Spanish authorities say a powerful car bomb has heavily damaged a Civil Guard barracks in the northern city of Burgos, lightly injuring about 60 people.

Spain's Interior Minister Alfredo Perez Rubacalba blamed the Basque terrorist group ETA for the early-morning attack.  The multistory barracks housed members of Spain's paramilitary police force and their families - 120 people, including 41 children.

The minister said the perpetrators undoubtedly were trying to kill those inside.

ETA has killed more than 825 people since the late 1960s in its push for an independent Basque state in northern Spain and southwestern France.
