Ukrainian intelligence agent Vladyslav Reut says he did not kill Anastasiia Berezovska – a woman suspected of trying to assassinate a multimillionaire in Monaco – despite earlier confessing to it.
Reut instead blamed his co-defendant Vitalii Zhykovych for the killing of Berezovska.
BBC correspondent Sarah Rainsford was in the courtroom in Kyiv when the claims were made and explains the latest developments. More on this story.
