Eurovision win brings 'incredible happiness' to Ukraine
"When they said that we had won, I shouted at the whole apartment," said Ivanna Khvalyboga, who was forced to flee Ukraine following the invasion.
Speaking from Poland, she told the BBC the win meant "incredible happiness for Ukraine and Ukrainian people".
Kalush Orchestra won the competition, beating the UK and Spain to clinch the top spot.
The group had been predicted to take the title as support rose following Russia's invasion.
