A bomb exploded at the headquarters of the Banco de Vizcaya at No. 1, Gran Via, beside the Plaza de España in Bilbao. Two members of ETA’s José Martí unit entered the bank offices while another waited outside. They left the bomb in a briefcase next to the Foreign Exchange Department. On spotting the briefcase, the employees joked that it might be a bomb, without taking the matter seriously.
ETA gave several bomb warnings, but the bomb exploded just three minutes later. Ramón Iturriondo García, cashier at the bank, and Aníbal Alfonso Izquierdo Emperador, an orderly, were killed instantly in an attack later referred to by ETA as a ‘technical error’ and a ‘regrettable incident’, in a communiqué published in Egin newspaper. Another ten people suffered injuries, some critical, including Benicio Alonso Gómez, who died two days later.
