All along the Ukrainian border, you hear the same thing as a tide of reluctant refugees

crosses into Poland.

Our husbands, our parents, they didn't want to go.

Even us, we also didn't want to leave, but we want to save our children, that's why we come here.

We hope that it's not for a long time and we soon will come back home.

Around 4 million Ukrainians, mostly women and children, have left the country in the past month.

Many are desperate to return.

Everyone thinks that, you know, Ukrainians are so lucky at the moment because there are so many doors open to them, but, you know, we want to stay.

Certainly the will is there to return.

Putin can change that. I mean, if he starts to gas people or chemical weapons without completely changes, then you want to make your home somewhere else.

Of those who stayed behind, a further six and a half million people have been displaced within Ukraine.

It's becoming the fastest-growing refugee crisis since World War II.

So how does it feel when war forces you to flee your own home?

You're listening to stories of our times from the times and the Sunday times. I'm Manvian Rana.

Today, dispatches from the Ukrainian border.

Pshemishal was the main place, but we drove in both directions. It's quite a sprawly border and there are a number of border crossings.

That's Roger Boyce, diplomatic editor of the Times.

He recently reported from Pshemishal, a Polish town less than 10 miles from the Ukrainian border.

It used to be a big smuggling center for that part of Europe.

And, in fact, I remember in the old days when I was a correspondent in Poland in the 90s, one of the big scandals was puppy smuggling from Ukraine.

Puppy smuggling.

Puppy smuggling.
