Travel chaos spread throughout the region on Friday when a half-ton World War II-era bomb was discovered near train tracks in a densely populated residential area just outside Paris. This led to disruptions at Europe’s busiest rail station and the closure of major roads leading into the French capital.Â
The unexploded bomb was found during earthmoving activities near the tracks in the Seine-Saint-Denis area north of Paris by workers. French Transport Minister Philippe Tabarot confirmed the discovery.Â
Bomb disposal experts were called to the site, locals were evacuated, and a significant security perimeter was established around the operation to ensure safety, according to Tabarot.Â
