SPAIN’S top criminal court is to release nine jailed militants from the Eta Basque separatist group.

The decision follows a European court ruling which overturned Spain’s extension of Eta prisoners’sentences.

The group is considered by some to be a terrorist organisation.

A violent 40 year campaign by Eta resulted in more than 800 people being killed.

The group called a ceasefire in 2011.

The court’s decision was narrowly in favour of releasing nine prisoners and keeping two others behind bars. Nine judges were in favour and eight were against.
