Three bombs in Basque Country, ETA claim-radio

MADRID, May 1 (Reuters) - Three small bombs exploded early on Thursday in the Spanish Basque Country city of San Sebastian and a nearby town after a warning call claiming to be from Basque separatist rebels ETA, Spanish radio said.

The caller warned of the two bombs in San Sebastian near a public building but not of another device which exploded shortly afterwards in the town of Arrigorriaga. None caused any injuries, Cadena Ser radio reported.

No police spokesman was immediately available for comment.

ETA has killed more than 800 people in four decades of armed struggle for independence for the Basque Country from Spain. The guerrilla group's last fatal attack was believed to be on March 7 when, two days before a general election, a former councillor from Spain's governing Socialist Party was shot dead in the Basque town of Mondragon.
