A speeding car raced toward an open bus carrying Dutch Queen Beatrix and her family during a holiday parade Thursday and careened through spectators.
Dutch television said two people were killed and about a dozen injured, but police in Apeldoorn declined to confirm the casualty toll or to say whether the incident was a deliberate attack on the royal family.
The small black car appeared to be heading at high speed toward the royal bus and passed within a few meters of it before plowing into a stone monument. The incident was witnessed by The Associated Press.
People were seen flying through the air after the car swerved across police railings, where the crowd was lined up five or six deep to see the immensely popular royal family pass on its way to the Het Loo palace on the Queen's Day national holiday.
It was not clear how the car managed enter the parade area, which police had sealed off hours before.
