German of the day: Anschlag. That means attack.

It’s the Islamist way to say Merry Christmas!
Security hiked at Cologne Cathedral for Christmas amid attack threat – German police said on Saturday they were heightening security at Cologne Cathedral following indications of an attack planned for New Year’s Eve and in the wake of government warnings in recent weeks about the rising threat of Islamist violence.
The police said in a statement they would use tracker dogs to check the cathedral after evening mass and then close it off. On Sunday, Christmas Eve, they would carry out a security check on all visitors, and recommended they get to services early.
