Germany's Interior Minister Alexander Dobrindt on Sunday warned that hybrid warfare attacks had become a daily threat to the country.

"We're not at war, but we are the daily target of hybrid warfare," Dobrindt told the newspaper Bild am Sonntag following the discovery of a drone carrying explosives at Leipzig/Halle Airport.

"Espionage, sabotage, cyberattacks, or covert operations by foreign powers aimed at destabilizing Germany or inflicting direct harm are a constant reality," Dobrindt said.

He also noted that the country is stepping up research into drones to address new security threats.

A new drone security research center will be established later in August at a German Aerospace Center (DLR) test airport in the eastern state of Saxony-Anhalt, Dobrindt said.
