All domestic and international trains at Gare du Nord, Europe's busiest train station, came to a halt Friday after an unexploded World War II shell was discovered, officials said.

The discovery of the unexploded WWII bomb outside of Paris caused all Eurostar traffic coming in and out of Gare du Nord station to be “completely halted,” the railway company told PEOPLE in a statement.
