HONG KONG (AP) — Hong Kong officials said Tuesday that four members of a family from the semiautonomous southern Chinese city were hurt in an ax and knife attack on a German train.

The city's immigration department said that it was providing assistance to the family following the attack in the southern city of Wuerzburg.

Wuerzburg police shot and killed the teenage Afghan migrant who carried out the attack. The force said on its Facebook page that three victims suffered serious injuries, a fourth was slightly injured and 14 more were being treated for shock.

The South China Morning Post newspaper reported that the family members hurt included the 62-year-old father, 58-year-old mother, 27-year-old daughter and her 31-year-old boyfriend.

A fifth family member, a 17-year-old son, was not hurt. The paper did not cite its source.

Hong Kong's top official, Chief Executive Leung Chun-Ying, condemned the attack and extended his sympathies to the victims and their families.

A statement from his office said that representatives from Hong Kong's office in Berlin were visiting the injured Hong Kong residents.
