There have been several instances of unidentified drones flying over military bases recently.

At least 10 such drones had been seen flying above Manching Air Base near the city of Ingolstadt on Sunday evening, German police said.

Last month, there were sightings at Manching and nearby Neuburg an der Donau.

Drones were also spotted at the US air base at Ramstein and at an industrial zone near it in the North Sea.

In her statement, Interior Minister Faeser said “espionage or sabotage are regularly considered as a possible reason”.

Under the current rules, the German Army can only help police to force drones to move away or to land – but also to fire warning shots to make this happen.

Under the new proposals – which still need parliamentary approval – soldiers may shoot a drone down if they think that is the only way to deal with the danger it poses “against the lives of people or against a critical facility”.
