A German court sentenced a 16-year-old girl to six years jail on Thursday for an attack on a police officer in what prosecutors described as the first assault ordered by ISIS in the country. The teenager, identified as Safia S, was 15 years old when she slashed the police officer in the neck with a vegetable knife at the main railway station in Hanover in February last year. The 34-year-old policeman was severely injured but survived the attack.
