Spain’s national police have seized more than 10,000 firearms and 400 shells and grenades in raids in the northern part of the country, authorities announced Tuesday.
Police said that the arms were destined for gangs and terrorist groups, according to published reports.
The firearms included assault rifles, machine guns, pistols and revolvers.
Assisting in the operation, which was conducted in January as part of a crackdown on firearms trafficking, were counter-terror police from Madrid, Bilbao, Valencia and Gerona.
Police also stumbled upon a workshop near Bilbao set up to manipulate and reactivate decommissioned weapons, BBC reported.
Authorities seized about $90,000.
