WOMADelaide stage destroyed by fire

The main stage at WOMADelaide has been destroyed by fire, hours after English singer-songwriter Billy Bragg performed the last act at the festival.

Emergency services were called to the stage in Adelaide's Botanic Park just before 6.30am (CDT) on Tuesday.

Police say the fire was put out but extensive structural and equipment damage was caused.

Thousands of people attended the four-day world music, arts and dance festival which ended on Monday night.

Investigators will determine what caused the fire.
