No one was hurt Monday when a bomb exploded at the childhood home of Spanish veteran politician Manuel Fraga, authorities said.

The blast did little damage to the building, scheduled to be inaugurated this week as the headquarters of the Manuel Fraga Foundation, according to the mayor of Villalba, the town in the northwestern region of Galicia where the politico was born.

Gerardo Criado said the explosion broke the door of the foundation and the windows of two adjacent houses and also knocked down the sign of a nearby drugstore, but there was no additional "material damage, and no personal (damage)."

First indications are that a group desiring independence for Galicia could be behind the bombing.

The Nationalist Galician Bloc condemned the attack in a communique in which it said that violence "has no place" in Galician society, that it has a "clear pacifist conscience" and that it "finds any type of attack (against people or property) enormously repugnant."

The headquarters of the Manuel Fraga Foundation holds a large part of the political and personal legacy of the founder of Spain's conservative Popular Party, including his library.

Fraga, upon turning 89, announced at the beginning of September that he was leaving political life at the wishes of his family, putting an end to 60 years of public service.

A Cabinet minister during the final years of the Franco dictatorship, Fraga was one of the fathers of Spain's 1978 Constitution.
