At 6:10 on the morning of 11 December 1987, a Guardia Civil officer at the entrance to his barracks on Avenida de Cataluna in Zaragoza watched two men park a Renault 18 directly in front of the building. When he approached to tell them parking was not permitted there, they ran. He understood instantly what was happening and sprinted back inside to wake the families sleeping above. The four-story barracks housed forty Guardia Civil families -- 180 people in total. He did not have enough time.
The Renault contained 250 kilograms of ammonal, a military-grade explosive. When it detonated, the blast tore a massive hole in the building's outer wall and brought all four floors crashing down. The explosion hit neighboring houses as well. Eleven people died, five of them children. Eighty-eight more were injured, the majority civilians -- families who had been asleep in their beds minutes before. The Basque separatist organization ETA claimed the attack, which was carried out by the Argala Commando Unit, an itinerant cell composed of French citizens who crossed back into France immediately after the bombing.
The Zaragoza barracks bombing came barely six months after ETA's deadliest attack: the Hipercor supermarket bombing in Barcelona on 19 June 1987, which killed 21 people and injured 45. Many of the Barcelona victims were women and children burned alive by the intense heat of the explosion. Spain was still reeling from that atrocity when the Zaragoza attack struck. The timing was not random. On 5 November 1987, the major Spanish political parties had signed the Pact of Madrid, a joint statement rejecting ETA's legitimacy to speak for the Basque people and ruling out negotiations until the group disarmed. The Zaragoza bombing was widely interpreted as ETA's answer to that pact -- a message delivered through the walls of a building where children slept.
The attack occurred during ETA's most violent period, under the leadership of the faction known as Artapalo, which directed the organization from the late 1980s until 1992. This era produced some of ETA's bloodiest operations, targeting not only security forces but civilian infrastructure. The Argala Commando Unit responsible for the Zaragoza bombing was dismantled through police operations in 1989 and 1992, and its members were eventually detained. Government spokesman Javier Solana was the first minister to publicly condemn the attack, in a press conference that reflected the shock felt across Spain. The barracks on Avenida de Cataluna had been an ordinary residential building with no special protective measures -- a family home that happened to house families of the Guardia Civil.
In December 2009, a monolith was unveiled at the site of the former barracks to commemorate the eleven victims of the bombing. Each year, wreaths and flowers are laid at the memorial on the anniversary. The Terrorism Victims' Association has held regular ceremonies there, ensuring that the names of the dead -- adults and children alike -- are spoken aloud in the same city where the blast silenced them. ETA declared a permanent ceasefire in 2011 and formally dissolved in 2018, but for the families of Zaragoza, the reckoning never truly ended. The five small coffins that left the ruins on that December morning in 1987 remain among the most searing images of Spain's decades-long struggle with separatist violence.
