During my stay in Germany there was a major terror alert on Wednesday which reportedly threatened Frankfurt Airport and Ramstein.
When I was due to fly out to Hong Kong on Friday, my check-in area at Frankfurt Airport was evacuated due to an unattended suitcase being left in the hall. The police only kept us a safe distance away instead of evacuating the whole building. This was during the late afternoon rush hour and passengers had a ring site view of the bomb squad first x-raying the suitcase, then simply had a dog sniff it and the rather brave bomb squad officer opening the suitcase and emptying its, what looked like Indian subcontinental clothing, in a heap on the floor. It was all over in less than an hour and check in was not that much delayed.
Here's a picture I took when the evacuation was in full progress:
