A fire believed to have been started by a flambéed pizza has killed two people and injured 12 others at a restaurant in the Spanish capital Madrid, city officials said Saturday.

“It appears the fire started when a flambéed pizza was being served, which set fire to the decorations in the restaurant,” Madrid Mayor Jose Luis Martinez Almeida told Spain’s state television TVE at the scene on Saturday, hours after the late Friday night blaze.

Spanish media reported that a specialty of the restaurant was a pizza in the flambé style - a cooking procedure where spirits are poured on the food and briefly set alight.

“Firefighters told me it was a ferocious fire in the way it started and the smoke it generated, and if the fire station wasn’t just 100 meters (around 330 feet) away, the number of fatalities could have been higher,” said Almeida, speaking to TVE.

Carlos Marin, a Madrid fire department night supervisor, said the restaurant “had just one exit, and since the fire was very close to the door, people went back to the rear of the restaurant, and they were completely trapped,” in videos tweeted by Madrid city emergency services.

The fire was quickly extinguished. Firefighters pulled 12 injured people from the restaurant, and six were taken to a hospital. That was in addition to the two fatalities, said Montse Marcos, a supervisor with the Madrid city ambulance services.

The fire was in the Plaza de Manuel Becerra, on the edge of the Spanish capital’s upscale Salamanca neighbourhood.
