Czech police have arrested a man suspected of planning a terrorist attack on a military site, reportedly under the direction of Russian intelligence, according to the investigative outlet Odkryto.cz.

The suspect—a 52-year-old taxi driver based in Prague—was allegedly preparing to attack a military facility using explosives.

While the target is not officially confirmed, sources suggest it was connected to the Czech ammunition initiative, a key defense program. The man reportedly operated a registered company in Prague’s Žižkov district, owned by a Ukrainian national.

Although Czech authorities have not confirmed the alleged plot, the Security Information Service (BIS) issued a public statement through the police’s account on X, noting that they are “evaluating information from both domestic and international partners.” They reassured the public that there is currently no specific threat identified.

The report comes just a day after BIS released its annual security assessment, which warned of increasing Russian and Chinese intelligence activity in Czechia. According to the agency, Russian operatives are actively attempting to recruit agents across Europe to execute acts of sabotage and disruption.

This latest incident echoes the 2014 explosions in Vrbětice, where two GRU agents from Russia’s military intelligence were linked to a deadly ammunition depot blast.

That attack killed two people and led to a significant diplomatic fallout between Prague and Moscow. The Czech government responded by expelling 18 Russian diplomats, with Russia retaliating by removing 20 Czech diplomats from its embassy in Moscow.

Security concerns have remained high since then. In March this year, a blast at an ammunition complex in Polička also raised suspicions.

Though initially attributed to a technical failure, reports later surfaced that drones had been spotted over the facility in the days before the explosion.

Police confirmed that guards did report drone activity, but the investigation has yet to confirm any link between the drones and the blast. Authorities continue to explore whether foreign interference played a role.
