De Maizière also confirms that the man who has been arrested on suspicion of carrying out the attack has denied the charges.

The arrested man is from Pakistan, and arrived in Germany on 31 December 2015. He arrived in Berlin in February. The suspect spoke a dialect for which no translator could be found, the minister said.

De Maizière says he is not giving much attention to the Isis message claiming responsibility for the attack.

He confirms he will attend the vigil for the victims at 6pm in the memorial church on the square where the attack took place.

De Maizière said police will not rest until they have completed their investigation into the attack.

He urged once again for Christmas markets to remain open, but warned people to remain vigilant. He said it would be “a lovely idea to go to a Christmas market and buy a crib”.
