 The Madrid–Barajas airport had also been the location of ETA attacks on July 29, 1979, when three civilians were killed, and on August 27, 2002, when a car bomb exploded on the second floor of the Terminal 2 parking, causing only material damage, after a warning call from the armed organisation.In two meetings held at the Baztan valley in Navarre in the summer of 2006, Txeroki, then head of commandos, ordered fellow ETA members Mattin Sarasola, Igor Portu and Mikel San Sebastián to carry out the bombing.The three members had been born in the Navarrese town of Lesaka and were part of the "commando Elurra" (), previously known as "Goiztiarrak", formed in 2002.
