Denmark is urgently calling up soldiers after Russian drones were spotted crossing into the NATO nation's territory.The latest development comes as Europe is on edge over reports of suspected Russian aircraft being spotted above EU military bases.

Denmark will impose a blanket ban on civilian drone flights ahead of a visit by European leaders to Copenhagen next week.

Boosting NATO's presence close to Denmark sends "a message of assurance and cohesion within the Alliance," says a spokesperson.

More drones have been spotted in the airspaces of Denmark and Lithuania, stoking security concerns and fears amid suspected growing Russian aggression.

The incidents come as Russian drones and military aircraft have increasingly entered NATO airspace, prompting heightened alert and readiness across the alliance.

Denmark's defense chief has called a series of unidentified drones being spotted near airports and military installations a "hybrid attack."

Danish Prime Minister Mette Frederiksen called it “the most serious attack on Danish critical infrastructure to date.”

Denmark is probing potential Russian involvement after enduring the second drone attack this week as authorities are bracing for the possibility of more incidents. Large professional drones spotted at several airports and military air bases in Denmark disrupted flights and sparked a major police operation overnight.
