At least three people died this week after an explosion at a large petrochemical plant outside Tarragona (Catalonia) on Tuesday evening. Six others were injured.
The first victim identified was three kilometres from the site inside his home. A metal panel, believed to be the lid of the reactor that exploded at the plant, had travelled at speed through the air, crashing through the wall of his flat.
The second victim was a boss at the factory whose remains were found on site. A further employee died in hospital on Wednesday.
The explosion caused shock waves over a wide area and fire broke out at the plant. Initially local residents were told to stay indoors because of fear of toxic gas. However emergency services later said that it was propylene, which is flammable but not poisonous.
