ETA performed their first car bomb assassination in Madrid in September 1985, resulting in one death (American citizen Eugene Kent Brown, employee of Johnson &amp; Johnson) and sixteen injuries; the Plaza República Dominicana bombing in July 1986 killed 12 members of the Guardia Civil and injured 50; on 19 June 1987, the Hipercor bombing was an attack in a shopping centre in Barcelona, killing 21 and injuring 45; in the last case, entire families were killed. The horror caused then was so striking that ETA felt compelled to issue a communiqué stating that they had given warning of the Hipercor bomb, but that the police had declined to evacuate the area. The police said that the warning came only a few minutes before the bomb exploded.
