Nearly 3.5 tonnes of arms and explosives have been handed over to French police by the Basque separatist group ETA.
The French Prime Minister Bernard Cazeneuve says he welcomes the surrender, which follows more than 40 years of violence aimed at splitting from Spain.
The weapons were recovered from various locations identified by ETA.
More than 800 people died as a result of the violence from 1960 onwards.
