The Berlin Christmas market where 12
people were killed on Monday by a suspected Islamist extremist who
drove a truck into a crowd has reopened.
Police have installed concrete barriers to prevent a repeat attack.Locations in Dortmund, Emmerich and Berlin were raided overnight in the hunt for Tunisian suspect Anis Amri.
Amri is the subject of a Europe-wide arrest warrant. His ID and fingerprints have been found in the lorry, officials say.
His brother, Abdelkader Amri, speaking near the family home in Tunisia, urged his brother to give himself up, saying: "If he did what he is suspected of having done, he will be sanctioned and it will be a dishonour for us."
But he said he was sure his brother was innocent, saying he had left for Europe "for economic reasons... to work, to help the family. He didn't go for [terrorist] reasons".
The lights were dimmed and the mood was sombre as the Breitscheidplatz market reopened.
Candles and flowers were laid for those who died - they included at least six Germans, an Israeli tourist and an Italian woman - and for the 49 people who were injured.
