Drones disrupt Copenhagen Airport in Denmark’s worst infrastructure attack

Large drones that flew over Copenhagen Airport for hours and caused it to shut down were the “most serious attack on Danish critical infrastructure” to date, Prime Minister Mette Frederiksen said on Tuesday.

Airports in Copenhagen and Oslo reopened early on Tuesday, hours after unidentified drones in their airspace caused dozens of flights to be diverted or cancelled, disrupting thousands of passengers.

“This is part of the development we have recently observed with other drone attacks, airspace violations, and cyberattacks targeting European airports,” Frederiksen said in a statement.

She referred to similar drone incidents in Poland and Romania and the violation by Russian fighter jets of Estonia’s airspace.

The governments of Poland, Estonia and Romania have pointed the finger at Moscow, which has brushed off the allegations.

The Kremlin on Tuesday denied any involvement in the drone flights over Copenhagen Airport.

“We hear unfounded accusations from there every time. Perhaps a party that takes a serious, responsible position shouldn’t make such unfounded accusations time and again,” Kremlin spokesman Dmitry Peskov told reporters.
