Hello, I'm Karnishap on the BBC World Service and this is BBC OS Conversations Surviving in Ukraine.

We continue to hear the stories of Ukrainians as Russia's military invasion intensifies.

Across the country, our guests share their experiences of fear, hope and survival,

including a couple in Harkiv, a city which has been besieged by missiles.

Our first son, our elder son, is with us and we have another one in Poland, not of course I'm very,

very worried about him being an orphan. This is my biggest concern.

For more than a week, many of those who remain in Ukraine have been living underground in bunkers,

a shelling and gunfire takes place on the streets above. The escalation of the attacks across

multiple cities also forced many Ukrainians to flee their homes. The United Nations estimated

more than a million people had left the country and plenty of others were on the move inside

Ukraine searching for a place to shelter. Each day we've been hearing from those affected by the war.

Earlier, my colleague James Reynolds spoke to two women who decided to leave the capital here

in the city of Kyrgyzstan, and travelled across Ukraine in the hope of keeping their families safe.

They are Leubo Valitsko and Sasha Ambrose, who told us how her journey began.

We woke up by the blasts, so we had all our stuff ready before.

My husband, me, we took our cat, jumped into the car with all the documents and we drove

to the western Ukraine to my husband's relatives. We left at 6 and we came here at 3am.

Did you have to say goodbye to anyone?

Yes, I left my parents there and my two grandmums and one grandfather. He's in the wheelchair

and he lives in a building with no elevator, so I had very emotional good bye to him because

I asked him to come with us because we could have helped him to come down the stairs,

but he said no, he won't go and we have a very tough decision to make to leave them there.
