Officials in Germany say they believe it is terrorism – as police hunt for an attacker who killed a 56 year-old woman and two men aged 57 and 67 at a city festival. Eight others were injured when a man began stabbing people at random at around nine thirty last night. A 15 year-old has been detained as part of the investigation. The attack happened in the western city of Solingen – where 80 thousand people were gathering for the three day festival.
