Originally based in San Sebastian in Basque country, Gurruchaga, who is herself Basque, was forced to move both her home and her office several times, because of repeated threats and harassment. Then, in December 1997, when Gurruchaga wrote an article identifying the location of an ETA extremist, the terrorist group retaliated by bombing her home while she was inside with her two young children. Following the attack, Gurruchaga relocated to Madrid.
Though she is still on ETA's hit list, she continues reporting on them for El Mundo and is also a regular commentator for Spanish national television and radio.
