Spanish pop star Joana Sainz García was fatally injured when a pyrotechnic device exploded on stage during a performance early Sunday.

Some 1,000 fans were watching the concert at a music festival near Madrid when a device blew up during the light show, eliciting screams from the audience. A projectile struck the 30-year-old performer, and she fell to the stage unconscious, officials said.

A physician and nurse in the audience attempted to help the singer before paramedics arrived, according to El Diario Montanes. She was declared dead at a hospital.

Sainz García, a singer and dancer, was performing with the 15-member Super Hollywood Orchestra group in a town near Madrid at the time. The performers were closing out a four-day festival in Las Berlanas.

El Norte de Castilla obtained video footage of the explosion. It can be seen below.
