A girl aged 16 has been jailed by a German court for six years for what is seen as the country's first attack by a sympathiser of jihadist group Islamic State (IS).

Safia S, who was 15 at the time, stabbed and seriously wounded a police officer at the central station in Hanover.

Prosecutors described the attack as ordered and supervised by IS.

She was convicted of attempted murder and helping a terrorist organisation.

Safia S, described as a German Moroccan, was also found guilty of grievous bodily harm. Her defence had called for her to be cleared of the other charges and given a lesser sentence.
