Two drones entered NATO member Latvia from Russian territory and were shot down, the Latvian military announced on Thursday morning.
The drones were probably launched from Ukraine against targets in Russia, Latvia's Defense Minister, Andris Spruds, told national broadcaster LSM.
Military aircraft from NATO's multinational Baltic air policing mission have been called to the scene, he added.
According to police, four empty oil tanks were damaged at a storage facility in Rezekne, about 40 km from the Russian border, and possible remains of a downed drone were found at the scene, Reuters reports.
Latvian authorities had issued drone alerts to residents along the Russian border at 4:09 a.m. local time, urging them to stay indoors.
All schools will be closed in Rezekne on Thursday, the municipality has announced.
