Germany's Leipzig/Halle Airport has fully resumed flight operations after an explosive-laden drone was discovered near a Ukrainian cargo plane, an incident authorities are investigating as a serious security matter potentially involving foreign powers and a hybrid attack scenario.

An airport official confirmed Thursday morning that operations are back to normal, following the diversion of several planes, including a passenger jet, and the closure of parts of the airport. The drone, fitted with an explosive device and detonator, was found overnight into Wednesday near the airport's south runway, close to cargo operations. The Federal Police’s bomb disposal unit successfully removed the detonator.

German Interior Minister Dobrindt described the event as a "very serious, security-related incident" and a "hybrid attack scenario." While not ruling out sabotage, he cautioned against speculation regarding the explosives' origin or construction, emphasizing the priority is a thorough investigation in all directions.

Authorities stated the case is being handled by the Central Office for Extremism Saxony and the state's terrorism unit. Further details were not immediately released due to the ongoing investigation, though officials assured there was no danger to passengers or staff.

In a separate, related incident, a second drone collided with a DHL cargo plane after it aborted its landing due to the runway closure. This aircraft later landed safely in Hanover, Germany, with minor damage.

Leipzig/Halle Airport is a significant hub for cargo and military equipment transport.
