Josu Urrutikoetxea

Ternera served in ETA and was in charge of operations in Biscay until the organisation went underground. In May 1971, he fled to Franca, Brazil at which time he joined the military front of the organisation.

In July 1972, he participated in ETA meetings in Madrid. On 15 July 1972, he attacked the Orbegozo factory in Hernani (Guipúzcoa), stealing approximately four million pesetas.

On 28 July 1972, Ternera was involved in the robbery of a van carrying foreign currency for the Bank of Biscay in the village of Pasajes (Guipúzcoa), seizing more 12,000,000 pesetas. On 6 December 1972, he participated in an attack on the Union House of Hernani.

On 21 January 1973, along with other members of ETA, he used a powder keg with more than 3,000 kilograms of dynamite and various explosive materials to plan an attack. Part of those explosives were used in December 1973 to kill Luis Carrero Blanco, who served as Prime Minister during the Franco government.

In January 1989, he was arrested in Bayonne, France with Elena Beloki, the leader of Herri Batasuna, who was later recognized as the organizer of the international apparatus of ETA. He was sent to Fresnes Prison near Paris. Later he was extradited to Spain, where he was freed when it was considered that he had been judged in France regarding his membership and financing of ETA and the other crimes of which he had been accused.

He was summoned to testify on two occasions before the Supreme Court, who investigated whether Ternera had issued the order for ETA to bomb the quarters of the Civil Guard of Zaragoza in 1987, killing eleven people, among them five children. On 26 October 1990, he was found guilty and was sentenced to ten years in prison for conspiracy, use of false documents and illegal possession of weapons.

The Office of the Public Prosecutor of the National Hearing Solicitor in July 1993 sentenced Ternera to twelve years of prison for being in charge of the international apparatus of ETA from 1984 to his arrest in 1989. After his release in France, he was handed over to the Spanish authorities on 4 May 1996.

The judge of the Audiencia Nacional, Javier Gomez de Liaño, ordered his detention. That same month, he was accused of belonging to an arms depot. In June 1996, he was declared guilty of being in charge of the bombing on the Plaza de la República Dominicana in Madrid in 1986, which killed twelve civil guards.

The former ETA member Juan Manuel Suárez Gamboa recognized that "Josu Ternera" was one of the primary leaders of ETA. In October 1996, Jose Rego maintained that "Josu Ternera" was the head of ETA in 1987, which led to Judge Gomez de Liaño reopening four cases against him.

From 2002 he was a fugitive.[1] He was detained in France on 16 May 2019.[2]

Ternera has been a member of the Basque Parliament in Vizcaya on the lists of Euskal Herritarrok and has been a member of the Commission of Human Rights.
