“Of course, we all want to know which foreign powers are involved. But it would be reckless to give credence to any kind of speculation at this point,” he added.

Leipzig Airport serves as a strategic hub for NATO, including for military transports to Ukraine. The airport is also international courier service DHL’s largest European air hub and serves as a temporary home for some Ukrainian Antonov aircraft, protecting them from Russian attacks. The armed drone was found just meters away from such a plane, said officials Wednesday.

Armin Schuster, minister of the interior for Saxony — where Leipzig is located — told ZDF that the incident represented a new threat level.

“Without wanting to preempt the investigation, I would describe this as a suspected attack scenario because this is the first time we’ve had a drone that was also loaded with explosives,” he said. “That’s new.”

An airport worker found the drone Tuesday night. Officers disarmed the device by removing its detonator, which had failed to go off. In a separate incident at the same airport, another flying object struck a DHL cargo aircraft as it was being diverted away from the airport after the explosive-laden drone was found.
