The letters have ongoing operations all the time, where they try to observe drones and are also ready to combat them, says Albinus, who is the chief of Nato's northern division, to DR.
She does not want to specify when drones were last seen there and not how often it has happened, but confirms that drones have been observed over the base.
The Nato base is located in Adazi, about 20 kilometers outside Riga and about 200 kilometers from the Russian border.
