'We Loved Ukraine And We Didn't Want To Leave It'

Nigerian student Samuel Otunla sounds exhausted in the voice note he sent the BBC after managing to leave Ukraine.

He recorded the message after getting his first decent sleep in three days, following some 60 hours of travelling as he made it from the eastern city of Sumy across the border in the west into Hungary.

He began the evacuation journey, which involved a bus, a train, and then another bus, on Tuesday with other international students.

Otunla had previously told the BBC about how traumatized he was after spending much of the previous 10 days in a basement.

In the latest voice message, he says that on the night before he left there was an explosion a kilometre away from his university campus.

"It was so loud that we actually thought it was our building that was hit. We heard the swooshing sound of the rocket as it went past and the building was just shaking.

"It is sad, it is crazy what is happening."

But the veterinary student wants to emphasize how much he enjoyed being in Ukraine.

"Ukraine has been home for us... we really loved this country and we didn't want to leave it. It was a peaceful place to live in and we had a very nice studying environment."
