A powerful car bomb exploded in Madrid Wednesday after a warning call from the armed Basque separatist group ETA, police said, in the latest of a string of attacks since Spain's prime minister offered talks with the group if it renounces violence. Three people were slightly injured, the city's emergency medical department told Spanish news agencies. The explosion occurred at around 9:30 am (0730 GMT) in the working-class San Blas district in the north of the Spanish capital. Prime Minister Jose Luis Rodriguez Zapatero, speaking in a previously scheduled Senate session shortly after the explosion, insisted that "the only fate that the terrorist group ETA has is to lay down weapons and dissolve." The blast was the sixth blamed on ETA since Zapatero announced earlier this month he was willing to hold talks with the separatist group if it renounced its decades-old campaign of violence, according to a report of The Associated Press.
