Immediate suspicion for the latest car bombing in Spain has fallen on the armed Basque separatists ETA. The group’s last deadly strike came in June. That saw the killing of a police officer after his car was booby-trapped in the northern city of Bilbao.For many Spanish people, there is widespread revulsion at the violent methods employed. Spain’s Socialist government broke off peace talks with ETA in 2006 after a car bombing in Madrid and has refused to negotiate with the group since. The recent arrests of several suspected members, including its alleged military chief, have arguably weakened the separatists. Even so, despite waning support, if ETA is behind this latest strike it also shows it is still able to mount attacks. More than 800 people have been killed in the armed group’s four decade campaign for an independent Basque country.
