5 injured, including 2 Americans, in stabbing attack in Amsterdam, police say

A knife-wielding assailant in Amsterdam seriously wounded five people — including two from the United States, one from Belgium and one from Poland — in a stabbing attack Thursday on a busy shopping street, Dutch police said.

The attack occurred at around 3:30 p.m. local time and lasted several minutes before the assailant was stopped by a passerby near the city’s Dam Square. Police cordoned off the area and several ambulances and a trauma helicopter were called to the scene.

Authorities said in a statement that no motive had been established for the attack, but that police were considering a scenario where the man targeted victims at random.

“The suspect was detained with the help of a civilian,” police spokesperson Eline Roovers told The Associated Press. The identity of the suspect was still being investigated, police said.
