Denmark says new drone sightings overnight at military installations

COPENHAGEN (Reuters) -Unidentified drones were observed near military installations in Denmark overnight, the Armed Forces said on Saturday, according to broadcaster DR, following several drone incursions near airports and critical infrastructure this week.

The Armed Forces did not specify where the drones were observed.

Police said they had observed drones near the Karup air base in western Denmark, Ritzau News agency reported.

Copenhagen Airport, the Nordic region's busiest, closed for several hours late on Monday as several large drones were seen in its airspace. Five smaller airports, both civilian and military, were also shut temporarily in the following days.

Danish authorities have called the incursions hybrid attacks, and Prime Minister Mette Frederiksen said earlier this week it was "the most serious attack on Danish critical infrastructure to date."
