Investigators found what they believe is explosives meters from a crashed drone near the Bundeswehr's Wunstorf air base in Lower Saxony, Germany, and the device matches the construction of drones used in the GRU-attributed Leipzig airport attack, Süddeutsche Zeitung, NDR, and WDR reported on 22 September. Germany's federal prosecutor and the Federal Criminal Police Office (BKA) have taken over the investigation, and the same reporting traced one of the Leipzig suspects to a sanctioned GRU colonel who directs sabotage against countries arming Ukraine.

Russia's sabotage campaign against countries supporting Ukraine has escalated from arson packages and recruited proxies to explosives-laden drones targeting military infrastructure inside NATO. Germany's military counterintelligence has attributed repeated sabotage on German soil to Russia, while Finnish President Stubb called the broader alarm about Russian threats an "overreaction"—a position the accumulating evidence from Germany and Poland does not support.

Explosives found days after the drone crash

A farmer discovered the drone, broken into several pieces, on the evening of 14 September, about one kilometer from the Wunstorf air base, Militarnyi reported. Days later, police found a suspicious substance just meters from the crash site. Security sources told SZ, NDR, and WDR they believe it is an explosive, though forensic analysis has not yet been completed.

The drone's design is similar to the devices used in the Leipzig airport attack on 4 August, when attackers tried to destroy Ukrainian cargo planes with explosives-laden drones. At least one component was manufactured using a 3D printer, the reporting found. Investigators believe the drone may have been near the military airfield for a long time—possibly up to two years.

Wunstorf air base houses the Bundeswehr's entire A400M transport fleet. The facility is Germany's central hub for moving troops and materiel worldwide. An explosives-laden drone near this base would represent a direct threat to the Bundeswehr's central global logistics hub.

The Wunstorf find was discussed at the weekly intelligence briefing in the Chancellery on 22 September, the outlets reported.

Leipzig suspect linked to sanctioned GRU colonel

The federal prosecutor's investigation connects the Wunstorf case to the Leipzig attack. In that case, Germany's government has officially blamed Russia. Two suspects were identified: Oleg L., a Latvian with a Russian passport, and Andrei K., a dual Belarusian-Russian citizen whose DNA was found at the Leipzig scene.

SZ, NDR, and WDR reported that Oleg L. maintained years-long contacts with GRU Colonel Denis Smolyaninov. The EU sanctioned Smolyaninov for directing sabotage operations against countries supporting Ukraine. Andrei K. had previously been noticed for minor offenses in the Baltic states and Finland and entered Germany on an Italian tourist visa. Moscow denied involvement in the Leipzig attack.

A drone violated the no-fly zone around NATO's missile shield base in Poland

The Wunstorf case came to light in the same week that a drone violated the no-fly zone around the US-operated Aegis Ashore missile defense base in Redzikowo, northern Poland, on 15 September.

Polish troops guarding the facility called civilian emergency services instead of neutralizing the drone, TVP World reported. Poland's defense ministry said the drone was a civilian device that "posed no threat" and remained under military surveillance, but Defense Minister Władysław Kosiniak-Kamysz ordered a full report into the incident.

German security services can now name two suspects in the drone attack on Leipzig/Halle airport with high probability, one of them attributed to Russian military intelligence, Welt am Sonntag reported, citing secret investigation files it obtained. The paper says that evidence is what allowed Berlin to blame Russia publicly a week and a half ago. Russia has denied any involvement.

The two men

The main suspects are a Belarusian citizen, Andrei Ka., and a Russian, Oleg Le., according to security sources cited by the paper. German investigators believe Le. was responsible for the preparation and logistics of the attack, and attribute him to the GRU, Russia's military intelligence agency.

Le. entered Germany through Türkiye, landing at Berlin Brandenburg airport, and later left from the same airport for Serbia. He is now back in Russia. Investigators knew at the point of entry that he was tied to the GRU's circle, and he was not surveilled afterward.

What was on the drone

The attack used three drones at Leipzig/Halle airport on the evening of 4 August, and two were destroyed at launch for reasons still unclear. The third landed beside a Ukrainian transport aircraft and sat there for hours. About 1.8 kg of Semtex, built into a vegetable can, failed to fire because a detonator tore loose. The Antonov it reached held 25,000 liters of kerosene, and investigators estimate a detonation would have destroyed parts of the airport.

How the trail was found

Forensic technicians recovered glove remains with DNA traces from the antenna used to fly the drone, and those traces were already on file in Finland and Lithuania, where Ka. has a record for ordinary criminal offenses, including theft in Finland. Polish prosecutors separately link him to a hardware-store fire in Łódź in the summer of 2024 that they treat as sabotage directed from Russia, which fits the pattern European authorities have documented since 2022: Russian services hiring residents, often migrants, to burn warehouses and malls. The Leipzig explosives are thought to have crossed from Bulgaria through Serbia in truck cavities and gone into buried caches, and police found several suspected hiding places after examining the suspects' rental-car data.

Germany suspects Russian intelligence behind arson attack as hybrid warfare threat grows across Europe

What Berlin has done about it

German Foreign Minister Johann Wadephul and Interior Minister Alexander Dobrindt blamed Russia at a joint press conference on 1 September, ordering the closure of Russia's last consulate in the country and scrapping the agreement behind Moscow's cultural center in Berlin. Russia's embassy claims more than 150 of its mission staff and their families must now leave Germany, and Moscow answered by closing the German consulate in St Petersburg and the Goethe institutes.

Four days after the attribution, German investigators suspected Russian intelligence behind an arson attack on a defense company.
