The bomb was discovered in Paris around 4 a.m. by workers doing earth-moving work near the tracks in the Seine-Saint-Denis region. Eurostar trains to and from London were brought to a halt.

A half-ton World War II-era bomb found by workers near train tracks outside of Paris is disrupting train and road travel across the region.

Decades after the end of heavy bombing during the First and Second World Wars, France is still dealing with millions of unexploded bombs, mines and other artillery buried in the ground.
