WARSAW, Poland — Polish officials say a Lufthansa plane that was approaching Warsaw’s international airport nearly collided with a drone.

The spokesman for Warsaw’s airport, Przemyslaw Przybylski, said Tuesday that the incident happened Monday afternoon around 4 p.m., and the drone was within 100 metres (300 feet) of the plane arriving from Munich.

He said the near-collision occurred about 5 kilometres (3 miles) from the airport.

He added that police are investigating the incident to determine who operated the drone, which should not have been where it was.

Mikolaj Karpinski, with the Polish Air Navigation Services Agency, told the TVN24 broadcaster that the pilots immediately reported the drone to air traffic controllers, who redirected the plane’s path. Karpinski said he considered the incident serious.
