In another poster there are images of landmarks such as the Eiffel Tower in Paris during Christmas time with dark terrorist images, including a hand holding a bloody knife.
The images also include phrase “soon on your holidays” in English, German and French.
The latest threats come after six Syrians were detained on Tuesday for allegedly planning an attack using weapons or explosives in Germany.
The suspects, aged between 20 and 28, were arrested by German police during raids in the cities of Kassel, Hanover, Essen and Leipzig, the general prosecutor's office in Frankfurt said in a statement.
The attack was planned on a Christmas market and those held were arrested at a refugee camp, according to reports.

Earlier this year on August 17 a terrorist ploughed a van into crowds, killing 13 people and injuring more than a hundred, in Barcelona's Las Ramblas in the afternoon.
Just after midnight on June 19 a van driver mowed down Muslim worshippers on Seven Sisters Road near Finsbury Park mosque in London. One person was killed and several were injured.
Another terror attack that happened in London killed eight people and injured many others on London Bridge and in nearby Borough Market on June 3. Three men armed with knives drove over pedestrians on the bridge and went on killing spree at nearby pubs.
One of the worst terror attacks this year was the Manchester bombing during Ariana Grande’s concert. A lone suicide bomber detonated explosives killing 22 people, including children and injuring another 59.
