Preparations Acting on orders received from the ETA leader Santiago Arrospide Sarasola, "Santi Potros", three members of ETA's "Barcelona Commando" Josefa Ernaga, Domingo Troitiño and Rafael Caride Simón, decided to place an incendiary bomb inside a Hipercor store. The three visited various commercial centres and selected one where a car could be parked. They then met in a flat in Carrer Castelldefels, Barcelona,
Catalonia, Spain, and assembled a bomb containing of
ammonal and 100 litres of gasoline together with a timer device and an indeterminate quantity of glue and flakes of soap to create a bomb weighing up to . This was then placed in a stolen
Ford Sierra.
Bombing The attack occurred on a Friday afternoon. The car bomb, hidden in the boot of the vehicle, had been placed on the first floor of the three-storey subterranean car park below the commercial centre. At approximately 16:12, a timer activated the bomb which exploded, destroying 20 vehicles parked nearby and causing a hole of around 5 metres in diameter in the ground floor of the shopping centre through which a huge ball of flame penetrated. Several of those unaffected by the flames were asphyxiated by the toxic gases produced, causing several fatalities. The damage at the scene was so extensive that several of the corpses could not be located until two hours later and some had been burned so severely that identification was impossible. Initially 15 people were killed, of whom ten were women (one of whom was pregnant), three men and two children. However, the death toll then rose to 21, as six victims succumbed to their injuries. ==Telephone warnings==
