A senior leader of the Basque militant separatist group ETA has been arrested in the French Alps after being on the run for 17 years, according to Spanish authorities.
José Antonio Urruticoetxea Bengoetxea, widely known by the alias Josu Ternera, has been ETA's most-wanted member since 2002.
ETA's initials stand for "Basque Homeland and Freedom" in the Basque language. The group is estimated to have killed more than 850 people during its violent, decades-long campaign to create an independent state in northern Spain and southern France.
