An explosion at a fireworks factory in Spain killed at least five people and wounded six on Monday, in the town of Pinesque located in Zaragoza Province, according to officials.
The cause of the blast that occurred near the airport in the outskirts of the city is unknown, but it was heard miles away and neighbours said they felt the ground shake, EFE has reported.
As Spanish television displayed images of large amounts of smoke rising from the factory warehouses, a spokesman for the fire service said "Firefighters are at the scene and there are still small explosions going off."
Emergency services warned the locals to keep away from the area.
The Pirotecnia Zaragozana factory, which exports products to other European countries and Canada, has around 40 workers.
The company which produces fireworks and matches, had a similar case more than 30 years ago, when several blasts destroyed almost a dozen warehouses, according to El Pais.
August is a busy time for such factories, since there are many religious festivals this time of the year.
