Brother urges Berlin truck attack suspect to give himself up

Authorities across Europe are hunting a Tunisian man suspected of killing 12 people by driving a truck into a Christmas market in Berlin, as one of his brothers urged him to surrender.

German authorities have issued a wanted notice for Anis Amri and offered a reward of up to €100,000 for information leading to the 24-year-old's arrest - warning that he could be "violent and armed".
