Dressed in the colours of Ukraine, Vladyslav Bondar, a ballet dancer, moves delicately across the stage of Rotterdam's mediaeval St Lawrence Church. He is performing with the United Ukrainian Ballet at a Salvation Army Christmas party - a setting far removed from the war in his homeland. ‘I wanted to fight for Ukraine.’ Vladyslav said after the performance, knowing it could have meant the end of his career as a professional dancer. But instead of taking up arms, he joined over 70 other Ukrainians who make up the United Ukrainian Ballet - a dance company formed directly in response to the outbreak of war. Fellow dancer Oleksii Kniazkov said, ‘Every Ukrainian has his own battlefield. And the stage is ours.’ Their dance is a dance of defiance.
