More than 22,000 people were evacuated from the Tomorrowland music festival in Barcelona on Saturday night after a huge fire broke out on one of the stages.
Emergency services at the scene said the fire broke out during a sequence on stage involving fireworks.
The fire was reported to have broken out on the main stage last night at the electronic music festival, after the left side of the stage became engulfed in flames.
Emergency services say no one was injured.
In a statement, organisers said: "Tonight, July 29th 2017, the UNITE Barcelona stage caught fire due to a technical malfunction"
"Thanks to the professional intervention of the authorities all 22,000 visitors were evacuated safely and without reports of injuries," it said.
It added: "Authorities will follow up and continue the investigation with the local Spanish organizer of UNITE."
The festival was taking place just north of Barcelona in Santa Coloma de Gramenet. It was the first time it had been held in Spain - one of eight countries hosting Tomorrowland events this year - with live streaming from the main event in Belgium.
Tomorrowland's stage is always very ornate and in the past has been decorated with giant trees, magical story books and even a man made erupting volcano.
