Basque separatist group ETA may disarm and disband, if able to successfully negotiate the release of prisoners with the Spanish government.
The group has released a statement saying they are also willing to demilitarise the Basque region of Euskadi.
Among others, ETA may want to talk about the release of Izaskun Lesak, a suspected ETA leader arrested in France in October.
With members of the group also based in France, French Interior Minister Manuel Valls has said his country must work with Spain in the fight against ETA.
Two people were killed by a bomb planted by the group at Madrid’s Barajas Airport in 2006.
ETA is believed to be responsible for more than 800 deaths and is considered a terrorist organisation by the EU and US.
