From the website:
Thousands of Belgians were thrown into a panic by news that the Flemish half of the country had declared independence. A two-hour live television report on the break-up of the nation showed images of ecstatic Flemish nationalists waving flags on the streets and queues of French speakers heading for the “border”.
The panic turned to anger after RTBF, the French public broadcaster, admitted 40 minutes into the show that it was a hoax designed to dramatise tensions between Flanders, in the north, and French-speaking Wallonia, in the south.
Thousands of viewers called the station during the broadcast, some of them in tears over the “death of Belgium” and reports that the King had fled.
