France fretting over fan safety

French authorities are agonizing over how to ward off potential terrorist attacks on hundreds of thousands of fans expected for the European Championships, which start 100 days from Wednesday.

Fan zones in the 10 host cities are feared to be potential targets, and millions of dollars are being spent on security precautions for the 24-nation competition that runs from June 10 to July 10.

Up to 80,000 fans have been predicted for the Prado beach venue in Marseille, 60,000 at Place des Quinconces in Bordeaux and 10,000 in a park next to Nice's landmark Promenade des Anglais.
