According to the dutch news site De Telegraaf
and De Volkskrant
, the stampede occurred after a man dressed in traditional Orthodox Jewish garb cried "Bomb! Bomb! Run!" The man yelled the warning during a two minutes of silence during a vigil.
With today's population being ever fearful of terror acts, the warning was enough to send the crowd running. Security officials also escorted Queen Beatrix, her son Crown Prince Willem-Alexander and his wife Princess Maxima to safety.
A video posted on YouTube (the video is in dutch) shows some of the action, however the commenter seems unaware of what was going on.
According to Reuters
, police are holding the man responsible for causing the panic in custody. As Reuters reports, "The 39-year-old man, would also be charged for injuries incurred as well as for disturbing public order at Tuesday's ceremony, warranting his continued detention, the prosecutor's office said."
The Netherlands hold an annual World War II Remembrance Day ceremony every May 5. In recent years, Remembrance Day also honors soldiers and others who died in more recent conflicts.
