Don´t know, if this is interesting, but Düsseldorf Airport (Dusseldorf / EDDL / DUS) is currently closed due to an unattended suitcase found in the departure area in Terminal A or B.

All incoming flights are diverted to other airports, all outgoing planes are not leaving right now.
Planes that were in process to disembark are parked on remote locations (People are still sitting in their planes since 6 pm local time)

German news (spiegel.de) are reporting, that the police is investigating right now but they are unsure, if they will reopen the airport soon ...
