A fire broke out early Saturday at the Coachella music festival in California, authorities said. No injuries were reported.

Festival goers shared video of the fire outbreak, which took place at the festival’s campsite in the early hours of Saturday, on social media.

The festival – which kicked off on Friday evening with a performance by Donald Glover’s alter ego, Childish Gambino – is one of the world’s most popular music events, with tens of thousands of people attending over its first weekend.

Some Nigerian artiste including Burna Boy and Me.Eazi have been billed to perform at the concert
