A bomb that exploded outside a courthouse in northern Spain this morning came after a warning call was made in the name of Basque separatist group ETA, a police source said.
"The explosion happened at 6 a.m. on the dot (5 a.m. Irish time), injuring one person who was passing by in a van," the source said.
The bomb was placed at the doors of a courthouse in Estella, Navarre, a province claimed by Basque separatists as a part of a greater Basque homeland.
Police said a warning call in the name of ETA had been made to a motorway assistance association shortly before the explosion.
ETA has killed more than 800 people in a three-decade campaign for an independent Basque state in northern Spain and southwestern France.
On Tuesday, bombs weent off at two hotels in popular Spanish seaside resorts Benidorm and Alicante, after a warning call in the name of ETA. Thirteen people were injured, two seriously.
