Three family members from Hong Kong were seriously injured and one slightly injured in the attack in the southern German city of Wurzburg. Another 14 were treated for shock.

Bavarian Interior Minister Joachim Herrmann said the attacker, a teenage Afghan refugee armed with an axe and knife, was killed as he tried to flee the scene.

Daesh claimed responsibility for it, and a home-made Daesh flag was found in the assailant's room makes.

The minister has called for an investigation into the degree of the boy's involvement with the group, and how he was radicalised so quickly.

Police reports indicate that the attacker, is said to have have travelled to Germany as an unaccompanied minor, had fled the train but was chased by officers who shot him dead.

The BBC, citing the South China Morning Post, believe the four injured to be a 62-year-old man, his 58-year-old wife, their daughter, 27, and her boyfriend, 31. The 17-year-old son travelling with them was not hurt, the Chinese newspaper said.
