Referring to the deadly truck attack in Berlin by a Tunisian asylum seeker, she said it was "sickening" when acts of terror were carried out by people who had sought protection.

But she also said she was confident Germany could overcome them.
"As we go about our lives and our work, we are saying to the terrorists: 'You are hate-filled murderers, but you do not determine how we live and want to live. We are free, considerate and open'," Mrs Merkel said.
