Update: Here's a report from the AP:
APELDOORN, Netherlands (AP) - A speeding car raced toward an open bus carrying Dutch Queen Beatrix and her family during a holiday parade Thursday and plowed into spectators, killing four people and injuring 13 others, authorities said.Saying that he's white is not enough to give a description.
Prosecutors said they believe the incident was deliberate, but not an act of terrorism. They did not indicate a motive or say why the popular queen might have been a target. The driver was a 38-year-old white Dutch male with no police record or history of mental illness, police said. They would not give his name.
