Meanwhile, passengers on the Eurostar speedboat at Gare du Nord station were evacuated in another terrorist warning in Paris on the evening of September 1 after discovering a suspicious object. "They found something suspicious. We all had to wait outside the station," said the Zoë Grisedale passenger.
