General images from Melbourne Airport on Thursday morning. Australia said Thursday it had cancelled the entry visa of Novak Djokovic, opening the way to his detention and deportation in a dramatic reversal for the tennis world number one. The Serb had landed in Melbourne the previous evening, after celebrating on social media that he had a medical exemption to play in the tournament without proof he was fully vaccinated against Covid-19. The player was held at the airport overnight, but was moved, along with his team, early on Thursday. ATTN CLIENTS: VIDEO DOES NOT CONTAIN IMAGES OF DJOKOVIC IMAGES
