Germany has stated that the attack at Leipzig airport is part of a series of "Russian hybrid operations" in Europe. As temperatures in Europe reached record highs, Russia intensified military attacks in Ukraine and appeared to escalate its sabotage efforts across Europe, targeting military and defense sector sites. A month after drones filled with explosives were discovered at Leipzig airport, which is used for transporting military goods to Ukraine, Germany's interior minister declared that "Russia is responsible" for the incident. In response, Russian President Vladimir Putin demanded evidence and dismissed the accusations as "absurd."
Following the drone incident, August saw a series of suspicious fires at defense facilities across several countries, including Italy and Estonia, with some nations attributing the incidents to Russian involvement while others continue to investigate.
On August 4, the first drone was discovered at Leipzig airport. On August 10, a major fire broke out at a defense firm warehouse in Bulgaria, with the company recalling previous incidents linked to Russia. On August 13, a fire at an ammunition facility in Italy triggered a large explosion, and the local prosecutor opened a case for negligent disaster against unknown persons. On August 15, a fire at a robotics factory in Estonia led to two arrests, with the Prime Minister stating that Russian sabotage was being taken seriously.
On August 25, Slovakian police thwarted an arson attack on a Ukrainian-owned drone manufacturer, arresting three suspects allegedly following orders from Russia. Poland reported additional fires, including one at a helicopter component manufacturer, with Prime Minister Donald Tusk stating that arson could not be ruled out.
The pattern of attacks has continued into September, with two Bulgarians arrested in Munich for suspected arson at a defense firm. Authorities are also investigating a separate case of sabotage at power substations in western Germany.
Experts suggest that the recent surge in attacks on military sites is unusual and may be linked to developments in Russia's invasion of Ukraine. Daniela Richterova from King's College noted that the intensity of these attacks indicates a shift in Russia's strategy, possibly aimed at coercing countries to reduce support for Ukraine.
Keir Giles from Chatham House argued that Russia is testing NATO's response and assessing vulnerabilities. The International Institute for Strategic Studies (IISS) reported over 165 suspected sabotage cases in Germany this year, though the responsible parties were not identified.
The majority of sabotage attacks in Europe are believed to be carried out by Russian proxies, often recruited online. The IISS compared these operatives to disposable kamikaze drones, emphasizing their potential for reckless actions. If the recent drone launch at Leipzig was conducted by professionals, it suggests a desire for precision and success.
Richterova's research indicates that Russia's sabotage tactics resemble Cold War strategies, with small, deniable attacks intended to escalate during wartime. The increasing frequency of these attacks raises concerns about potential accidental escalation and the need for NATO to respond to a sustained Russian assault.
