Just hours before tennis great Roger Federer was set to play his final match ever at the 2022 Laver Cup, a match between Stefanos Tsitsipas and Diego Schwartzman was halted on Friday after a British protester stormed the court and lit his arm on fire to protest the use of private jets.

A man wearing a T-shirt that read "End UK Private Jets" ran onto Center Court at the O2 Arena in London where he proceeded to light his arm on fire.
