A bomb exploded near a nightclub in northern Spain today after a warning in the name of Basque separatist group ETA, but caused no injuries, Spanish media reports said.
A telephone warning to a Basque newspaper and the Basque highway authority gave police time to evacuate the discotheque in the small town of Santesteban in the northern region of Navarre, newspaper El Mundo's web site said.
Officials could not immediately confirm the report.
