PRAGUE – In a landmark ruling on Tuesday, a regional court in Brno, the Czech Republic’s second-largest urban center, has handed a 20-year-old man a combined seven-year prison sentence for his central role in a foiled terror attack and attempted murder targeting a local Jewish synagogue.
Court documents confirm the defendant, who was just 17 when the plot was carried out in January 2024, planned the arson attack alongside a second underage accomplice. The pair constructed a homemade incendiary device with the explicit goal of setting fire to Brno’s active synagogue and murdering an individual present at the site. The intended victim escaped the attack unharmed, and the incendiary device failed to cause significant structural damage to the place of worship, thwarting the attackers’ deadly plans.
In addition to the seven-year term for the attempted attack and murder, the court added a consecutive two-year prison sentence for separate charges of promoting terrorism. That offense was committed after the defendant turned 18, making him eligible for prosecution as an adult on that count.
Legal authorities confirmed that the defendant’s accomplice, who remains under the minimum age required for public criminal trial in the Czech Republic, has already had their closed-door hearing completed. No details of the accomplice’s case can be released to the public due to Czech juvenile privacy regulations.
The plot is part of a broader interconnected radicalization network uncovered by Czech law enforcement last year. The defendant and his accomplice are two of five teenagers arrested in a cross-border operation targeting a network that officials say was radicalized online by the transnational militant group Islamic State.
Investigations into the group revealed that all five members spread virulent hate speech across multiple social media platforms, targeting Jewish communities, the LGBTQ+ population, and other ethnic and social minorities across Central Europe. Coordinated raids carried out by police in both the Czech Republic and neighboring Austria uncovered a cache of weapons, including edged weapons such as knives, machetes, and axes, alongside several gas pistols.
Officials added that the group participated in private online forums dedicated to recruiting new fighters to join Islamic State militant operations in Syria. All members shared an open obsession with extreme violence and echoed the group’s violent ideology targeting marginalized groups.
The investigation was a cross-border collaborative effort, with Czech law enforcement coordinating closely with law enforcement counterparts in Austria, the United Kingdom, and Slovakia, as well as Europol, the European Union’s dedicated cross-border law enforcement agency, to dismantle the network and prevent further planned attacks.
