Volkswacht Bodensee - Four dead, 14 missing after fire guts Spanish apartment block

Experts said the building, which contained 138 flats, was covered with highly flammable cladding, which could account for the rapid spread of the blaze after it broke out on the fourth floor at around 5:30 pm (1630 GMT) on Thursday.

Dramatic images showed clouds of black smoke as the flames consumed the high-rise in the western Campanar neighbourhood of the port city.

"Four people have died," Jorge Suarez Torres, deputy director of emergency services for the Valencia region, told reporters overnight.

"As of now, we have 14 people who remain untraced," regional administrator Pilar Bernabe added on Friday, stressing that the number could change.

Valencia mayor Maria Jose Catala had said between nine and 15 people were unaccounted for, based on information provided by police and neighbours, while a city hall source had said on Thursday that 19 people were unlocated.

Fifteen people were treated for injuries of varying degrees, including a seven-year-old child and seven firemen.

Six of the 15 were still in hospital on Friday but their lives were not in danger, regional governor Carlos Mazon said.

Officials said 22 teams of firefighters had been called in to battle the blaze.

Suarez Torres said they had not yet managed to get into the building.

"We're trying to cool the facade. That's our goal over the next few hours," he said.

"We can't say when we'll be able to get inside."

- Combustible cladding -

Spanish media said rescue workers had used drones to locate the bodies of those who perished.

Esther Puchades, deputy head of Valencia's Industrial Engineers Association (COGITI), told local media the fire had spread so rapidly because the building was covered with highly combustible polyurethane cladding.

Luis Ibanez, who lives nearby, told TVE he had looked out of a window and seen the flames engulfing the building "within a matter of minutes".

"(It was) as if it was made of cork," he said.

"I couldn't believe what I was seeing. The whole side of the building directly opposite was on fire, from the first floor to the sixth and seventh floor," he said.

"There was a really strong wind and the fire was spreading to the left at a huge speed."

Neighbours who gathered outside expressed shock at the scene and the thought of people being trapped inside.

"It makes your hair stand on end, the thought that people are inside and really suffering. It's a disaster because there could be people in there dying," Julia Pascual told AFPTV.

Footage on social media that was reposted by Spanish media outlets showed a father and daughter being rescued from a balcony where they were trapped.

- 'It could have been me' -

"It's absolutely horrible. It gives you goosebumps to think about those people inside," said another local, Luis Alberto Clarin, who had just come home from work.

"It could have been me. It could have been my building."

Spanish Prime Minister Pedro Sanchez said he was "shocked by the terrible fire" and was in contact with the mayor and the regional governor "to offer whatever help is needed".

He extended his condolences to everyone affected by the blaze.

In October, a fire gutted a nightclub in the neighbouring region of Murcia, claiming 13 lives in what was Spain's deadliest nightclub fire in three decades.

In that incident, a fire at the 24-storey high-rise in west London killed 72 people.

The blaze spread rapidly due to the highly combustible cladding on the block's outside walls. A public inquiry into the disaster has yet to publish its final report.
