Bus starts smoking in Mont Blanc tunnel; 68 people evacuated

Dozens of passengers have been evacuated from a double-decker bus in the Mont Blanc tunnel after the vehicle started spewing smoke

ROME -- Dozens of passengers have been evacuated from a double-decker bus in the Mont Blanc tunnel after the vehicle started spewing smoke.

Firefighters said an unspecified mechanical problem in the bus triggered the smoke.

Attention to safety in the 11.6-kilometer (7.2-mile) Alpine tunnel between France and Italy was heightened after a 1999 fire that killed 39 people.

Within two hours Wednesday, traffic was reported flowing again in both directions in the tunnel, a major trans-Alpine route.
