Unidentified drones were spotted near military facilities in Denmark overnight, the armed forces said on Saturday, following several drone incursions near airports and critical infrastructure this week.
"The Danish Defense can confirm that drones were spotted at several Danish Defense Force locations last night. Multiple capacities were engaged," a spokesman said in response to Reuters.
The armed forces did not specify exactly where the drones were spotted.
Police said the drones were seen near the Karup military base in western Denmark, the Ritzau news agency reported.
Norwegian police said on Saturday they were investigating drone sightings near Oerland Air Base in central Norway, which is the main base for Norway's F-35 fighter jets.
"Guards at the base observed more activity outside the base perimeter in the early morning hours," a spokesman for the Norwegian Armed Forces Joint Staff told Reuters.
Copenhagen Airport, the busiest in the Nordic region, was closed for several hours late on Monday after several large drones were spotted in its airspace. Five smaller airports, both civilian and military, were also temporarily closed in the following days.
Danish authorities have characterized the intrusions as hybrid attacks, with Prime Minister Mette Frederiksen saying earlier this week that it was "the most serious attack on Danish critical infrastructure to date."
