An explosive device was placed outside the offices of the Civil Guard in Palmanova, on the holiday island of Mallorca, a few kilometres from where members of Spain’s royal family were holidaying.As the hunt for the killers began, police later deactivated another bomb placed beneath a second car near the site of the first explosion. In what has been termed “Operation Cage” by the government, the island’s ports and airports were briefly closed to prevent the bombers’ escape. Tourists are having to adapt to inconveniences resulting from the tightened security which is set to continue. Although ETA has not claimed responsibility for yesterday’s bomb and Wednesday’s blast at a barracks in northern Spain, politicians see them as grim reminders of ETA’s deadly capability. They had hoped to portray the group as weakened after a number of high profile arrests.
