The raiders are said to have escaped into France
Masked men have stormed a packed casino near the Swiss border city of Basel, making off with hundreds of thousands of francs (dollars), prosecutors say.
About 10 raiders pulled up at the Grand Casino in two cars just after 0400 (0200 GMT) and smashed their way in, brandishing machine-guns and pistols.
The French-speaking gang ordered the 600 guests and employees to the floor while they emptied registers.
The Grand Casino describes itself as the "Swiss Las Vegas" on its website.
Reports say they could not get into the strong room despite firing on the door.
Nobody was seriously injured in the robbery....
