Last week’s alert at a NATO base in Germany housing the Western alliance’s fleet of AWACS surveillance planes was due to a potential drone threat, a security source said on Monday.
Geilenkirchen air base in western Germany raised its security level to “Charlie” – the second highest of four – during most of Friday.
German news agency dpa, citing security sources, said there had been a tip-off from a foreign intelligence service about a possible Russian act of sabotage.
But the security source told Reuters no drones had been seen and could not confirm any evidence of a Russian role.
“The word Russia was never mentioned. We talked about a threat caused by drones,” added a NATO spokesperson at Geilenkirchen.
The German government press office, the interior ministry and Moscow’s embassy in Berlin did not immediately comment on the media report of a Russian threat.
Western forces are on high alert amid widespread reports from intelligence services and Western media of possible Russian acts of sabotage against nations supporting Ukraine in its war against Russia.
Russia, which invaded Ukraine in February 2022, has rejected the assertions and accuses the West of aggression towards it.
Last week, Geilenkirchen base also raised the security level after a nearby military base was temporarily sealed off as authorities investigated possible sabotage to the water supply.
