# A sighting of a suspected drone briefly shuttered a Danish airport today for the second time in a few hours, after the country’s prime minister said the flights were part of “hybrid attacks” that may be linked to Russia. Drones have been seen flying over several Danish airports since Wednesday, causing one of them to close for hours, after a sighting earlier this week prompted Copenhagen airport to shut down. That followed a similar incident in Norway, drone incursions in Polish and Romanian territory and the violation of Estonian airspace by Russian fighter jets.
