seine

An Olympics anti-terrorism perimeter along the banks of the River Seine seals off a miles-long area to Parisians and tourists who hadn’t applied in advance for a pass.

Triathlon and marathon swimming are to take place in the Seine, where it has been illegal to swim for more than a century. The water has tested unsafe in recent weeks, and cleaner on other days.

The river is expected to peak at around 19 1/2 feet later this weekend, but not before it swallowed up streets, halted all boat traffic and sent rats scurrying through the city.
