(FILES) This file photo taken on August 23, 2002 shows former ETA activist and pro-independence Basque nationalist party Batasuna regional parliament's deputy Jose Antonio Urrutikoetxea, alias "Josu Ternera", during a demonstration against the expected illegalisation of Batasuna in the Spanish northern Basque city of Bilbao. - The fugitive former leader of the Basque separatist group ETA was arrested in France on May 16, 2019, Spain's interior ministry said, after years on the run. Jose Antonio Urrutikoetxea Bengoetxea, better known as Josu Ternera and who was once ETA's political chief, was detained "in the early hours of the morning in Sallanches in the French Alps," the ministry said. ETA killed more than 800 people in more than four decades of violence for an independent Basque state. (Photo by Rafa RIVAS / AFP)
