A bomb exploded in the Spanish pilgrimage town of Santiago de Compostela today, but caused no injuries, according to local reports.
Radio station Cadena Ser said police had cordoned off the area minutes before the blast. Other reports said the bomb had been placed in an underground car park in the centre of the town in northwestern Spain.
Police and Interior Ministry officials could not immediately confirm the report.
Basque separatist guerrilla group ETA regularly sets off bombs in Spain, often giving a warning in advance.
ETA planted a bomb in Santiago de Compostela in August last year as part of a summer bombing campaign of popular tourist centers aimed at undermining Spain's important tourism sector.
Santiago de Compostela, a scenic medieval town, attracts tens of thousands of Christian pilgrims every year to what is traditionally believed to be the burial place of the Apostle Saint James.
