Sensitivities flared last month when prisoners' groups pushed for concessions from authorities, outraging victims' families. A judge at Madrid's top criminal court on Friday issued a ruling prohibiting a demonstration that was called explicitly in support of the prisoners, saying it was organized by a banned group. Basque nationalist and separatist political parties then weighed in, calling a new "rights" march on Saturday evening, which drew many supporters of the prisoners. They called for jailed ETA members to be moved to prisons closer to their families. One of them, Itziar Goienetxia, 52, said she lived in the Basque country and had to travel 745 miles there and back for a 40-minute visit to her husband in jail in the southern town of Cadiz. "It's a double sentence," affecting her as well as the prisoner, she told AFP. The conservative Basque National Party which governs the region and a left-wing pro-independence group joined forces in calling the march, in a rare joint show of strength. Between them they accounted for more than half of the votes in the last regional elections, as pro-independence Basques set their sights on a political solution. "Parties and unions that represent the political majority of this land decided they had to call this demonstration to defend the right to freedom of expression," Pernando Barrena, spokesman for left-wing party Sortu, told AFP. The spokesman for the regional government, Josu Erkoreka, earlier said the ban on the original demo was "incomprehensible to the Basque people". The victims' association AVT applied to have the new demonstration banned too, saying it gave "grave offense to each and every victim of terrorism," in a statement. "The only aim of the initiative is to pay homage to prisoners of the terrorist group ETA," the association said. A judge on Saturday ruled that the new gathering called by the parties was not illegal however, a court source said. The ETA has been weakened in recent years by the arrests of its senior leaders in Spain and France. In 2011 it declared an "end to armed activity", but refused to formally disband. Groups supporting the prisoners say there are about 520 inmates who remain affiliated to ETA, most of them dispersed in jails around Spain and France. Only a few dozen active fighters are estimated to be still at large. Agence France Presse
