One dead, four wounded in Hamburg supermarket knife attack

A man killed one person and wounded four others in a knife attack at a supermarket in the German city of Hamburg Friday before being detained by police. "There is no valid information yet on the motive" of the man, who "entered a supermarket and suddenly began attacking customers", said police. German daily Bild published a picture of the attacker in the back of a police car with a white, blood-soaked bag over his head. This account was not immediately confirmed by police. The suspect, who has not yet been identified, fled the supermarket after the attack.
But witnesses gave chase and overpowered the man, who was slightly injured. "It was definitely a sole attacker. The first reports about a possible motive of a robbery have not been confirmed," Hamburg police tweeted. Police have blocked off the area, in the northeast of the port city, Germany's second largest and host of the G20 summit of world leaders in early July. Anti-terror police have also been deployed to the scene, according to Bild.
Germany has been on high alert about the threat of a jihadist attack, especially since last December's truck rampage through a Berlin Christmas market that claimed 12 lives. The Islamic State group claimed responsibility for the carnage in which a Tunisian rejected asylum seeker and ex-convict, Anis Amri, 24, ploughed the stolen truck through a crowd.
