No one knows where that car came from, and how it could have gotten through security. The roads had been blocked off for the royal cortege, after all. The media are still referring to it as 'an accident', but it could of course have been something much more sinister than that.
All we know is at the moment, there are 14 people seriously injured, and an unconfirmed report says that there's one fatality. All further festivities in Apeldoorn have been cancelled, and the royal family has been advised not to venture out in public again today.
