A passenger jet heading toward England was diverted to Germany on Saturday after three men on board were heard talking about terrorism, NBC News reported.
Authorities conducted the controlled detonation of a backpack as a precaution, police said.
Three men were detained after the easyJet flight from Slovenia’s capital Ljubljana to London Stansted Airport made an unscheduled stop in Cologne, a spokesman for the German Nordrhein-Westfalen police said.
Passengers told staff they heard men were talking about terrorism, which lead to the stop in Germany. The exact wording of what was said was not immediately available.
Authorities are awaiting more analysis about what was inside the backpack they exploded. It has not been determined that it contained explosives, police said.
