Cologne-Bonn’s confidential emergency plan was posted on its site for several months, the German broadcaster ZDF said, heightening concerns about security after the Brussels Airport attacks.
ZDF said the document, over 320 pages long and meant for internal use only, included instructions on how to deal with natural catastrophes, air accidents as well as terrorist attacks, bomb threats and hostage takings.
The SITE Intellingemce group reported last month that ISIS had posted pictures on the internet calling German Muslims to carry out Brussels-like attacks at Cologne-Bonn and at the office of Germany’s chancellor offices.
The document included detailed descriptions of where the passengers should gather in emergencies and had been on the airport’s website since 2015. It was removed after a query by ZDF.
