Drones flew over Aalborg Airport in northern Denmark overnight on Wednesday into Thursday, as well as over three smaller airports in the country, but it was not immediately clear who was behind the incidents, authorities said.

Defence Minister Troels Lund Poulsen called it a “hybrid attack” because the flights all occurred within roughly the same timeframe.
