most of the russian diplomats were housed for years. this building is in a very bad state, but the idea is to give it to the ukrainian refugees.

it is symbolic. we sometimes need symbols, and of course this building should also serve the ukrainian community in warsaw, i hope as soon as possible. the mayor was meeting with the ukrainian ambassador to formally claim ownership of the building.

the russians are preparing for an offensive in the east and in the south, and there are seven million displaced ukrainians in ukraine. so whatever happens, if there is an escalation, we might expect another million crossing the polish—ukrainian border. and of course we are at capacity, so that is worrying. so there is a second wave, we will keep on helping, but the conditions will deteriorate, and then we will have to create reception centre or camps for refugees, because we are at the limit. we need to share that responsibility with our friends in europe and elsewhere, because we cannot simply carry the burden alone. the mayor has asked the eu to come up with a relocation scheme, in a bid to ease the pressure on cities like warsaw. in the meantime, vera and millions like her will remain in poland until the ukrainian president says

it is safe to return.

hello again. well, cloud certainly built up on sunday to bring some scattered showers. the heaviest showers were focused across parts of wales and southwest england. the sky certainly looking threatening on the horizon here around the gower in south wales and that's where we had this line of heavier showers pushing in across wales and into southwest england. there were quite a few for scotland and across northern and eastern areas of england, as well. but we look at the forecast now for monday. this area of low pressure moves westwards from scandinavia to become centred over the uk. not many isobars on the charts. this isn't a strong area of low pressure. the winds will stay light. but what the low pressure will do is it will bring loads more showers oui’ way. so, for monday, we are looking at a showery picture.

quite a bit of cloud to start off with. some sunshine breaks through the cloud and then showers become widespread. the day's heaviest showers are quite likely to form across southwest england, where we'll have this zone of convergence. that's where the winds kind of bash together either side of the southwest peninsula, and that line of heavy showers and thunder storms will extend towards the south midlands and central and southern england, as well. you could see an odd heavy shower just about anywhere, to be honest, and because there's not much in the way of wind to move those showers along, well, the showers are going to be slow—moving in nature. by tuesday the jet stream starts to kick those showers and give them an extra push because we've got this trough, this bend in thejet stream moving across the uk, and that tends to encourage the air to rise upwards through the atmosphere. so, tuesday, showers again will be widespread across the country but this time more of them will turn thundery, more of them will have hail mixed in with them. there'll still be some sunshine between those showers, and the sun is stronger this time of year — so when the sun's out, it's not going to feel too bad, but when it turns cloudier,

you'll still notice a certain cool factor to the air. wednesday, showers again are in the forecast but they tend to become confined to eastern scotland and eastern england. even here the showers not as widespread and probably not quite as heavy as those on tuesday. given a bit more sunshine, it starts to get warmer — 17 in glasgow, 19—20 for the south of england and wales. for thursday, we start to see a weak build of pressure across the uk. we have to keep our eye on this feature coming in from the northwest because that could bring some showers. showers, at the moment, look like they'll be confined to parts of scotland but that feature could be a little bit more active, bringing showers more generally into the northwest of the uk. for the time being, though, looks like more of you will enjoy drier weather through thursday and there's a tendency for the weather to start to get a bit warmer as well, temperatures more widely into the high teens to low 20s. by friday, an odd shower still left on the charts. going to have to watch these showers again potentially coming up from the south, but the emphasis is, on friday,

for a lot of dry weather with some sunshine and temperatures continuing to rise a little bit, highs up to the low 20s. beyond that, we'll take a look at the couple of models that we're looking at at the moment into next weekend. they're both quite different. we've got high pressure here, the winds will be coming down from quite a cool direction but this second model, american model, shows the winds coming in off the atlantic. there is still no agreement in the forecast, really, as we head into the bulk of the jubilee holiday weekend. so the forecast is very uncertain, it is likely to change. there will be some spells of sunshine. temperatures near average. could be quite warm in the south but perhaps on the cool side in the northeast. but details of any rain and showers just not there at the moment. that's the latest.
