Explosive drone found at Leipzig airport near Ukrainian ammunition plane

On a Tuesday night just before midnight, an airport worker at Leipzig spotted something that should not have been there: a drone, hovering low between two massive cargo planes. The aircraft belonged to Antonov Airlines, the Ukrainian carrier that has used this German airport as a European hub since Russia's invasion began in 2022. One of those planes was loaded with military ammunition. The other carried a tank filled with jet fuel—cargo that had arrived from France only hours before, destined for Ukraine. What the worker had found was a device roughly the size of a fist, packed with semtex explosive and rigged with a remote detonator. The detonator was broken. Had it worked, German officials would later say, the consequences could have been catastrophic.

Leipzig airport sits just twelve kilometers from the center of a city of more than 600,000 people. It is not a minor facility. The airport runs a major cargo processing center that operates around the clock, employing hundreds of workers. It sits adjacent to two busy autobahn routes. It is classified as critical infrastructure by the German government and serves as a logistics hub for NATO and the German military. The discovery of an explosive device on its tarmac, positioned between planes carrying ammunition and fuel, represented a threat at a scale that officials struggled to articulate without sounding alarmist.

Interior Minister Alexander Dobrindt told reporters on Wednesday that Germany faced a "new level of danger." He emphasized that only the apparent malfunction of the detonator—what he described as a "ripped" mechanism—had prevented the drone from detonating. The device itself appeared to have been modified to evade the airport's electronic detection systems, which had failed to register its presence. Security footage later showed the drone had been on the ground for several hours before anyone noticed it.

The incident did not end with the discovery of that first device. When authorities suspended air traffic to investigate, a DHL cargo plane approaching from Marseille was forced to abort its landing and climb back into the sky. As it did, it collided with what investigators believe was a second drone. That second drone carried a camera—equipment used to film an attack. The DHL plane, which had been carrying unspecified dangerous goods, made an emergency landing in Hanover, roughly 250 kilometers away, sustaining minor damage. The pattern suggested coordination, not accident.

German authorities stopped short of naming Russia directly, but the suspicion was unmistakable. Roderich Kiesewetter, a member of parliament's intelligence committee, did not hesitate. He called the incident a "targeted hybrid attack" and "an attempted act of terrorism orchestrated by Russia." The assessment aligned with a documented pattern. In July 2024, a firebomb had been mailed through DHL and exploded at this same Leipzig facility. A second incendiary device was sent to the United Kingdom, where it caught fire at a warehouse in Birmingham. Similar packages were found in Poland. A pan-European investigation identified 22 suspects in Lithuania and Poland suspected of working for Russian intelligence. At a trial in Lithuania this week, testimony revealed how narrowly that earlier attack had succeeded—the parcel at Leipzig had ignited on the ground only because the plane was delayed, not in the air where it would have been catastrophic.

Leipzig airport had resumed normal operations by Thursday, with air traffic diverted temporarily but no additional security measures announced. Ukraine has relied on this facility for military transport since the full-scale invasion began, using it as an alternate route when other channels were compromised. German defense officials said their own armed forces were not conducting military operations there at the time of the incident. The question now facing investigators is whether this attack, like the firebombs before it, was part of a sustained campaign to disrupt the flow of weapons to Ukraine—and whether the next device will have a functioning detonator.
