The armed Basque separatist group ETA claimed responsibility for the killing of a civil guard in a bomb attack this month, in a statement on Friday.

ETA said it carried out the bombing which killed 41-year-old Juan Pinuel Villalon at a civil guard headquarters in the northern Spanish Basque region on March 14, as well as three other attacks, in a statement sent to the pro-independence Basque newspaper Gara.
