Eurostar trains to London and all trains heading to northern France were brought to a halt Friday following the discovery of an unexploded World War II era bomb on tracks leading to the nation’s busiest station.

The police successfully defused the explosive device, which weighs more than 1,000 pounds and was found near tracks north of the French capital during landscaping work.

Speaking to the BBC before the French transport minister confirmed the WW2 bomb had been defused, Lejeune says they thought it was the "better option" to cancel all 32 services between London and Paris today because it would give passengers "clarity" amid the "uncertainty".
