An armed cell of one of the world’s most violent neo-Nazi terror groups was actively preparing attacks in Spain, it has emerged.
It comes after the Spanish arm of The Base, whose global leader is US national Rinaldo Nazzaro, was dismantled in Castellon last week.
The Policia Nacional recovered a tranche of guns, including silencers, multiple machetes and blades and survival manuals.
More worryingly, sources told Cadena Ser, were operational documents pointing towards plots that involved killings and attacks on ‘critical infrastructure’.
The Base pushed for accelerationism – the belief that society must be violently destabilised to provoke a ‘race war’.
Nazzaro, who once worked in US military-intelligence contracting roles before resurfacing in St. Petersburg, is believed to run the network from Russia.
His group openly praises ‘lone-wolf’ jihadist tactics used by al-Qaeda, seeking to replicate them for white supremacist violence.
According to intelligence briefings seen by SER, the Spanish contingent had already crossed the threshold from rhetoric to preparation.
Officers found tutorials for improvised weapons, assault tactics, maps of presumed targets, and planning documents mirroring those of other accelerationist groups such as Atomwaffen Division and Feuerkrieg Division.
Among the manuals discovered was a guerrilla-style guide advising recruits to travel light, carry food for 48–72 hours and use semi-automatic rifles.
The instructions are identical to those circulated between accelerationist cells across Europe.
The Spanish cell allegedly intended to strike ‘traitor whites’ ethnic minorities and key infrastructure such as telecommunications or energy networks.
The ultimate objective, according to analysts, was to provoke retaliatory violence and ignite the ‘racial collapse’ fantasised about in extremist forums.

Although the group lacked sophisticated arsenals, the combination of ideological zeal, tactical manuals and early planning phases meant its threat level was categorised as ‘high’.
Members performed identity ‘oaths’, discussed combat roles and circulated violent propaganda through closed channels on Telegram and VK, the Russian social network.
During the raids, officers recovered flags emblazoned with skull insignia, SS lightning bolts, the ‘Black Sun’, and the initials ‘HH’ – all staples of violent neo-Nazi subcultures.
Spanish intelligence services have long monitored individuals linked to these networks, including a previous case in 2020 in Lleida, where extremists attempted to form an isolated all-white settlement and plotted mass casualty attacks.
The dismantling of the Castellón cell marks the first confirmed presence of an organised branch of The Base inside Spain.
‘They were transitioning from theory to action,’ a senior counter-terrorism source emphasised. ‘Had they not been interrupted, the next phase would have involved concrete attack planning.’
The investigation continues.
