A sold-out open-air concert by Puerto Rican reggaeton star Bad Bunny was cut short in Milan on Saturday night after a severe hailstorm swept through the venue, injuring several attendees and forcing the evacuation of around 80,000 fans.

The show was taking place at the Snai La Maura Hippodrome, a large racetrack venue on the outskirts of Milan, as part of Bad Bunny's ongoing world tour. The storm struck after the artist had performed just five songs, bringing large hailstones, strong winds, and heavy rain down on the crowd. Videos shared widely on social media showed drenched concertgoers scrambling for shelter beneath umbrellas, trees, and covered structures as hailstones pelted the open grounds.

Initially, an announcement was made asking the audience to remain in place while the concert was briefly paused. However, as conditions worsened beyond initial expectations, organisers decided to cancel the performance entirely. Fire service officials confirmed that multiple people sustained injuries after being struck by hailstones on the head. Ticketing and events company Live Nation, which organised the event, confirmed the cancellation and announced that all ticketholders would receive full refunds. It remains unclear whether a rescheduled date will be offered.

The incident highlights the growing challenges of staging large open-air events as extreme weather episodes become more frequent across Europe during summer months. Milan and the broader Po Valley region of northern Italy are particularly prone to sudden, intense thunderstorms in summer, when warm humid air from the Mediterranean can collide rapidly with cooler Alpine air masses. The scale of Saturday's disruption — tens of thousands of people caught in a sudden storm at a single venue — underscores the safety risks such conditions can pose even at professionally managed events.
