An environmental activist wearing a T-shirt with the message ‘We have 1028 days left’ interrupted the French Open men’s semi-final between Casper Ruud and 2014 US Open champion Marin Cilic by attaching herself to the net with metal wires and glue and kneeling on the court.

Play was delayed for 13 minutes during a game with Ruud serving in the third set while leading 3-6, 6-4, 4-1, 15-all at Court Philippe Chatrier.
