A Kenyan acrobat is in hospital with serious injuries after falling through a safety net at a circus in Moscow.
An amateur video aired on Russian television showed Karo Christopher Kazungu crash through the net during the show on Wednesday night.
The Great Moscow State Circus said on its website that the 22-year-old was conscious when he was taken to hospital.
The RIA Novosti news agency quoted the director of the show as saying that Mr Kazungu was diagnosed with a fracture of one vertebra.
He was one of a dozen Russian and Kenyan performers who were taking part in a highly complex acrobatics show.
Edgard Zapashny, director-general of the circus, told Russian television that the circus had never had any incidents of this kind and that the German-made safety net had been rigorously tested at the circus before it was used.
