French officials say they found two portable anti-aircraft missiles among weapons seized in Sunday's raids against suspected members of Spain's Basque separatist group, ETA.
French authorities said Tuesday the surface-to-air missiles were found under houses in Urrugne and Briscous in southwestern France, near the Spanish border.
Authorities identified the weapons as Soviet or Russian-made SAM-7 missiles.
The raids led to the arrests of ETA political leader Mikel Albizu Iriarte and other suspected separatists fighting for an independent Basque state in the region.
More than 800 people have been killed in the violent ETA campaign that has continued for more than four decades.
