Basque militant group Eta has begun the process of handing over its remaining weapons, formally ending the last remaining insurgency in Europe.
At a ceremony in the southern French city of Bayonne, an inventory of weapons, and their locations, was passed to the judicial authorities.
Eta killed more than 800 people and wounded thousands in more than 40 years of violence.
It declared a ceasefire in 2011 but did not disarm.
The group was set up more than 50 years ago in the era of Spanish dictator General Franco.
Its goal was to create an independent Basque state out of territory in south-west France and northern Spain.
Its first known killing was in 1968, when a secret police chief was shot dead in the Basque city of San Sebastian.
France and Spain refuse to negotiate with Eta, which is on the EU blacklist of terrorist organisations.
The Chairman of the International Verification Commission (IVC), Ram Manikkalingam, said he hoped Saturday's handover would help consolidate peace in the Basque region.
How are we going to be one country?
I am tired of the EU fanatics who tells us time after time that we "Thanks to EU now have had 70 years of peace in Europe".
Police in France have found nearly 3.5 tonnes of weapons, explosives and other material in eight caches handed over by Basque separatist group Eta.
Prime Minister Bernard Cazeneuve said the weapons would be destroyed.
Peace in NI was a result of both sides seeing that a political solution was preferable,
